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

Annotations already declare readOnly/idempotent/non-destructive and closed-world, so safety is covered. The description still adds real behavioral context: per-role effective tool counts are null when the server runs inside the sandbox and the role gets every exposed tool, credential fields are returned as NAMES and never values, and configStatus reports whether the file could be read.

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?

One long but well-ordered sentence that front-loads the resource and then enumerates the returned binding fields; the null-case and never-values notes are embedded where they matter. Slightly dense, but nothing is wasted and no boilerplate is present.

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?

With no output schema, the description must characterize the return value, and it does so field-by-field (enabled roles, transport, status, approved tools, per-role tool counts, credential field names, configStatus). Safety is covered by annotations and the single parameter by the schema, so nothing an agent needs to call it correctly is missing.

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?

There is a single parameter at 100% schema description coverage ('Project id, e.g. from list_projects'), so the schema carries the semantics. The description adds nothing about projectId (no format, no source beyond the schema), which is the expected baseline when coverage is complete.

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?

States a specific verb and resource ('The MCP servers a project's repository declares in its MCP file (.mcp.json by default)') and enumerates the binding detail returned, so the agent knows exactly what this retrieves. It does not differentiate itself from the sibling list_mcp_bindings, but the scope (config-file declared servers for one project) is otherwise unambiguous.

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?

No when-to-use, when-not, or alternative is named. With list_mcp_bindings, bind_mcp_server, unbind_mcp_server and refresh_mcp_server_tools in the sibling set, an agent gets no help deciding between reading declared config versus listing bindings. Usage is only faintly implied by the word 'declares'.

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