MCP OpenAPI Discovery

by Rekl0w

detect_openapi

Detect OpenAPI or Swagger documents from a documentation or API URL and summarize the API structure.

Instructions

Given a docs or API URL, detect the OpenAPI/Swagger document behind it and summarize the API structure.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
urlYesDocs page URL or direct OpenAPI JSON/YAML URL
authNoAuthentication for protected docs or OpenAPI documents
Behavior2/5

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 does not mention whether the tool fetches the document, how detection works, what happens with invalid URLs, or any side effects. The description adds little beyond the purpose.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is front-loaded with the core purpose. It is concise and contains no unnecessary words or information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 2 parameters and no output schema, the description is adequate but minimal. It does not describe return values, error behavior, or edge cases, but it conveys the essential function. It is complete enough for a simple tool but could be improved.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with clear descriptions for 'url' and 'auth' parameters. The tool description does not add additional semantic context beyond what the schema already provides, so a baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: detect an OpenAPI/Swagger document from a URL and summarize the API structure. It uses a specific verb (detect) and resource (OpenAPI document), and distinguishes from siblings like call_endpoint or list_endpoints.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives, no when-not-to-use conditions, and no mention of prerequisites or limitations. It only describes what the tool does.

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