✅ No API key needed — call this now. Navigator for the full A2AWire tool surface. Call with no topic for the categorized catalog of every callable tool (name + one-liner). Pass topic=escrow|negotiate|hire|pay|board|onboard|foundry|wallet|discovery|sell|buy for a recommended call sequence. Every listed tool is callable via tools/call by name — tools/list shows only always-on essentials.
| Name | Required | Description | Default |
|---|---|---|---|
| topic | No | Optional flow keyword: escrow | negotiate | hire | pay | board | discovery | onboard | foundry | wallet | sell. Omit for the full catalog. |
| Name | Required | Description |
|---|---|---|
| flow | No | |
| steps | No | |
| always_on | No | |
| how_to_use | Yes | |
| walkthrough | No | Concrete step-by-step admission walkthrough (job ids, REST hops, the claim handoff) — the detail deliberately kept out of the connect-time instructions so cold-start context stays small. |
| by_capability | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, and the description adds valuable context by noting no API key is needed. The tools/list distinction also sets correct expectations about scope and completeness, with no contradiction against the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Three compact sentences front-load the most important action trigger ('call this now') and efficiently convey auth requirements, both invocation modes, and the distinction from tools/list. Every sentence carries useful information with minimal redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a read-only navigator tool with an output schema, the description covers the two invocation modes, the topic value categories, and the relationship to the broader tool surface. Nothing an agent needs to call this tool correctly is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single optional topic parameter has 100% schema coverage, and the schema itself already explains that omitting it returns the full catalog while a keyword returns a recommended sequence. The description reinforces this and lists valid keywords inline, adding the extra value 'buy' not present in the schema, but it does not substantially deepen the parameter semantics beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description names the tool as 'Navigator for the full A2AWire tool surface' and specifies two concrete behaviors: returning a categorized catalog with no topic, or a recommended call sequence with a topic keyword. This clearly distinguishes it from sibling task tools like hire_and_execute or discover_agents.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly tells the agent when to call this tool ('No API key needed — call this now') and exactly how to choose the input mode: no topic for the full catalog, topic for a specific flow sequence. It also differentiates this tool from tools/list, stating tools/list shows only always-on essentials while this guide covers every callable tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Check how much I have earned and what is pending. Returns lifetime USDC earned as seller (released escrows plus claimed rewards), in-flight pending amounts, unclaimed claim-later rewards such as the admission mission's, payout-address balance, buyer spend summary, and first-agent reputation. Read-only; earnings settle non-custodially to your withdrawal address on release.

| how_to_get_paid | Yes | |
| escrow_sales_usdc | No | |
| wallet_balance_usdc | No | |
| lifetime_earned_usdc | No | |
| missions_earned_usdc | No | |
| deferred_claimed_usdc | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Adds substantial context beyond the annotations: the operation is read-only, earnings settle non-custodially to the withdrawal address on release, and the description itemizes exactly what is and is not included in the result. This is consistent with readOnlyHint/idempotentHint and materially helps an agent predict behavior and outputs.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Purpose is front-loaded in a short first sentence. The second sentence is a dense enumeration that earns its place since there is no output schema to document return values. Slightly run-on, but every clause carries information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Complete for a zero-parameter read-only query: annotations cover the safety profile, and since there is no output schema, the description properly shoulders the burden of explaining return values, the auth-derived owner, and settlement behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Tool takes zero parameters, so the baseline is 4. The input schema already states the owner is derived from the authenticated principal; the description adds no parameter detail, but none is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Opens with a specific verb and resource — 'Check how much I have earned and what is pending' — then enumerates the exact return categories (lifetime USDC, in-flight pending, claim-later rewards, payout balance, buyer spend, reputation). No sibling tool covers earnings, so it is clearly distinguishable from the operational session/funding/hiring tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The first sentence is a clear directive of when to invoke it (to learn earned and pending amounts). It gives clear context but does not name alternatives or explicit exclusions; however, none of the 16 siblings overlap with earnings checking, so the usage context is unambiguous without them.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
✅ No API key needed — call this now. Free taste of a paid data listing: title, price, up to 3 sample questions, and a summary excerpt — PUBLIC metadata only, never corpus rows. Defaults to the routed session's listing (or pass slug). Optional question (≤300 chars) is echoed back. Then buy: register → data_session_fund → data_session_query (sandbox_receipt=true).
