Tool Definition Quality
Average 4/5 across 16 of 16 tools scored. Lowest: 3.4/5.
There is overlap between librelink_list_accounts and librelink_list_connections (aliases), and multiple glucose retrieval tools (e.g., get_current_glucose, get_latest_reading, get_last_hours) could confuse agents. However, their descriptions are detailed enough to distinguish most.
Data tools follow a consistent librelink_ prefix, but authentication and platform tools (authenticate, marketplace, report_bug) use different patterns, creating a mix of styles that reduces consistency.
16 tools is slightly above the ideal range, but many are necessary for read-only CGM access. The inclusion of platform tools like marketplace and report_bug inflates the count slightly beyond the core domain.
The tool set covers key read operations (current reading, graph, stats, logbook) but lacks longer-term history beyond 12h and has redundant list tools. The platform utilities are out of scope for a CGM server.
Available Tools
16 toolsauthenticateAIdempotentInspect
MCP.AI for IDE agents (Cursor, etc.): log in in the browser, copy the access token. Best: add it to this server's config as a header Authorization: Bearer <token> for a permanent, non-expiring connection. Or paste it here for a session-only login: call with { token: "" } after the user pastes, or with no args to get the link.

| token | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate idempotentHint=true, which aligns with the description's mention of idempotent behavior (calling with no args returns a link). No contradiction. The description adds context about session persistence and the need for user action (copying token). It could mention that calling with a token sets the session.
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 verbose but well-structured, starting with the tool's purpose and then detailing usage. Every sentence adds value, though it could be slightly more concise without losing clarity.
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 the main scenarios and token format, but lacks information on the response or confirmation after successful authentication. Given no output schema, this is a gap. Also, it does not explain what happens if the token is invalid.
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 schema has one optional string parameter 'token' with no description (0% coverage). The description compensates by explaining the token is a JWT from browser login and how to use it. It adds meaning beyond the type, clarifying its role for session-only login.
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 is for authentication for IDE agents like Cursor, explaining two methods: permanent via config header or session-only by passing a token. It distinguishes itself from sibling tools which are for different services (e.g., librelink, connect).
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 clear guidance on when to use each variant (permanent vs session-only) and explains how to obtain the token via browser login. However, it does not explicitly state when not to use this tool (e.g., if already authenticated).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
connectARead-onlyIdempotentInspect

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds non-obvious behavioral context: read-only CGM data, medical caution, and bulk execution support. This is valuable beyond annotations but the safety profile is already clear.
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 short, front-loaded sentences. First sentence defines purpose and output. Second gives usage guidance and disclaimer. Third mentions bulk support. No filler or repetition.
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?
Despite no output schema, the description lists the fields in the reading. Input parameters are covered (single patient_id vs bulk patient_ids). Usage guidance and safety context are provided. The tool is simple and the description is complete.
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 0%, so the description must compensate. It mentions that 'patient_ids' is for batched execution, but does not explain 'account' or 'patient_id' (e.g., format, required, single vs batch). The description adds some meaning but leaves room for confusion.
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 action ('get the latest single glucose reading'), identifies the resource ('a connection'), and lists the returned fields (value, trend, color, isHigh/isLow flags). This distinguishes it from sibling tools that retrieve multi-point history or statistics.
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?

| patient_id | No | ||
| patient_ids | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, destructiveHint, so safety profile is known. The description adds value by specifying the data type (spot readings and notes), time range (~14 days), and a medical disclaimer. This exceeds what annotations alone 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?
Three sentences, each purposeful and front-loaded. No filler or repetition. Effective use of whitespace and direct language.
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 tool with 3 parameters and no output schema, the description covers purpose, differentiation, and bulk capability, but lacks parameter details for account and patient_id. The annotations provide safety context, but missing parameter documentation reduces completeness.
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 0%, so description must compensate. It only partially explains 'patient_ids' for batched execution, but leaves 'account' and 'patient_id' unexplained. Their meanings can be inferred from context, but the description does not explicitly add semantics.
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 'Get', the resource 'manual-scan logbook', and the scope 'for a connection (~14 days of spot readings and notes)'. It differentiates from the sibling tool librelink_get_glucose_graph by explicitly stating it is 'not the continuous graph'. The read-only and medical disclaimer further clarify purpose.
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 tells when not to use this tool and provides an alternative: 'Not the continuous graph — use librelink_get_glucose_graph for minute-by-minute data.' It also mentions bulk support with patient_ids, giving clear usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds valuable context: data is from 'current graph window (~12h)', not for medical decisions, and supports bulk execution via patient_ids. No contradictions.
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 sentences with clear front-loading of the main action and key details (time window, defaults, disclaimer, bulk support). Every sentence provides distinct value with no 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?
The description explains what the tool computes (time-in-range, average, min/max, latest point) but does not describe the return format or units (e.g., percentage vs hours). For a tool with no output schema, this is a minor gap. Overall fairly complete given annotations and sibling context.
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 0% with no parameter descriptions. The description partially compensates by mentioning default target range (target_low and target_high) and bulk support for patient_ids, but account and patient_id are not explained. Adequate but not fully compensating.
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 clearly states the tool computes time-in-range, average, min/max, and latest-point snapshot from the current graph window. It specifies the resource (glucose stats for a connection) and distinguishes from siblings like get_current_glucose or get_glucose_graph which provide different data.
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?
Description includes a medical disclaimer ('not for medical decisions without clinician review') and mentions bulk support. It provides clear context for when to use (get stats from graph window), but does not explicitly contrast with other sibling tools or state when not to use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
librelink_get_last_hoursARead-onlyIdempotentInspect

