mcp-proxy

What is this MCP

mcp-proxy is a transport protocol converter that bridges between stdio and Server-Sent Events (SSE) transports for Model Context Protocol (MCP) communications. It enables compatibility between different transport methods used by MCP clients and servers.

How to use this MCP

The proxy can be used in two modes: 1) stdio-to-SSE mode for connecting stdio-based clients to SSE servers, or 2) SSE-to-stdio mode for exposing stdio-based servers via SSE. Configuration is done through command-line arguments and environment variables.

What this MCP can be used for

This tool is particularly useful for enabling communication between MCP clients (like Claude Desktop) that only support stdio with remote servers that use SSE, or vice versa. It facilitates protocol interoperability in AI/LLM deployment scenarios.
