What it does

MCP Proxy is a bidirectional bridge that allows MCP clients (like Claude Desktop or Cursor) to connect to remote MCP servers via SSE or Streamable HTTP, or conversely, expose local stdio servers to the web.

Tools

As a proxy, it does not expose its own tools but instead forwards tools from the connected upstream MCP server to the client. It manages the transport layer, ensuring seamless communication between different MCP protocols.

Installation

Install via Cargo: cargo install rmcp-proxy

To use with Claude Desktop, add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "my-remote-server": {
      "command": "mcp-proxy",
      "args": ["http://example.com/mcp/instances_abc123"]
    }
  }
}

Supported hosts

Confirmed for Claude and Cursor.

Quick install

cargo install rmcp-proxy