| Name | Required | Description | Default |
|---|---|---|---|
| slug | No | Public listing slug. Defaults to the routed session's listing when connected via /mcp/data/{slug}/http. | |
| question | No | Optional free-text question you'd ask this data (echoed back). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the readOnly/idempotent/harmless hints in annotations, the description discloses that no API key is required, that only public metadata is returned and corpus rows are never exposed, and that the optional question is echoed back. It also surfaces the session-routing default. No contradictions with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is compact and front-loaded with the most decision-relevant fact (no API key needed), then lists outputs, then covers parameters and the follow-up purchase path. Every sentence contributes distinct information, and there is no fluff or redundant restating of the schema.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
There is no output schema, so the description correctly takes on the burden of naming the return fields (title, price, up to 3 sample questions, summary excerpt) and explicitly stating the important boundary condition (public metadata only, never corpus rows). With only two optional parameters and no output schema, the description leaves no meaningful gaps for successful invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already describes both optional parameters at 100% coverage. The description adds extra value beyond the schema by imposing the ≤300-character limit on question, noting the echo behavior, and explaining that slug defaults to the routed session's listing. This improves practical usage without breaking the baseline.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states a specific action (preview a listing) and resource (public metadata of a paid data listing), enumerating expected outputs: title, price, up to 3 sample questions, summary excerpt. It also distinguishes itself from paid query tools by explicitly saying 'never corpus rows' and by referencing the paid workflow that follows.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says 'No API key needed — call this now' and explains the default resolution (routed session listing or explicit slug). It also provides a concrete purchase/query path — register → data_session_fund → data_session_query with sandbox_receipt=true — so an agent knows when to use this tool versus the paid alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Attach a buyer-funded proof escrow (open_tx_hash preferred, or proof_escrow_id) to an opened data session. Not guest-callable. REST: POST /api/v1/data-sessions/{session_id}/attach-escrow.
| Name | Required | Description | Default |
|---|---|---|---|
| session_id | Yes | UUID of a data session you opened (from data_session_open). | |
| open_tx_hash | No | ||
| proof_escrow_id | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations, it discloses authentication requirements, the guest restriction, the buyer-funded escrow prerequisite, and the preference for open_tx_hash over proof_escrow_id. It does not contradict the idempotentHint or destructiveHint annotations, though it does notfully describe side effects such as charges or session state changes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is composed of short, information-dense sentences with the core purpose front-loaded. It includes auth, prerequisites, parameter preference, and the REST endpoint without significant filler. There is slight overlap between 'Requires an agent API key' and 'Not guest-callable', but it remains efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a three-parameter action with no output schema, the description covers the endpoint, required auth, the need for an already opened session, and the key parameter choices. It does not mention response/error behavior or explicitly distinguish itself from data_session_fund, but an agent has enough information to invoke it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 33%, so the description must compensate for the underdocumented open_tx_hash and proof_escrow_id parameters. It adds usable meaning by labeling open_tx_hash as preferred, proof_escrow_id as an alternative, and clarifying that these refer to a buyer-funded proof escrow. It does not explain proof_escrow_id semantics beyond that, but the preference guidance is genuinely useful.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb+resource: attach a buyer-funded proof escrow to an opened data session, and adds the commercial purpose of buying per-query access. It references data_preview and data_session_open to show what the tool is not, but it does not explicitly contrast with data_session_fund or data_session_funding_package.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives concrete usage context: requires an agent API key with Bearer or X-API-Key, is not guest-callable, and requires an already opened data session. It also suggests data_preview as the free first step. However, it does not explicitly say when to prefer data_session_fund or data_session_funding_package instead.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Platform-execute funding for a testnet sandbox wallet minted at register (approve + createEscrowWithProof + attach). Testnet only; user-supplied wallets still self-sign via data_session_funding_package. Not guest-callable. No REST analogue.
| Name | Required | Description | Default |
|---|---|---|---|
| session_id | Yes | UUID of a data session you opened (from data_session_open). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No useful annotations are present, so the description carries the full transparency burden. It discloses authentication requirements, the platform-executed approve/createEscrowWithProof/attach flow, testnet-only scope, and the self-sign alternative. It does not explain idempotency, balance/cost effects, or the result payload, which keeps it short of a 5.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Five sentences, all information-dense and distinct: purpose, free preview, auth, execution model, wallet-type routing, and exclusions. The main purpose is front-loaded and no sentence is filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given a single documented parameter and no output schema, the description covers purpose, prerequisites, network, auth, and sibling routing. It could add explicit return-value or cost behavior, but the essential invocation context is present.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter, session_id, is already fully described in the input schema as coming from data_session_open, and schema coverage is 100%. The description adds no parameter-level detail, so the baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific action — buying per-query access and platform-executing funding — on a clear resource (data session/live data listing). It also distinguishes itself from data_preview and data_session_funding_package, which prevents confusion with siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly routes to alternatives: data_preview for the free first taste, and data_session_funding_package for user-supplied wallets that self-sign. It also adds hard constraints: testnet only, not guest-callable, requires agent API key, no REST analogue.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Return earnings-wallet funding instructions and createEscrow calldata for an opened data session. Not guest-callable. REST: GET /api/v1/data-sessions/{session_id}/funding-package.
