API Docs MCP

MCP server that provides tools for interacting with API documentation. Supports GraphQL, OpenAPI/Swagger, and gRPC specifications, fetching schema definitions from various sources (local files or remote URLs), caching them, and exposing them through a set of tools.

Features

Dynamic Tool Registration: Automatically discovers and registers tools from a specified directory.
API Documentation Retrieval: Provides tools to list available API methods (api_docs) and retrieve detailed documentation for specific methods (api_search).
Schema Caching: Caches API schema information to reduce redundant fetches and improve performance.
Multiple Source Support:
- GraphQL: Supports loading GraphQL schemas from graphql / gql files or json introspection results (local files or remote URLs).
- OpenAPI/Swagger: Supports loading OpenAPI/Swagger yaml / yml / json schemas from local files or remote URLs.
- gRPC: Supports loading gRPC schemas from proto files or via gRPC reflection from remote URLs.
Environment-based Configuration: Configures API sources via the API_SOURCES environment variable, allowing flexible deployment and management.
Automatic Cache Refresh: Periodically refreshes cached schema data to ensure up-to-date documentation.

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
