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

No annotations are provided, so the description carries the full burden. 'Return metadata' clearly signals a read-only operation and enumerates the response categories, but it does not explicitly state that it is non-mutating or describe response structure beyond the listed fields. For a simple metadata endpoint this is adequate, though not fully explicit.

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?

A single sentence with no filler; the purpose and the response contents are front-loaded. Every word earns its place.

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?

The tool is simple (no params, no output schema). The description lists the four metadata categories, telling an agent what to expect, though it omits the exact response shape (e.g., JSON object). For an 'about' tool this is nearly complete, but specifying the response format would close a small gap.

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 are zero parameters and an empty object schema, so the baseline is 4. The description lists the metadata categories that will be returned, which is all that is needed; there are no parameter semantics to clarify.

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 states a specific verb ('Return'), a resource ('metadata about this MCP server'), and enumerates the contained fields (version, data source, coverage, tool list). This clearly distinguishes it from the sibling search/get/list tools.

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 makes the use case explicit: retrieve server-level metadata when that information is needed. It does not explicitly contrast with sibling tools or state when not to use it, but the distinction is inferable from the sibling names and the tool's singular purpose.

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