mcp-sse-proxy

Overview

The MCP SSE Proxy serves as a translation layer between MCP servers using STDIO transport and clients using SSE transport. It enables real-time data streaming over web connections by converting MCP communication to the Server-Sent Events protocol. The proxy supports configurable ping intervals, debug logging, and environment variable forwarding, making it suitable for production use with ClaudeAI desktop configuration.
