MetaMCP Admin MCP

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It fails to mention safety (read-only vs destructive), pagination behavior, or what the return payload contains (e.g., endpoint configurations, URLs, status).

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?

Extremely brief single sentence with no wasted words. However, given the lack of annotations and output schema, the extreme brevity leaves significant informational gaps rather than exhibiting disciplined conciseness.

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?

inadequate for a tool with no annotations, no output schema, and operating within a complex API surface (16+ sibling tools). It does not explain what constitutes an 'endpoint' in this context, its relationship to instances/namespaces, or the structure of returned data.

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?

Input schema has 100% description coverage for the single 'instance' parameter ('Instance name'). The description adds no additional parameter semantics (e.g., optional vs required behavior, format constraints), meeting the baseline score.

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?

Clear verb (List) + resource (endpoints) + scope (all on a MetaMCP instance). However, it does not explicitly differentiate from the sibling 'get_endpoint' tool or clarify when to enumerate vs. retrieve a specific endpoint.

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?

Provides no guidance on when to use this tool versus alternatives like 'get_endpoint' or 'list_instances', and does not mention prerequisites such as requiring a valid instance name.

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