util_mcp_server_readiness_report

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

No annotations are provided, and the description only says 'score an MCP server'. It does not disclose behavioral traits such as whether the tool performs any destructive actions, requires authentication, has rate limits, or accesses external resources. The reader has no idea about side effects or prerequisites. For a tool with zero annotation coverage, this is insufficient.

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 sentence, which is concise. However, it is too brief for the complexity of the tool, missing essential details. While front-loaded with the purpose, it sacrifices clarity for brevity. It earns a 3 because it is not verbose but lacks necessary structure for a complete definition.

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 (scoring a server on multiple criteria) and the lack of output schema, parameter details, or annotations, the description is highly incomplete. It does not explain the scoring methodology, return format, or how to specify the server. Even for a simple tool, this level of detail is insufficient for an agent to use it correctly without guessing.

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 a single parameter 'arguments' of type object with additionalProperties true, and schema description coverage is 0%. The description does not clarify what properties the arguments object should contain, despite the tool needing a server target. The parameter semantics are completely opaque, forcing the agent to guess or rely on external documentation. This is a critical gap.

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: to score an MCP server on specific criteria (initialize, tools/list, schema hygiene, manifest discovery, agent usability). The verb 'score' and the resource 'MCP server' are specific, and it distinguishes itself from sibling tools like util_api_health_report which target different domains. However, the description does not elaborate on what 'score' means, leaving some ambiguity about the output format.

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?

There is no guidance on when to use this tool versus alternatives. The description does not mention prerequisites, ideal context, or when not to use it. As a specialized report tool, some context like 'Use this when evaluating an MCP server's setup' is implied but not stated, and no comparative guidance against similar utilities (e.g., util_api_health_report) is provided.

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