Openapi Fetch Mcp
What is Openapi Fetch Mcp
openapi-fetch-mcp is a CLI tool that converts OpenAPI endpoints into Model Context Protocol (MCP) tools, enabling seamless API integration with MCP-compatible clients.
Use cases
Use cases for openapi-fetch-mcp include integrating third-party APIs into applications, creating MCP tools for existing OpenAPI specifications, and facilitating API requests in a structured manner.
How to use
To use openapi-fetch-mcp, you can run it via the command line using ‘npx openapi-fetch-mcp’. You need to set environment variables for API_URL, CUSTOM_HEADERS, and either OPENAPI_URL or OPENAPI_FILE_PATH depending on whether you are using a remote or local OpenAPI specification.
Key features
Key features of openapi-fetch-mcp include fetching OpenAPI YAML from a URL or local file, registering each GET endpoint as an MCP tool, and supporting custom headers and environment variable configuration.
Where to use
openapi-fetch-mcp can be used in any environment where API integration is required, particularly in applications that need to communicate with MCP-compatible clients.

Features
- Fetches OpenAPI YAML from a URL or local file (Currently, only YAML format is supported)
- Registers each GET endpoint as an MCP tool (This library only supports GET requests for safety reasons)
- Supports custom headers and environment variable configuration

Environment Variables
OPENAPI_URL: URL to the OpenAPI YAML file (optional if usingOPENAPI_FILE_PATH)OPENAPI_FILE_PATH: Path to the local OpenAPI YAML file (optional if usingOPENAPI_URL)API_URL: Base URL for the API serverCUSTOM_HEADERS: (optional) JSON string for custom headers, e.g. ‘{“Authorization”:“Bearer …”}’
