About openapi-mcp-generator
abutbul/openapi-mcp-generator
A Python tool that automatically converts OpenAPI(Swagger, ETAPI) compatible specifications into fully functional Model Context Protocol (MCP) servers. Generates Docker-ready implementations with support for SSE/IO communication protocols, authentication, and comprehensive error handling. https://pypi.org/project/openapi-mcp-generator/
Converts OpenAPI specs into async-capable MCP servers with modular Python package architecture, supporting both SSE and stdio transports with pluggable authentication schemes. The generator produces Docker multi-stage builds alongside a CLI tool and programmatic API for integration into Python workflows. Built on OpenAPI parsing and Jinja2 templating, it handles rate limiting, comprehensive logging, and generates self-contained server implementations compatible with Claude and other MCP clients.
