OpenAPI

概要

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.

ユースケース

• 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.
