mcp-proxy
Proxy for switching between stdio and SSE transports in MCP. mcp-proxy is a Model Context Protocol (MCP) server maintained by sparfenyuk. It connects to MCP-compatible clients such as Claude Desktop, Cursor, Cline, and other agents that speak the protocol. It exposes 1 tool, including mcp-proxy, that an agent can call directly. It is categorized under Tool/Proxy and AI/LLM.
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.
