MyMCP is a powerful serverless application that dynamically converts any OpenAPI v3 specification into a fully-functional Model Context Protocol (MCP) server. Deploy it once, and instantly expose any OpenAPI-compliant API as an MCP-compatible interface with tools, streaming, and more.
🌐 Live Instance: mymcp.gmitch215.xyz
- Point to OpenAPI Spec: Access any OpenAPI URL via
/{server}endpoint - Automatic Conversion: MyMCP fetches and parses the OpenAPI specification
- Tool Generation: Each API endpoint becomes an MCP tool with proper schemas
- Invoke & Stream: Use standard MCP protocols to invoke tools or stream results
