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. While 'List' implies a read-only operation, the description omits return format, pagination behavior, caching, or any side effects. It does not disclose what constitutes a 'configured' instance versus other states.

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 concise at six words. Front-loaded with the verb 'List', no filler content, and appropriately sized for a parameter-less tool. 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?

No output schema is provided, yet the description does not compensate by describing the return structure, fields, or what distinguishes an instance object. Without annotations or parameter complexity to document, the description should explain the output format but doesn't.

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?

The input schema contains zero parameters, which sets a baseline score of 4. The description appropriately does not invent parameters that don't exist in the schema.

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 the action ('List') and resource ('MetaMCP instances') clearly, but fails to differentiate what an 'instance' is versus siblings like 'list_servers', 'list_namespaces', or 'list_endpoints'. In a namespace crowded with list operations, this distinction is necessary for correct selection.

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 guidance provided on when to use this tool versus the numerous sibling list tools (list_servers, list_namespaces, etc.). No prerequisites, filtering options, or contextual triggers are mentioned.

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