About

The `mcp-proxy` is a tool that lets you switch between server transports. There are two supported modes:

1. stdio to SSE/StreamableHTTP
2. SSE to stdio

1. stdio to SSE/StreamableHTTP

Run a proxy server from stdio that connects to a remote SSE server.

This mode allows clients like Claude Desktop to communicate to a remote server over SSE even though it is not supported natively.
