Strava MCP Server

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

No annotations are provided, so the description carries the full burden. It discloses the tool's behavior as returning metadata, which is useful context, but lacks details on potential errors, rate limits, or authentication needs. Since it's a read-only operation with no parameters, the description is adequate but not rich in behavioral traits.

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, efficient sentence that front-loads the key action ('Returns') and resource. It wastes no words and directly communicates the tool's function, making it highly concise and well-structured for quick understanding.

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 low complexity (0 parameters, no annotations, no output schema), the description is complete enough for its purpose. It explains what the tool does without needing to detail parameters or outputs, though it could slightly improve by hinting at use cases. The lack of output schema is not a major issue here.

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 tool has 0 parameters, and schema description coverage is 100%, so no parameter information is needed. The description does not add or need to add parameter semantics, but it appropriately focuses on the tool's purpose without redundancy, meeting the baseline for tools with no parameters.

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 specific verb ('Returns') and resource ('the Strava MCP server version and related metadata'), making the purpose explicit. It distinguishes itself from all sibling tools, which focus on athlete data, activities, segments, or connections, whereas this tool is about server metadata.

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?

The description implies usage context by mentioning 'server version and related metadata,' suggesting it's for checking server status or compatibility. However, it does not explicitly state when to use this tool versus alternatives (e.g., for debugging vs. data retrieval) or provide any exclusions, leaving some ambiguity.

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