### HTTP with SSE
For remote servers, start a web server with a Server-Sent Events (SSE) endpoint, and a separate endpoint for the client to send its messages to:
```typescript
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",
version: "1.0.0"
});
// ... 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);
```
