TDQS

A3.9/5.0
Behavior3/5

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

Annotations already indicate readOnlyHint=false (mutating) and idempotentHint=true (safe to repeat). The description adds the useful guidance about including the conversation for reproduction but does not disclose any side effects (e.g., system notifications, rate limits) beyond that. No contradiction found.

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 one concise sentence that front-loads the purpose and provides a key usage hint. No wasted words.

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 the tool has 3 parameters (one required, two with defaults) and no output schema, the description gives enough to get started but omits details about the 'context' parameter and how the 'conversation' string should be formatted (e.g., JSON array vs plain text). It also does not explain what happens after submission, but the low complexity keeps this from being a critical gap.

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 explain parameters. It explicitly mentions message (implicitly) and conversation (and how to use it), but context is unexplained. The description partially compensates but not fully, leaving context ambiguous.

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 is distinct from siblings like authenticate, connect, or show_version, and directly names the action and scope.

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?

It implicitly tells when to use (when reporting issues/feedback) and gives a specific instruction to include the conversation array for reproduction. However, it does not explicitly mention alternatives or when not to use, so it falls 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.

A3.7/5.0
Disambiguation4/5

Each tool has a clear, distinct function, and the descriptions prevent overlap between them. However, the inclusion of six platform-level utilities alongside the single domain-specific tool (pref_mg_uberaba_cnd_consultar) creates a risk that an agent may select the wrong tool if it misinterprets the server's purpose.

Naming Consistency3/5

Naming uses a mix of single-word verbs (authenticate, connect), noun phrases (marketplace, toolkit_info), and a long descriptive snake_case tool (pref_mg_uberaba_cnd_consultar). While all are lowercase and snake_case for multi-word names, the pattern is not uniform in terms of verb/noun structure or granularity.

Tool Count2/5

The server has 7 tools, but only one directly relates to its stated purpose (certidão negativa de débitos). The other six are generic MCP platform utilities (authentication, marketplace, bug reporting, etc.) that seem out of scope, making the set over-weighted with irrelevant tools for the intended domain.

Completeness2/5

For the domain of issuing negative debt certificates, only a single consult operation exists. There are no supporting tools for managing queries, historical lookups, or other lifecycle steps. The platform tools do not contribute to domain coverage, leaving the surface minimal and potentially insufficient for real-world workflows.
