FastMCP

概要

This server acts as a Model Context Protocol (MCP) gateway, automatically converting OpenAPI-defined REST service endpoints into callable MCP tools. It operates by fetching the OpenAPI specification from a target service (e.g., Spring Boot's /v3/api-docs), mapping each operationId to a distinct MCP tool, and then constructing and invoking HTTP requests to the original service when a tool is called. This streamlines the integration of existing REST APIs into MCP-driven workflows, supporting configurable base URLs, context paths, and automatic injection of required HTTP headers like x-group and x-hospital.
