The OpenAPI-MCP proxy translates OpenAPI specs into MCP tools, enabling AI agents to access external APIs without custom wrappers!

Bridge the gap between AI agents and external APIs

The OpenAPI to Model Context Protocol (MCP) proxy server bridges the gap between AI agents and external APIs by dynamically translating OpenAPI specifications into standardized MCP tools, resources, and prompts. This simplifies integration by eliminating the need for custom API wrappers.

Built with FastMCP following official MCP patterns and best practices, the server provides:

• ✅ Official FastMCP Integration - Uses the latest FastMCP framework for optimal performance

• ✅ Proper MCP Transport - Supports stdio, SSE, and streamable HTTP transports

• ✅ Modular Architecture - Clean separation of concerns with dependency injection

• ✅ Production Ready - Robust error handling, comprehensive logging, and type safety
