A simple, secure MCP-to-OpenAPI proxy server
McPO is a Python proxy server that wraps any MCP server and re-exposes its tools as a standard OpenAPI-compatible HTTP endpoint, eliminating the raw stdio transport that MCP servers normally rely on. Running a single command such as `uvx mcpo --port 8000 --api-key "top-secret" -- uvx mcp-server-time` instantly produces a live REST API with auto-generated interactive documentation at `/docs`, requiring no hand-written schemas or glue code. It accepts a JSON config file that follows the Claude Desktop `mcpServers` format, allowing multiple servers to run simultaneously under separate routes like `/memory` and `/time`, each with its own dedicated OpenAPI schema. The proxy supports stdio, SSE, and Streamable HTTP transport types, optional API key authentication, OAuth 2.1 with dynamic client registration, reverse-proxy subpath routing via `--root-path`, and a `--hot-reload` flag for zero-downtime config changes. Developers building LLM agents, Open WebUI integrations, or any OpenAPI-aware toolchain benefit most, since they can consume MCP tools through familiar HTTP clients without protocol-specific handling.
