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

With no annotations, the description carries the full behavior-disclosure burden. It adds useful scoping by noting the catalog is 'bundled' and 'publicly documented,' implying a read-only search over a local catalog. But it does not disclose how search matching works, whether results are paginated, or what the availability parameter accepts, though nothing in the description is misleading.

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, tightly written sentence that front-loads the verb and resource without filler. Every word contributes to conveying the tool's purpose.

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?

Although an output schema exists, the description omits parameter semantics and any usage context that would help an agent decide when to call this tool. The bundled-catalog scope is useful, but with three undocumented parameters and many closely related siblings, the description is not sufficient for reliable invocation.

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 0% and the description does not compensate for this gap. None of the three parameters (limit, query, availability) is explained beyond its JSON type and default; the meaning of the availability parameter and how the query is matched are entirely undefined, so an agent cannot reliably determine correct inputs.

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 action ('Search') and a clear resource ('bundled catalog of publicly documented MCP servers and ecosystems'), which makes the tool's purpose obvious. It is distinct from generic siblings like recipes_mcp_server_get, but it does not explicitly name or differentiate against siblings, so it falls just short of a 5.

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 phrase 'bundled catalog' implies this tool is for searching the built-in/registered MCP server catalog, providing an implicit usage context. However, there is no explicit guidance about when to prefer this over related alternatives such as recipes_mcp_server_get, recipes_list, or recipes_upstream_servers, and no 'when not to use' guidance.

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