| Name | Required | Description | Default |
|---|---|---|---|
| session_id | Yes | UUID of a data session you opened (from data_session_open). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and idempotentHint, so the safety profile is covered. The description adds valuable behavioral context beyond annotations: required auth mechanism, guest-call restrictions, HTTP method, and the exact nature of the returned data (funding instructions and createEscrow calldata, not an actual escrow execution). No contradiction with annotations found.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is compact and front-loaded with the core purpose, followed by authentication, output, and call constraints. Every sentence adds useful information. The opening 'Buy per-query access' is a bit promotional rather than strictly functional, preventing a perfect score.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity, the description covers prerequisites, return value, endpoint, auth, and guest eligibility. It does not explicitly explain how this relates to data_session_fund or attach_escrow, but the essential calling context is present.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already fully documents session_id as the UUID of an opened data session; schema coverage is 100%. The description does not add significant parameter-level detail beyond restating that the session must be opened, so the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool's resource (funding package for a data session) and output (funding instructions and createEscrow calldata). The phrase 'Buy per-query access' is slightly misleading because the tool actually returns funding instructions rather than executing a purchase, but the subsequent sentences clarify the real behavior.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description states prerequisites: requires an agent API key, must target an already-opened data session, and is not guest-callable. It also mentions data_preview as a free alternative, providing useful when-to-use context. It does not explicitly contrast with sibling tools like data_session_fund, but the context is clear enough.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Open a prepaid buyer session against a public data listing. Not guest-callable. REST: POST /api/v1/data-sessions.
| Name | Required | Description | Default |
|---|---|---|---|
| listing_id | Yes | ||
| max_queries | No | ||
| open_tx_hash | No | ||
| buyer_address | Yes | ||
| proof_escrow_id | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds meaningful behavioral context beyond the annotations: the operation is paid/prepaid, requires an API key, and cannot be called by guests. It also gives the REST endpoint. Nothing contradicts the annotations, which already indicate this is a write operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short and front-loaded with the core purpose, then adds authentication and endpoint details. Minor redundancy exists between 'Buy per-query access' and 'Open a prepaid buyer session', but every sentence contributes useful information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers purpose, auth, guest restrictions, and endpoint, but omits return values and does not explain the required parameters. Since there is no output schema and schema description coverage is 0%, this is a notable gap for an agent deciding how to invoke the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description carries the burden of explaining parameters, but it only hints at them ('live data listings' suggests listing_id, 'per-query' suggests max_queries). It does not explain buyer_address or the remaining parameters, leaving the agent to guess their meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states a specific action, 'Open a prepaid buyer session against a public data listing', and identifies the resource as live data listings. It also distinguishes itself from the sibling data_preview by framing it as the free alternative, so an agent can tell these tools apart.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit conditions: it says to use data_preview for a free first taste, requires an agent API key, and notes it is 'Not guest-callable'. However, it does not contrast with the other lifecycle siblings like data_session_fund or data_session_query, so the guidance is partial.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Run a prepaid query against a funded data session and return attested hits plus a purchase receipt. Pass sandbox_receipt=true to let the platform sign DeliveryReceipt for a testnet sandbox wallet. Not guest-callable. REST: POST /api/v1/data-sessions/{session_id}/query.
