About Open MCP

Open MCP is a tool that converts any web API into a fully functional MCP server by parsing its OpenAPI/Swagger specification. Point it at an API spec, and it auto-generates all the MCP tools, parameter validation, and documentation. This enables AI agents to use any REST API without custom server code.
