Azure DevOps MCP Server with PAT Authentication

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

With no annotations provided, the description carries full burden for behavioral disclosure but offers minimal information. It doesn't describe what the search returns (e.g., file matches, line numbers), pagination behavior (though schema has skip/top), authentication requirements, rate limits, or whether it's read-only (implied but not stated). The description lacks essential context for a search 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?

The description is a single, efficient sentence that states the core purpose without waste. It's appropriately sized for a search tool, though it could be slightly more informative given the lack of annotations. Every word earns its place, making it front-loaded and clear.

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 complexity of an 8-parameter search tool with no annotations and no output schema, the description is insufficient. It doesn't explain what the search returns (e.g., code snippets, file paths), how results are structured, or any behavioral traits like performance or limitations. For a tool with rich filtering options, more context is needed.

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?

Schema description coverage is 100%, so the schema already documents all 8 parameters thoroughly. The description adds no additional parameter semantics beyond implying 'searchText' is required. With high schema coverage, the baseline of 3 is appropriate as the description doesn't compensate but doesn't need to.

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 action ('Search') and target resource ('Azure DevOps Repositories') with the scope ('for a given search text'). It distinguishes from siblings like 'search_wiki' and 'search_workitem' by specifying code repositories. However, it doesn't explicitly differentiate from 'repo_search_commits' which searches commits rather than code content.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention when to choose this over 'search_wiki' or 'search_workitem', nor does it indicate any prerequisites, constraints, or typical use cases for code searching versus other repository operations.

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