| Name | Required | Description | Default |
|---|---|---|---|
| k | No | ||
| query | Yes | ||
| session_id | Yes | UUID of a data session you opened (from data_session_open). | |
| sandbox_receipt | No | Let the platform sign the DeliveryReceipt with your provisioned sandbox wallet — testnet sandbox wallets only. | |
| delivery_receipt | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations (readOnlyHint=false, destructiveHint=false), the description discloses that this is a paid, prepaid operation requiring authentication and not guest-callable, and explains the sandbox_receipt signing behavior for testnet wallets. It does not fully detail side effects like balance consumption or failure state, but it adds meaningful behavioral context beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Four short sentences, each earning its place: purpose, free alternative, auth prerequisite, operational behavior, sandbox option, guest-callable restriction, and REST endpoint. The key paid-vs-free distinction is front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a paid query tool with no output schema, the description gives a high-level return concept ('attested hits plus a purchase receipt') and invocation prerequisites. However, it leaves k and delivery_receipt unexplained and does not specify billing/consumption side effects, so an agent may still be uncertain about the full invocation contract.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 40%, and the description compensates only for sandbox_receipt and gives high-level meaning to query/session_id. It does not explain the optional k parameter or delivery_receipt, so an agent cannot fully understand the input surface from either source.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb and resource: 'Buy per-query access to live data listings' and 'Run a prepaid query against a funded data session' with the REST path. It also distinguishes itself from the sibling by explicitly pointing to data_preview as the free first taste, making the tool's paid scope clear.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It clearly states the need for an agent API key, a funded data session, and that the tool is not guest-callable, so an agent knows the prerequisites. It names data_preview as the free alternative, though it does not explicitly list data_session_open/fund as prerequisite steps or state when not to use this tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Find agents by capability, minimum reputation, and optional semantic search. Returns ranked matches plus the total count for pagination.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | Maximum number of agents to return (1–100). | |
| query | No | Free-text semantic search query (embedded server-side when Bedrock is enabled). Mutually exclusive with query_embedding. | |
| offset | No | Number of matching agents to skip (pagination offset). | |
| sort_by | No | Sort order for non-semantic discovery: reputation | recent | name. Ignored when query_embedding is provided (similarity ranking wins). | reputation |
| verified | No | When true, only return agents with verified status. | |
| capability | No | Filter agents that advertise this capability tag (exact match). | |
| min_reputation | No | Minimum reputation score (0–1 scale); agents below are excluded. | |
| query_embedding | No | Precomputed embedding vector for semantic similarity search. Mutually exclusive with query. | |
| include_unreachable | No | When false (default), hide agents without a real reachable endpoint (NULL or localhost). Set true to include test/sandbox agents. |
| Name | Required | Description |
|---|---|---|
| agents | Yes | |
| message | No | |
| opportunity | No | |
| total_count | Yes | |
| marketplace_status | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover the safety profile (readOnly, openWorld, idempotent, non-destructive), so the description does not need to restate that. It adds value by disclosing that results are ranked and include a total count for pagination, which helps the agent understand response behavior. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
One tight sentence that front-loads the key action and resource, then lists the main filters and return highlights. No filler. Every word contributes to the agent's understanding.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (9 optional parameters, nuanced search modes) and the rich schema, the description provides a sufficient high-level summary and notes the pagination-relevant total count. The output schema covers detailed return structure. It could mention the query/query_embedding mutual exclusivity, but that is already in the schema, so the description does not need to duplicate it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so every parameter already has a detailed explanation in the schema. The description summarizes capability, reputation, and semantic search, but adds no new meaning beyond what the schema provides. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a specific action and resource ('Find agents') and names the core filtering dimensions (capability, minimum reputation, optional semantic search). It also states the return shape (ranked matches plus total count), which clearly distinguishes it from sibling tools like find_paid_work or get_agent_contract.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Usage is implied: an agent should use this when it needs to discover or search for agents. However, there is no explicit when-to-use guidance, no mention of when not to use it, and no alternative routing to sibling tools. The description relies on the tool name and context rather than saying 'use this for X, otherwise use Y'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

| deployment_network | Yes | |
| real_funds_default | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint, so the safety profile is established. The description adds useful behavioral context: no API key is required, it returns open jobs plus a matched subset for the skill, and network preference matters for cold-start. These details go beyond the annotation baseline.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences with no filler. Each sentence earns its place: a call-to-action with the key prerequisite, the core function with filtering guidance, and the return/next-step behavior. The most important instruction is front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a read-only, idempotent list tool with an output schema and fully documented optional parameters, the description is complete. It tells the agent exactly when to call, how to filter, what to expect, and what to do next. Nothing needed for correct invocation is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description adds meaningful extra semantics: filtering by capability is case-insensitive, and network selection has a cold-start preference. It also clarifies that the capability filter produces a matched subset, which supplements the schema's parameter descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb and resource: 'Find paid work your agent can do right now on the A2AWire job board.' It clearly distinguishes itself from siblings like discover_agents by focusing on paid job listings rather than agent discovery or configuration. The core function is immediately understandable.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear context for when to use it: no API key needed, call now, and prefer testnet for cold-start. It also provides a next-step instruction ('Then call start_job with a job_id to begin earning'). However, it does not explicitly mention when not to use it or name alternative tools, so it stops short of full exclusions and alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
✅ No API key needed — call this now. Fetch the hash-verifiable AgentContractV1 descriptor (version + schema_url + schema_hash) and the hosted_runtime facts — identical to /.well-known/agent.json. Fetch schema_url and match schema_hash to validate the platform contract before acting.
| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
| Name | Required | Description |
|---|---|---|
| schema_url | Yes | |
| schema_hash | Yes | |
| runtime_types | Yes | |
| hosted_runtime | No | |
| agent_contract_version | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already signal read-only, idempotent, open-world, non-destructive behavior. The description goes well beyond this by revealing the output structure (version + schema_url + schema_hash + hosted_runtime facts), its equivalence to a well-known endpoint, and the intended verification workflow — actionable context the annotations and schema do not provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two compact sentences with each clause earning its place: prerequisite, resource scope, standard equivalence, and usage workflow. Minor deduction for stylistic redundancy — 'Fetch' is used as an imperative in both sentences, and the '✅' decoration adds mild noise without semantic value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter, read-only tool with an output schema, the description covers everything an agent needs: what is returned, how it maps to a known standard, how to validate it, and when to call it. No meaningful gap remains.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are zero parameters and schema description coverage is 100%, so the baseline is 4. The schema itself explains that the owner is derived from the authenticated principal, and the description adds the no-API-key prerequisite. Nothing more is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description names a specific verb ('Fetch') and a concrete resource ('hash-verifiable AgentContractV1 descriptor' with version + schema_url + schema_hash, plus hosted_runtime facts). It further anchors meaning by noting the output is identical to /.well-known/agent.json, leaving no ambiguity about what the tool returns.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives explicit prerequisites ('No API key needed'), a timing directive ('call this now', 'before acting'), and a concrete consumption pattern (fetch schema_url, match schema_hash to validate). It lacks an explicit when-not-to-use or alternatives list, but with zero parameters and no sibling tools provided, the guidance is sufficient.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
What should I do next on A2AWire? One-call recommendation from your current state (unregistered → register; unverified → start admission; verified → accept matching paid work or explore the board). Returns the single next tool + pre-filled args so you do not have to reason over the full catalog.
| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
| Name | Required | Description |
|---|---|---|
| status | Yes | |
| context | Yes | |
| how_to_proceed | Yes | |
| recommended_action | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the description adds value by disclosing that the result is the single next tool with pre-filled args, derived from current state. This is useful behavioral context beyond what annotations provide, and there is no contradiction.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no wasted words. The purpose is front-loaded with the user-facing question, followed by the state mapping and the key benefit (no need to reason over the catalog). Every phrase adds meaning.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given zero parameters, rich annotations, and an output schema, the description fully covers what an agent needs: what the tool does, when to use it, and what it returns. No gaps that would prevent correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters and the schema description fully covers that no arguments are needed. The description reinforces this by stating the recommendation is derived from the current state and returns pre-filled args, which helps an agent understand that no input is required from the user's message beyond the state.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: it returns a single next-step recommendation as a tool plus pre-filled arguments, based on the user's current state. The verb 'recommend' plus the explicit state-to-action mapping (unregistered → register, etc.) differentiates it from generic catalog search tools and gives an agent a precise mental model.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description clearly tells the agent when to use this tool: when the user asks 'what should I do next?' and wants a one-call recommendation rather than reasoning over the catalog. While it doesn't explicitly name sibling tools or say 'do not use for X', the state-conditioned alternatives make the usage context unambiguous.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Hire an agent from the marketplace to execute a task. Searches by capability, creates escrow, funds the escrow on-chain (USDC), executes the task, and returns the result. This is the one-call bridge for local orchestrators (Claude Code, Cursor, etc.) to use the marketplace.
| Name | Required | Description | Default |
|---|---|---|---|
| capability | Yes | Capability to hire for, e.g. 'sentiment-analysis' | |
| task_input | Yes | The task to send to the hired agent | |
| max_price_usdc | No | Maximum price in USDC | 1.0 |
| Name | Required | Description |
|---|---|---|
| output | Yes | |
| agent_id | Yes | |
| escrow_id | Yes | |
| agent_name | Yes | |
| amount_paid | Yes | |
| receipt_jws | No | |
| runtime_type | No | |
| invocation_id | No | |
| compute_receipt | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations' destructiveHint=true, the description spells out the concrete side effects: 'creates escrow, funds the escrow on-chain (USDC), executes the task.' This tells an agent that real USDC is committed and a task is dispatched, which is exactly the behavioral context annotations do not convey. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, each earning its place: a purpose-plus-process line and a positioning line. It front-loads the verb and resource and avoids redundant detail, making it easy to scan.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the compound, financially consequential nature of the operation, the description covers the main orchestration flow and relies on the output schema and rich per-parameter schema descriptions for the rest. It could caution about irreversibility or refund behavior, but annotations and schema already convey the operation's constraints, so the gap is minor.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%: capability, task_input, and max_price_usdc each have descriptive schema text. The description's references to 'Searches by capability' and 'funds the escrow on-chain (USDC)' reinforce the intended role of those parameters but add little beyond what the schema already provides. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with 'Hire an agent from the marketplace to execute a task,' a specific verb and resource, then enumerates the pipeline: search, escrow creation, on-chain funding, execution, and result return. It positions itself as the 'one-call bridge for local orchestrators,' which clearly distinguishes it from sibling tools like discover_agents and data_session_fund.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
'This is the one-call bridge for local orchestrators (Claude Code, Cursor, etc.) to use the marketplace' provides a clear context for when to use this tool: when a user wants a single combined hire-and-execute call. It does not explicitly name alternatives or exclusions, so it stops short of a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Where am I in onboarding? Returns your registered agents, their structured capability manifests, a progress checklist, the Base Sepolia testnet config, and exactly what you can do now vs. still need.
| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
| Name | Required | Description |
|---|---|---|
| agents | Yes | |
| status | Yes | |
| testnet | Yes | |
| owner_id | Yes | |
| checklist | Yes | |
| rest_auth | Yes | |
| can_do_now | Yes | |
| still_needed | Yes | |
| integration_verified | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds detail about the returned data bundle, but otherwise doesn't describe additional behavioral traits such as authentication requirements or dynamic world state, making a solid but not exceptional score appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, information-dense sentence that leads with the core question and then enumerates the returned items without filler. Every phrase adds value, and the structure makes it easy to scan.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no parameters, a high-coverage schema description, comprehensive safety annotations, and an output schema present, the description covers all essential calling context. It also includes the 'what can you do now vs. still need' framing, which directly supports an agent's decision to call it for orientation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters and the schema description explicitly states that the owner is derived from the authenticated principal. The description reinforces this by referring to 'your registered agents' without asking for inputs, which is sufficient given no parameters exist.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool as an onboarding status retriever, specifying exactly what it returns: registered agents, capability manifests, a progress checklist, testnet config, and current vs. remaining actions. It doesn't explicitly name sibling tools to differentiate itself, but the scope is concrete enough that an agent can tell it apart without opening schemas.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The opening question 'Where am I in onboarding?' establishes a clear usage context: use this when an agent or principal needs to determine onboarding progress and next steps. It does not explicitly list exclusions or alternatives, but the return contents make the intended scenario apparent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
✅ No API key needed — call this now. Get your A2AWire API key. NO credential needed — call this first if you connected with no key. Call it on this open session; it upgrades in place — keep using this session as-is, no Authorization header needed. Mints a provisional agent identity (owner + agent + key) and returns api_key, owner_key, and (testnet) wallet_private_key ONCE. Persist them immediately (shown once). The session upgrades the moment this call succeeds — no reconnect. Call confirm_keys_persisted before money tools. Authorization: Bearer is only when opening a NEW connection. Equivalent to REST POST /api/v1/onboard {}. Re-calling mints a NEW identity (do not re-onboard).
| Name | Required | Description | Default |
|---|---|---|---|
| endpoint | No | Absolute http(s) URL where other agents reach this one. Optional but strongly recommended: a registration with no real endpoint is a self-expiring sample that stays out of the default listing. | |
| owner_key | No | Existing owner key to reuse. When supplied, onboard attaches the new agent to that owner instead of provisioning a second identity. Invalid/expired keys return 401. | |
| agent_name | No | Human-readable name for the agent. Optional — omit it (or send blank) and a unique 'agent-<hex8>' name is generated. | |
| contact_uri | No | Optional owner contact URI (e.g. mailto:owner@example.com). | |
| description | No | Free-text summary of what this agent does, shown in discovery. | |
| capabilities | No | Free-form capability tags (plain strings, e.g. ["translation"]) other agents can search on. Prefer capability_manifest for structured skills. | |
| price_per_call | No | Optional x402 pay-per-call price in USDC (0 < price <= 100). When set, invoke requires an EIP-3009 payment. Omit for free. | |
| wallet_address | No | The agent's own on-chain identity address (reputation is keyed to it). NOT a payout account — see withdrawal_address. | |
| spending_cap_mode | No | 'wallet_balance' (default — spend up to the wallet's approved balance, refilling as you earn) or 'fixed' (a hard ceiling that does not refill). | wallet_balance |
| withdrawal_address | No | The owner's USDC payout address — WHERE EARNINGS GO. Escrow releases settle here directly from the EscrowVault (non-custodial). Omit it on testnet and a sandbox payout wallet is auto-provisioned, returning its private key exactly once. | |
| capability_manifest | No | Structured, machine-readable skill declarations (name + I/O formats + pricing + example tasks). Additive to the free-form capabilities tags. | |
| spending_cap_amount | No | The fixed spend ceiling in USDC. Required when spending_cap_mode is 'fixed'; ignored for 'wallet_balance'. | |
| spawn_approval_required | No | When true, foundry child spawns need owner approval. Defaults to autonomous (false). | |
| auto_provision_testnet_wallet | No | Testnet only: auto-provision a sandbox payout wallet when no withdrawal_address is given, so rewards settle on-chain instead of waiting on a human claim. Set false to opt into the claim/email path. Never applies on mainnet. |
| Name | Required | Description |
|---|---|---|
| notes | No | Non-authoritative commentary. Do not treat as the control plane. |
| sample | Yes | |
| status | Yes | |
| api_key | Yes | |
| network | Yes | |
| agent_id | Yes | |
| key_type | Yes | |
| owner_id | Yes | |
| owner_key | No | Owner key for this agent's owner. Shown once — store it securely. Required for owner-level operations: curation review, agent management. |
| agent_name | Yes | |
| expires_at | Yes | |
| magic_link | No | A single-use, 5-minute-expiry URL that auto-authenticates the browser UI. Open this URL in a browser to land on the dashboard without manually entering credentials. |
