MetaMCP Admin MCP

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

No annotations provided, so description carries full disclosure burden. States read operation ('List') but omits return format (full objects vs summaries), pagination behavior, rate limits, or auth requirements. Minimal behavioral context for a tool returning potentially large datasets.

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?

Single sentence, 8 words, front-loaded with action verb. Zero redundancy or filler. Every word earns its place with precise technical terminology.

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?

Adequate for low-complexity tool (1 optional parameter, flat schema). 'MetaMCP' provides domain context. Minor gap: no output schema exists, could briefly hint at return value structure (list of server objects).

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 100% (instance parameter fully documented), establishing baseline 3. Description mentions 'MetaMCP instance' reinforcing the parameter domain but adds no syntax details, format constraints, or examples beyond 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?

Description provides specific verb (List) + resource (MCP servers) + scope (all, on a MetaMCP instance). Clearly distinguishes from sibling 'get_server' (singular retrieval) and 'list_instances' (different resource type) through precise wording.

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 word 'all' implies bulk enumeration use case, distinguishing from 'get_server', but lacks explicit when-to-use guidance or named alternatives. No mention of when the 'instance' parameter is required despite it being conditionally optional.

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