SSE传输层与MCP服务器

import express from "express";
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { SSEServerTransport } from "@modelcontextprotocol/sdk/server/sse.js";

const server = new McpServer({
  name: "example-server",

});

// ... set up server resources, tools, and prompts ...

const app = express();

app.get("/sse", async (req, res) => {
  const transport = new SSEServerTransport("/messages", res);
  await server.connect(transport);
});

app.post("/messages", async (req, res) => {
  // Note: to support multiple simultaneous connections, these messages will
  // need to be routed to a specific matching transport. (This logic isn't
  // implemented here, for simplicity.)
  await transport.handlePostMessage(req, res);
});

app.listen(3001);
