MCP Proxy is a middleware service that enables multiple AI applications (like Claude Desktop, Cursor, and Windsurf) to communicate with different Model Context Protocol (MCP) endpoints through a unified interface. It acts as a proxy layer that:
- Accepts connections from various AI applications through STDIO or Server-Sent Events (SSE) transport protocols
- Routes these requests to appropriate MCP endpoints (MCP 1, MCP 2, etc.)
- Manages and standardizes the communication between AI applications and MCP services
This proxy service simplifies the integration of AI applications with MCP services by providing a centralized connection point and handling the complexity of protocol management and request routing. and request routing.
