SnapAPI MCP Server

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

No annotations provided, so description carries full disclosure burden. Successfully mentions return values ('Returns the API status and current server time') and validation purpose. Could enhance by explicitly stating idempotency or safety for repeated calls, but covers core behavioral traits well for a simple health check.

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 tightly constructed sentences: purpose, return values, and usage guidance. Front-loaded with action verb 'Check'. Zero redundancy or waste.

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?

Complete for a zero-parameter health check tool. Addresses purpose, returns, and usage context without requiring output schema elaboration. Sufficient complexity coverage given simple schema and lack of annotations.

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?

Zero parameters present, establishing baseline of 4. Description appropriately makes no parameter claims since schema confirms no inputs required.

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?

Specific verb 'Check' with clear resources (SnapAPI service, API key) and scope (reachability, validity). Distinguishes from operational siblings (analyze, extract, etc.) by positioning as a configuration verification tool rather than a data processing operation.

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?

Explicit when-to-use guidance: 'Use this to verify your configuration before making other calls.' Provides clear temporal context for invocation. Does not explicitly name alternative tools or 'when-not-to-use' exclusions, hence not a 5.

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