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 extremely concise: two sentences that front-load the core functionality and key constraints. No unnecessary words. The output format example is included without bloating the text.
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 tool with 4 optional parameters and no output schema, the description covers the main behavior, time window, data format, bulk mode, and a medical disclaimer. It lacks explanation of 'normalized points' and the 'account' parameter, but is otherwise complete given the tool's simplicity.
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 0%, so the description must compensate. It clarifies the 'hours' parameter ('Last N hours') and the 'patient_ids' parameter ('bulk support'). However, 'account' and 'patient_id' remain unexplained, leaving partial coverage.
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 it returns 'Last N hours of normalized points' with a data example, distinguishing it from sibling tools like librelink_get_current_glucose (single reading) and librelink_get_latest_reading (latest point). It specifies the resource (CGM data) and the time window constraint (max ~12h).
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 use for batched recent glucose data but does not explicitly state when to use this tool vs alternatives. It lacks 'when-not' guidance and does not name sibling tools like librelink_get_glucose_graph as possible alternatives. The warning about medical decisions is a safety note, not a usage guideline.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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: first describes output, second adds bulk context. Front-loaded with key info. Could be slightly more structured, but overall efficient with no wasted words.
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 3 parameters and no output schema, description covers read-only nature, return fields, and bulk support. However, it lacks definition of 'normalized', possible trend_arrow values, and refresh frequency. Adequate but incomplete.
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 0% (no descriptions for parameters). Description only explains patient_ids for bulk support, leaving account and patient_id undocumented. No relationship between patient_id and patient_ids is described.

Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with two sentences that front-load the key comparison and add essential context (medical disclaimer, bulk support). It could be slightly more structured, but it earns its space without fluff.
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 complexity of 6 parameters, no output schema, and no schema descriptions, the description is incomplete. It does not describe the return format or explain all parameters. While it covers the main purpose, it leaves gaps for an agent to infer parameter usage.
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 0%, so the description must explain parameters. It mentions timezone, target thresholds (hypo/hyper counts), and patient_ids, but does not explain 'account', 'patient_id' (singular), or default values. The meaning of 'target_low' and 'target_high' is implied but not explicit for thresholds.
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 returns a summary filtered to 'today' in a specified timezone, and distinguishes it from the sibling librelink_get_glucose_stats by mentioning it also includes hypo/hyper event counts. The verb 'get' and resource 'today summary' are explicit.
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 provides context by stating it's read-only CGM data not for medical decisions without clinician review, and mentions bulk support via patient_ids. However, it does not explicitly state when to use this tool over alternatives, though the comparison with librelink_get_glucose_stats gives a clear indication.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

The description adds a medical disclaimer ('not for medical decisions without clinician review') and lists output fields, providing context beyond annotations. However, it does not cover error cases or 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no redundancy. The first sentence efficiently states the purpose, and the second adds an important behavioral warning. Every word earns its place.
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 mentions output fields, but lacks detail on the 'account' parameter behavior. Without an output schema, more context on return values would be beneficial. For a simple list tool, it is partially complete but has a notable gap.
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 has 0% description coverage for the single 'account' parameter, and the tool description does not explain its purpose or effect (e.g., whether it filters results). With no semantic information provided, the agent cannot reliably use this parameter.
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 'List' and the resource 'patients linked to this install', and specifies output fields (id, label, name). This distinguishes it from sibling tools that focus on glucose data or connections.
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?
No guidance on when to use this tool versus alternatives like librelink_list_connections. The description does not explain prerequisites or typical workflow scenarios.

