Tool DescriptionsA

Average 3.9/5 across 4 of 4 tools scored.

Server CoherenceA
Disambiguation4/5

The four tools are largely distinct: create_publisher starts registration, confirm_publisher completes it, verify_integration checks the integration, and get_integration_guide provides documentation. The only mild overlap is that create_publisher and confirm_publisher both relate to registration, but their roles (initiate vs. complete) are clearly delineated in their descriptions.

Naming Consistency4/5

Three of four tools follow a clear verb_noun pattern (create_publisher, confirm_publisher, verify_integration), while get_integration_guide deviates slightly with a noun-first structure. The inconsistency is minor and all names remain immediately readable and descriptive of their action.

Tool Count4/5

Four tools is on the lean side but reasonable for a focused onboarding/concierge server covering registration, guidance, and verification. It's slightly below the ideal 5-15 range, leaving a bit of room for operations like updating publisher details or checking status, but the scope is coherent.

Completeness3/5

The core lifecycle from registration to verification is covered (create, confirm, verify), with the integration guide as helpful documentation. However, there are notable gaps: no way to view a publisher's status, resend a verification code, update publisher info, or delete/disable a publisher after the fact. Agents working with existing registrations have dead ends.

ParametersJSON Schema

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It discloses return values (publisher_id, api_key, code snippet) but does not discuss error handling, rate limits, or state changes. For a non-destructive confirmation step, this is adequate but not exhaustive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no waste. The purpose is front-loaded, and the return values are listed immediately. Perfectly concise for the information provided.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given an output schema exists, return value details are partially covered. However, parameter semantics are missing, and there is no guidance on prerequisites (e.g., obtaining pending_id from 'create_publisher') or error scenarios. For a 2-param tool with no annotations, more completeness is expected.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate, but it fails to explain the parameters 'pending_id' and 'code' beyond their names. It does not clarify what 'pending_id' refers to or how the code is validated.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Complete') and resource ('publisher registration'), and distinguishes itself from siblings like 'create_publisher' by referencing the emailed code and stating return values (publisher_id, api_key, code snippet).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly indicates this tool is used to complete registration after receiving an emailed code, implying a sequential workflow with 'create_publisher'. However, it does not explicitly state when not to use it or mention alternatives like 'get_integration_guide'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

create_publisherAInspect

Start publisher registration (requires the human's consent — registers their email). Pass server_url (the MCP server's own URL or repo link) when known — it drives the "server URL set" step on the publisher's dashboard, skipping it leaves that step looking incomplete even once real traffic flows. Emails a 6-digit verification code to contact_email; ask the human for the code, then call confirm_publisher(pending_id, code) to receive the API key. This tool does NOT return a publisher_id or api_key — only confirm_publisher does.

server_urlNo
contact_emailYes

ParametersJSON Schema

resultYes
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It discloses key behaviors: it registers the human's email, requires consent, emails a 6-digit verification code to contact_email, and does not return a publisher_id/api_key. It also explains the side effect of server_url on the dashboard server URL set step. This is strong behavioral disclosure for a stateful registration flow.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense and well-structured but every sentence earns its place — no filler. It front-loads the core purpose, then covers the optional param behavior, then the follow-up step, then an explicit negative (what it does NOT return). This is appropriately sized for a tool with a multi-step flow.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a stateful registration tool with no annotations and 3 params at 0% schema coverage, this description is remarkably complete. It explains the workflow, the human-dependency (consent, email code), the follow-up tool call, and the return-value caveat. The output schema exists and the description appropriately leaves return-format details to it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must compensate, and it does. It clarifies the semantics of server_url (drives the server URL set step, pass repo link or MCP URL) and contact_email (receives the verification code). The 'name' parameter is not elaborated, but the main ambiguous ones are well explained, compensating for the zero schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states this starts publisher registration and that it's a multi-step flow requiring confirmation. The verb 'Start' plus 'publisher registration' gives a clear purpose. It doesn't sharply differentiate from siblings by name, but the explicit mention that it requires human consent and the confirmation step via confirm_publisher distinguishes it functionally.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Excellent usage guidance: it explicitly says to pass server_url when known and explains the consequence of skipping it (dashboard step looks incomplete). It also gives explicit sequencing — ask for the email code, then call confirm_publisher(pending_id, code). It even names the sibling tool confirm_publisher and clarifies that this tool does NOT return publisher_id or api_key.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_integration_guideA

Output Schema

ParametersJSON Schema
NameRequiredDescription
resultYes
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations indicate readOnlyHint=true, and description confirms it provides a guide, but no additional behavioral context (e.g., auth needs, rate limits).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded with key information, no superfluous content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With one parameter and an output schema, the description is mostly complete; could mention if guide is a URL or text, but output schema likely covers it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Description adds allowed values for the 'framework' parameter beyond the schema, which only specifies type and default; schema coverage is 0% so this is valuable.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states it provides an exact integration guide for specific stacks, distinguishing it from sibling tools like create_publisher and verify_integration.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use or not use this tool versus alternatives; simply lists possible stack values without context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

verify_integrationA
Read-only
Inspect

Check whether this publisher has produced a slot_served event (integration works). Pass fastmcp_version (e.g. from fastmcp.__version__ or pip show fastmcp) when the integrated server uses FastMCP — it's recorded so version-specific failures are traceable, not required to verify.

ParametersJSON Schema
NameRequiredDescriptionDefault
publisher_idYes
fastmcp_versionNo

Output Schema

ParametersJSON Schema
NameRequiredDescription
resultYes
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description adds useful context about the fastmcp_version purpose ('recorded so version-specific failures are traceable'), which goes beyond the schema. However, the readOnlyHint=true annotation already covers the safety profile, so the added value is moderate. The description doesn't clarify what the return value looks like or what the outcome is when the event hasn't fired, though the presence of an output schema partially mitigates this.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single paragraph with a clear first sentence defining purpose, followed by concise practical guidance on the optional parameter. It's front-loaded with the core function. The parenthetical could arguably be trimmed, but it's genuinely useful and not redundant, so the length is justified.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given there's an output schema (which presumably documents the verification result), the description covers the essential operational aspects: how to obtain fastmcp_version, when it applies, and that it's optional. The tool is relatively simple (2 params, 1 required), and the description addresses the only non-obvious element (the optional version parameter). The lack of explicit exclusion guidance vs. get_integration_guide is a minor gap but not critical for this straightforward check.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must carry the burden of explaining parameters. The description explains fastmcp_version's semantics well (how to obtain it, when to pass it, why it matters). However, publisher_id is only implicitly understood through the description's use of 'this publisher,' and no additional meaning beyond 'a string publisher identifier' is provided. Given zero schema coverage, this is a partial compensation only.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states what the tool does: 'Check whether this publisher has produced a slot_served event (integration works).' It uses a specific verb (check) with a specific resource (publisher's slot_served event) and explains what success means (integration works). While it's clear on its own, it doesn't explicitly distinguish itself from sibling tools like get_integration_guide or confirm_publisher, so some inference is needed to understand the distinction.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explains when to include fastmcp_version ('when the integrated server uses FastMCP') and clarifies it's optional ('not required to verify'). This gives clear practical guidance on parameter usage specific to the integration scenario. However, it doesn't explicitly state when NOT to use this tool versus alternatives like get_integration_guide, leaving the alternative-selection guidance slightly implicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
