MCP Proxy
A TypeScript SSE proxy for MCP servers that use stdio
transport.
[!NOTE] CORS is enabled by default.
[!NOTE] For a Python implementation, see mcp-proxy.
[!NOTE] MCP Proxy is what FastMCP uses to enable SSE.
Installation
npm install mcp-proxy
Quickstart
Command-line
npx mcp-proxy --port 8080 --endpoint /sse tsx server.js
This starts an SSE server and stdio
server (tsx server.js
). The SSE server listens on port 8080 and endpoint /sse
, and forwards messages to the stdio
server.
Node.js SDK
The Node.js SDK provides several utilities that are used to create a proxy.
proxyServer
Sets up a proxy between a server and a client.
const transport = new StdioClientTransport();
const client = new Client();
const server = new Server(serverVersion, {
capabilities: {},
});
proxyServer({
server,
client,
capabilities: {},
});
In this example, the server will proxy all requests to the client and vice versa.
startSSEServer
Starts a proxy that listens on a port
and endpoint
, and sends messages to the attached server via SSEServerTransport
.
import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { startSSEServer } from "mcp-proxy";
const { close } = await startSSEServer({
port: 8080,
endpoint: "/sse",
createServer: async () => {
return new Server();
},
});
close();
tapTransport
Taps into a transport and logs events.
import { tapTransport } from "mcp-proxy";
const transport = tapTransport(new StdioClientTransport(), (event) => {
console.log(event);
});
