概要

What is API Docs MCP?

API Docs MCP is an MCP server that provides tools for interacting with API documentation. It supports GraphQL, OpenAPI/Swagger, and gRPC specifications, fetching schema definitions from local files or remote URLs, caching them, and exposing them through a set of tools.

How to use API Docs MCP?

Configure API sources via the API_SOURCES environment variable, then run the MCP server. The server automatically registers tools from a specified directory. Use the api_docs tool to list available API methods and api_search to retrieve detailed documentation for specific methods.

よくある質問

How do I configure API sources?

Set the `API_SOURCES` environment variable to specify the schema files or URLs. The format supports local file paths and remote URLs for GraphQL, OpenAPI, and gRPC.

What schema formats are supported?

GraphQL schemas can be loaded from `.graphql`, `.gql`, or JSON introspection results. OpenAPI/Swagger supports YAML and JSON. gRPC supports `.proto` files or reflection from remote URLs.

How does caching work?

The server caches schema data after fetching to reduce redundant requests. It automatically refreshes the cache periodically to keep documentation up-to-date.

Does the server require any runtime dependencies?

The server runs as an MCP server and is configured entirely through the `API_SOURCES` environment variable. No additional authentication or transport setup is required.
