Deploy on Node.js - Redop

.listen() defaults to Bun. When you need Node specifically, use @redopjs/redop/node.

Quick start

import { Redop } from "@redopjs/redop";
import { listenNode } from "@redopjs/redop/node";

const app = new Redop({
  serverInfo: { name: "node-mcp", version: "0.1.0" },
}).tool("ping", {
  handler: async () => ({ ok: true }),
});

listenNode(app, {
  port: Number(process.env.PORT ?? 3000),
  hostname: "0.0.0.0",
  health: true,
  onListen: ({ url }) => console.log(`Redop on ${url}`),
});

Other Node shapes

nodeListener(app) / toNodeHandler(app) — attach to an existing node:http server
nodeFetch(app) — portable (Request) => Response for undici-style hosts

Notes

Node is a long-lived runtime, so afterResponse uses microtasks (same model as Bun).
Sessioned MCP and SSE work the same as the Bun HTTP transport on a single process.
For Cloudflare or Vercel, use cloudflare(app) or vercel(app) instead of the Node listener.