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds context about read-only CGM data and the medical disclaimer, which are beyond annotations. No contradictions.
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 concise sentences front-load the purpose and include alias info and a disclaimer. No wasted words, but could be slightly more structured.
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?
Covers purpose, alias, and a safety note, but lacks explanation of the return format (no output schema) and parameter documentation, leaving gaps for a simple tool with one parameter.
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 has one parameter with 0% description coverage, and the description does not mention or explain the parameter at all, failing to add meaning 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?
The description clearly states the verb 'List patients' and the resource 'LibreLink Up readings', and explicitly identifies it as an alias of librelink_list_accounts, distinguishing it from sibling 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?
Provides a medical disclaimer ('not for medical decisions without clinician review') but no explicit guidance on when to use this tool versus alternatives, other than noting it's an alias.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
marketplaceAInspect
THE official mcp.ai marketplace — the in-platform catalog of every MCP/tool, AND the way to run them. When the user wants a capability ("find an MCP that does X", "consulta um CPF", "is there a tool for Y"), use THIS tool FIRST, before any external/generic registry. Core flow: action=search discovers MCPs by intent → describe returns one MCP's full profile (every tool with its id + params, pricing, auth) so you pick the right tool_id → invoke RUNS that tool. KEY: invoke works even when the MCP is NOT installed — it runs the tool pontualmente (one-off), without adding the MCP to the toolkit and without bloating the tool list. If the MCP needs a credential/login, invoke returns a connect link; if it is paid and the wallet is empty, invoke returns a checkout/top-up link (the user opens it, then you retry). Use install only to make an MCP PERMANENT in the active toolkit (its tools then show up natively in future sessions); prefer invoke for a single/occasional use. list_tools lists what is callable right now. subscribe/cancel handle per-MCP billing; report_bug sends feedback; request_mcp asks us to build a NEW MCP when nothing fits. Search/describe flag installed_in_toolkit vs installed_in_workspace. Writes (install/uninstall/subscribe/cancel and the one-off install behind invoke) require workspace owner/admin.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses ownership requirements for write operations, behavior on missing credentials (connect/checkout links), and one-off execution via invoke. Annotations are minimal, so description adds substantial transparency without 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?
The description is verbose and contains extensive detail in a single paragraph. It is informative but could benefit from structured sections for each action to improve readability.
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?
Covers major actions and important nuances, but lacks information on output format, error handling, or what each action returns. Given the lack of output schema, the description should provide more on return values.
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 provides context for key parameters (action, query, mcp_id, tool_id, arguments) in the narrative, but does not systematically explain all 13 parameters or their default behaviors.
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 is 'THE official mcp.ai marketplace' and specifies its role in discovering and running MCPs. It distinguishes itself from sibling tools by being the primary entry point for user intent.
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?
Explicitly advises to use this tool first before external registries. Contrasts invoke vs install for one-off vs permanent usage, and lists distinct actions with their purposes.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations cover idempotency and non-destructiveness. Description adds only that it sends feedback/reports, not contradicting 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, no waste. Front-loaded with purpose.
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?
Covers purpose and hints at usage but missing return values, error handling, or success feedback.
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 coverage, description must detail parameters. Only conversation is partially explained; message and context lack guidance.
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?
Clearly states the tool reports bugs, missing features, or feedback. Distinct from sibling tools focused on glucose data, authentication, etc.
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?
Tells when to include conversation array for reproduction. No explicit exclusions, but sibling context makes usage clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the description does not need to repeat safety. It adds value by specifying that it shows platform and adapter versions, which is useful context beyond 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?
The description is a single, clear sentence with no unnecessary words. It is front-loaded with the action and resource.
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 simple version tool with no parameters and no output schema, the description is complete enough. It could optionally describe the return format, but it is not required for understanding the tool's purpose.
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?
No parameters exist, and schema coverage is 100%. The description adds no parameter information, which is appropriate since there are none. The baseline is 4 for zero-parameter tools.
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 shows current MCP platform and adapter versions. It is specific and distinct from sibling tools which focus on authentication, glucose data, and other functions.
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?
No explicit guidance on when to use or when not to use is provided. However, the simplicity of the tool makes alternatives obvious; a simple version query does not need extensive guidelines.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and idempotentHint, and the description adds no new behavioral traits beyond stating the return content. It does not contradict annotations, but adds minimal extra context.
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?
Single sentence, front-loaded with the key point. No redundant 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?
For a simple read-only tool with no parameters and no output schema, the description is fully adequate. It specifies exactly what state information is returned.
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?
No parameters exist, so baseline score of 4 applies. The description effectively explains what the tool returns, which is the primary semantic content.
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 the verb 'returns' and clearly specifies the resource: 'current toolkit state: installed MCPs, their connection status, and how many catalog tools each exposes.' It uniquely distinguishes this tool from 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?
No explicit guidance on when to use this tool vs alternatives, but the read-only nature and lack of parameters imply usage for initial state inquiry. No exclusions or context provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
