OpenAPI

Exposes HTTP methods from an OpenAPI specification as tools for Model Context Protocol (MCP) servers.
About
OpenAPI allows you to create a Model Context Protocol (MCP) server that uses an OpenAPI spec to define its available tools. It fetches and parses the OpenAPI specification, registers each path-operation as a tool, and starts a FastMCP server. This enables clients to request these tools, triggering HTTP requests to the API and returning the responses, effectively bridging OpenAPI defined APIs with the Model Context Protocol.
Key Features
- Resolves references to external specs.
- Can use a global auth token for API requests.
- Supports OpenAPI 3.0 and 3.1 specifications.
- Offers configuration options for the FastMCP server (host, port, debug mode, log level).
- Works with JSON and YAML formats.
- 2 GitHub stars
Use Cases
- Quickly expose API functionality as tools for LLMs.
- Integrate existing APIs defined by OpenAPI specs into MCP workflows.
- Create custom tools for LLMs based on specific API endpoints.
