Check if an MCP server is verified in the CuratedMCP catalog

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

No annotations; description says it's a quick lookup reporting verification status. Lacks details on error handling, response format, or any side effects. Adequate but minimal.

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?

Two sentences, front-loaded with 'Quick lookup'. Every sentence earns its place—no unnecessary words.

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?

Covers purpose, use case, and parameter. Missing explicit return value description, but for a simple boolean lookup, description is largely complete. Output schema absent reduces burden.

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?

Single parameter nameOrPackage is described in schema; description adds clarifying example (@org/some-mcp-server) and restates acceptable inputs. Adds value 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?

Clear verb ('check'/'report') and resource (verification status in CuratedMCP catalog). Distinguishes from siblings by focusing on quick lookup vs details or search.

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?

States when to use ('right before running an unfamiliar npx MCP server install command'). No explicit when-not-to-use or sibling comparison, but context is clear.

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