Gitopia MCP Server

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

With no annotations provided, the description carries the full disclosure burden. It adds valuable context about the fetch method ('via the git server gateway') and return format ('raw file content as text'), but lacks information about authentication requirements, error handling, file size limits, or rate limiting that would be necessary for a robust mutation-free read operation.

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?

Four sentences, each serving a distinct purpose: use case with differentiator, implementation mechanism, required inputs, and return value/alternative reference. No redundant or wasted words; information is front-loaded with the use case.

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?

Without an output schema, the description adequately explains the return value ('raw file content as text'). However, with zero schema coverage on four parameters and no annotations, the description should have provided more detail on parameter meanings and usage constraints. It meets minimum viability but leaves significant gaps for a remote Git operation tool.

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 schema has 0% description coverage (no parameter descriptions), and while the description lists the four required parameters by name, it fails to explain their semantics (e.g., whether 'owner' refers to a user or organization, or that 'name' refers to the repository name). It acknowledges their existence but doesn't compensate for the schema's lack of documentation.

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 reads a file from a remote Gitopia repository and includes the specific differentiator 'without cloning it first,' which distinguishes it from the git_clone sibling tool. Uses specific verbs (read, fetches) and identifies the exact resource (remote repository file).

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?

Explicitly states when to use ('when you need to read a file... without cloning it first') and references the specific alternative tool ('See also: git_clone'), providing clear decision criteria for tool selection vs. the sibling clone operation.

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