Literature MCP Health

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

No annotations provided, so description carries full burden. It states the tool returns data, implying a read-only, non-destructive operation, but does not explicitly disclose safety, permissions, or side effects. Basic transparency is present but not enhanced.

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, no wasted words, front-loaded with purpose. Perfectly concise.

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 zero-parameter tool with no output schema, the description is nearly complete. It could mention that the tool is for health checks or diagnostics, but the current text covers the core purpose. Slight lack of detail on response format is acceptable given 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?

No parameters in schema, so schema coverage is 100%. Baseline 4 is appropriate as description adds no parameter info but is not required to. The mention of 'configured optional API keys' gives context about the data returned.

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 returns server metadata and optional API keys. The verb 'Return' and resource 'server metadata and configured optional API keys' are specific and distinct from siblings like 'discover_papers' or 'export_to_zotero'.

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 implies usage for inspecting server configuration, but no explicit guidance on when to use versus siblings or when not to use. No exclusions or alternatives mentioned.

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