OpenAPI to Model Context Protocol (MCP) proxy server - dynamically translates OpenAPI specs into MCP tools
Connect Openapi to Claude, Cursor or any other MCP client and it stops being a tab you switch to. OpenAPI to Model Context Protocol (MCP) proxy server - dynamically translates OpenAPI specs into MCP tools. The openapi mcp server is what makes that connection.
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.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Repository — ** https://github.com/gujord/OpenAPI-MCPRapidAPI — MCP_AUTH_HEADERS='{"X-RapidAPI-Key": "your-key"}'Installation — The Installation tool exposed by this serverResources — The Resources tool exposed by this serverPrompts — The Prompts tool exposed by this serverBenefits — The Benefits tool exposed by this serverMonitoring — The Monitoring tool exposed by this serveropenapi-mcp-proxy on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Configuration is passed through the environment: SERVER_NAME, OPENAPI_URL, MCP_AUTH_HEADERS, API_USERNAME, API_PASSWORD, OAUTH_CLIENT_ID, OAUTH_CLIENT_SECRET, OAUTH_TOKEN_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Openapi's toolset — Repository, RapidAPI, Installation and 4 more — is a fair guide to whether it matches your workflow.
