sparfenyuk/mcp-proxy is a Python proxy that moves between the transports of MCP (Model Context Protocol) servers. It connects clients attached through standard input/output (stdio) to SSE or Streamable HTTP servers, and connects SSE to a local stdio server so that clients such as Claude Desktop can talk to remote servers. The repository's latest release is v0.13.0 and its license is MIT. However, the items changed in v0.13.0 are not given as release notes in this material. The source is the sparfenyuk/mcp-proxy repository on GitHub.
The tool acts as a bridge when the way clients attach differs from the way servers expose. The README describes both directions: connecting stdio to SSE or Streamable HTTP, and running SSE against a local stdio server. It can configure multiple named servers, and provides authentication options, CORS settings, and a /status endpoint that reports overall status. The repository was created in December 2024 and shows 2797 GitHub stars.
However, there is no evidence backing the stability of actual communication. The Momentum score in the research record is a low 1.0 out of 10, and no Freshness, Technology, or Quality scores are recorded. There are also no measurements showing transfer speed or the number of concurrent connections. The feature scope is clear, but how robust this bridge is in remote MCP server communication is hard to judge from this material alone.
