A3.6/5.0
Behavior3/5

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

Annotations indicate readOnlyHint=false, destructiveHint=false, and idempotentHint=true. The description does not contradict these and adds a behavioral note about including the conversation array for reproduction. It does not describe side effects (e.g., where the bug report goes), rate limits, or auth requirements, but with annotations covering the safety profile and idempotency, the description adds sufficient context beyond the structured data.

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 two sentences, concise, and front-loaded with the primary purpose. The first sentence states the core functionality, and the second adds a critical usage detail. No filler or redundant information is present; every sentence earns its place.

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?

The tool is simple (3 parameters, no output schema, no nested objects). The description covers the main purpose and one important parameter (conversation), but it lacks explanation of the 'message' parameter (required) and 'context', and it does not describe what the tool returns or potential error conditions. For a feedback tool, this might be sufficient, but it leaves gaps in comprehension for an AI agent.

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 for parameter explanations. It mentions the 'conversation' parameter explicitly, advising to include recent messages for reproduction. However, it does not explain the required 'message' parameter or the 'context' parameter. The description adds meaning only to one of the three parameters and leaves the others undefined, which is inadequate given zero schema coverage.

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 clearly states the tool's purpose: 'Report a bug, missing feature, or send feedback.' It uses a specific verb ('report') and identifies the resource (bug/feature/feedback). None of the sibling tools (authenticate, connect, marketplace, etc.) overlap with this purpose, so it is well differentiated.

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

Usage Guidelines3/5

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

The description provides a concrete usage instruction: 'Include the conversation array with recent messages for reproduction.' However, it does not explicitly state when to use this tool versus alternatives, though no obvious alternatives exist among the siblings. The guidance is implied rather than explicit, and no exclusions or conditions are given.

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

A3.9/5.0
Disambiguation4/5

Most tools have clearly distinct responsibilities, and the certidão query is fully separated from platform operations. The only real ambiguity is between connect and toolkit_info, which both report status/connection-related information, and marketplace overlaps slightly by offering many internal management actions.

Naming Consistency3/5

The utility names are generally predictable short verbs or noun phrases, but the style is mixed. marketplace is a bare noun, toolkit_info uses an underscore pattern, and mpt_ce_cnf_consultar switches to a Portuguese domain-specific convention, so no single naming rule holds across the set.

Tool Count4/5

Seven tools is a reasonable total for a small MCP server and does not feel bloated. However, most of the tools are platform/admin utilities, with only one domain-specific certidão operation, so the count slightly over-represents the actual MPT CE capability.

Completeness4/5

For a read-only Brazilian official certificate lookup, mpt_ce_cnf_consultar is the core operation and the surrounding tools cover auth, connection, payment, and feedback. Minor gaps exist, such as query history or explicit certificate-file download, but an agent can complete the essential workflow.