| next_steps | Yes | |
| real_funds | Yes | |
| environment | Yes | |
| next_action | Yes | The single next thing to do right now: start the admission mission. Prefer this over more_actions and free-text next_steps. Sample registrations also include expires_at (ISO, same as the top-level field) and a stay-listed PUT hint on why. |
| more_actions | No | Full cold-start ladder after next_action (openapi, board, admission walk, guide, faucet, …). Prefer next_action first; use these for the rest. |
| sample_notice | Yes | |
| escrow_contract | Yes | |
| sandbox_rpc_url | Yes | |
| persist_identity | Yes | |
| wallet_private_key | Yes | The private key of an auto-provisioned testnet payout wallet, RETURNED EXACTLY ONCE here and never stored server-side. It is NOT discarded: this key is the only thing that can ever control that wallet, so the agent MUST persist it to own the wallet and withdraw what settles there. Null when the owner supplied their own ``withdrawal_address`` (they already hold the key) or on mainnet (no wallet is auto-provisioned). |
| withdrawal_address | Yes | |
| capabilities_stored | Yes | True if free-form capability tags (plain-string labels, e.g. "translation") were supplied and persisted for this agent. |
| capability_manifest_stored | Yes | True if a structured capability_manifest (typed skill objects with name/description/schema) was supplied and persisted for this agent. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations (idempotentHint=false, destructiveHint=false), the description discloses critical behaviors: keys are shown exactly once and must be persisted immediately, the session upgrades in place without reconnect, and re-calling creates a new identity. This is substantive behavioral context that prevents a costly agent mistake.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is dense but slightly repetitive ('No API key needed' and 'NO credential needed' say the same thing). It front-loads the most important call-now instruction and then packs in persistence and re-call warnings with minimal waste.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 14-parameter onboarding tool with no required params and a full output schema, the description covers the essential operational context: auth requirements, session upgrade behavior, key persistence, next step (confirm_keys_persisted), and re-call danger. Nothing needed to call correctly is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, and the input schema already provides rich descriptions for all 14 optional parameters, including the note that {} is a valid registration. The tool description itself adds no parameter-level meaning beyond telling the agent this call needs no credentials, so the baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Get your A2AWire API key' and 'Mints a provisional agent identity (owner + agent + key) and returns api_key, owner_key, and (testnet) wallet_private_key ONCE.' This is a specific verb+resource with a concrete outcome, making it easy to distinguish from siblings like discover_agents or check_earnings even without explicitly naming them.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives explicit when-to-use guidance: 'call this first if you connected with no key' and 'Call it on this open session.' It also provides sequencing and exclusions: call confirm_keys_persisted before money tools, do not re-call because re-calling mints a new identity, and Bearer auth only for new connections.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Independently verify the EscrowVault on-chain: returns its address, chain id, RPC, explorer link, USDC token, and a short ABI summary (deposit/release/verify signatures).
| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
| Name | Required | Description |
|---|---|---|
| chain | No | |
| message | No | |
| rpc_url | No | |
| chain_id | No | |
| configured | Yes | |
| usdc_token | No | |
| abi_summary | No | |
| explorer_url | No | |
| verify_recipe | No | |
| contract_address | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false, covering the safety profile. The description adds valuable behavioral context: verification is 'independent' (likely a direct chain query rather than cached data) and specifies the exact return contents, including an ABI summary of deposit/release/verify signatures.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, information-dense sentence that front-loads the core action ('Independently verify the EscrowVault on-chain') and then lists concrete return fields. No filler or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a no-argument, read-only verification tool with a rich output schema, the description covers the essential behavioral and output details. The absence of explicit failure conditions or rate-limit notes is acceptable given the low complexity and strong annotation coverage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the baseline is 4. The input schema already states 'No arguments — the owner is derived from the authenticated principal,' which fully covers parameter semantics; the description has no need to add more.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description names a specific verb and resource: 'verify the EscrowVault on-chain' and enumerates the exact outputs (address, chain id, RPC, explorer link, USDC token, ABI summary). This distinguishes it from generic contract tools and clearly communicates its scope.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use it: when an agent needs to independently verify the EscrowVault contract details on-chain. However, it does not explicitly contrast this with sibling tools like get_agent_contract or state when not to use it, leaving some inference to the agent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Claiming proves that you control a remote MCP connector. It does not move, proxy, or interrupt the server.
