mcp-proxy is a Python tool that bridges between Streamable HTTP and stdio MCP transports. It lets a server exposed over one transport be reached by clients using the other.

Use it when your MCP client and server speak different transports and you need a conversion layer between HTTP/SSE and stdio.

Use it to

  • Expose a stdio MCP server over Streamable HTTP
  • Connect an HTTP-based MCP client to a local stdio server
  • Bridge legacy SSE-based MCP setups to Streamable HTTP
  • Deploy MCP servers in Docker behind an HTTP proxy

For Developers running MCP servers and clients with mismatched transports