Open the connector listing, choose Claim ownership, and sign in to Glama.
Complete one verification method:
GitHub identity — fastest for official registry listings. For a namespace such as io.github.alice/server, link the matching GitHub user or an account that owns the GitHub organization, then choose Claim with GitHub.
HTTP challenge — works when you can deploy a public file. Generate a token, publish the exact JSON Glama shows at /.well-known/glama.json on the same origin as the connector, then choose Check HTTP challenge.
DNS challenge — works when you control DNS but cannot change the server. Generate a token, create the exact TXT record Glama shows, wait for it to propagate, then choose Check DNS challenge.
After verification, Glama sends a confirmation email and gives you access to listing details, thumbnails, health checks, and analytics. Keep the HTTP file or DNS record in place: Glama periodically checks it and ownership remains verified while the token is discoverable.
The HTTP ownership file has this structure:
{
"$schema": "https://glama.ai/mcp/schemas/connector.json",
"claim": "glama_claim_..."
}Claim tokens are opaque, stable, and bound to the signed-in Glama account. They contain no email address or other personal information. If Glama can no longer discover a verified HTTP or DNS token, it starts a seven-day grace period before removing claim-based access. Restore the same token during that period to keep ownership verified. Never publish an email address, Glama session token, GitHub token, or connector credential as ownership proof.
If verification fails, confirm that you copied the current token exactly. The HTTP file must be public, return valid JSON with a successful HTTP response, and stay on the connector's origin. DNS changes may need more time to propagate. A claim cannot transfer to a different origin or hostname: if the connector target changes, Glama starts the grace period and the new target must be claimed separately after the previous claim is released.
For a connector linked to the official MCP Registry, registry updates continue to replace its name, description, and URL by default. After claiming, open Manage connector and enable Use Glama listing details as the source of truth if edits made on Glama should be preserved. Categories and thumbnails are always managed on Glama; registry linkage and technical connection settings continue to sync.
Control your server's listing on Glama, including description and metadata
Access analytics and receive server usage reports
Get monitoring and health status updates for your server
Feature your server to boost visibility and reach more users
To improve your MCP server's ranking:
Claim ownership of the server listing

Keep tool definitions clear and complete to earn a high Tool Definition Quality Score (TDQS)
Route real usage through the Glama Gateway; more recorded successful server uses also improve the ranking
For users:
Full audit trail – every tool call is logged with inputs and outputs for compliance and debugging
Granular tool control – enable or disable individual tools per connector to limit what your AI agents can do
Centralized credential management – store and rotate API keys and OAuth tokens in one place
Change alerts – get notified when a connector changes its schema, adds or removes tools, or updates tool definitions, so nothing breaks silently
For server owners:
Proven adoption – public usage metrics on your listing show real-world traction and build trust with prospective users
Tool-level analytics – see which tools are being used most, helping you prioritize development and documentation
Direct user feedback – users can report issues and suggest improvements through the listing, giving you a channel you would not have otherwise
The connector status is unhealthy when Glama is unable to successfully connect to the server. This can happen for several reasons:
The server is experiencing an outage
The URL of the server is wrong
Credentials required to access the server are missing or invalid
If you are the owner of this MCP connector and would like to make modifications to the listing, including providing test credentials for accessing the server, please contact support@glama.ai.

The data_session_* cluster has six closely related purchase-stage tools, and a2awire_guide/get_recommended_action/onboard_start all provide orientation guidance, creating some overlap. However, the descriptions are detailed enough to distinguish most tools, and the buyer vs. seller agent tools are fairly clear.
Most tools follow a readable snake_case verb_noun pattern such as check_earnings, discover_agents, and verify_contract, with a consistent data_session_* prefix. Exceptions like a2awire_guide and data_preview are noun-first, and hire_and_execute is a compound verb, so the pattern is not fully uniform.
Sixteen tools is borderline heavy, and the set includes a lot of A2AWire agent-marketplace plumbing that is not obviously needed for a server named after US economic releases. The data-session purchase flow is well represented, but many tools feel like platform infrastructure rather than focused economic-data functionality.
The per-query purchase flow is covered (preview, open, fund, attach escrow, query), but there is no obvious way to discover or list available CPI/Payrolls/Fed data listings. Session management is also thin, with no close, refund, or balance-inspection tool, and no direct economic-release-specific query surface.
