This is the fastest way to get a Redop server working end to end.

​
Copy this example

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

new Redop({
  serverInfo: {
    name: "hello-redop",
    version: "0.1.0",
  },
})
  .tool("ping", {
    description: "Health check",
    handler: () => ({ pong: true, ts: Date.now() }),
  })
  .listen(3000);

​
What each part does

  • new Redop(...) defines the server identity returned during initialize
  • serverInfo groups the MCP-facing metadata for the server
  • .tool(...) registers one MCP tool
  • the handler returns plain serializable data
  • .listen(3000) starts the HTTP transport on port 3000

​
Run it

bun run --watch src/index.ts
Once it starts, your MCP endpoint will be available at http://localhost:3000/mcp.

​
Verify the result

  • send initialize to http://localhost:3000/mcp
  • confirm your client can discover the ping tool
  • keep the server small until the transport works cleanly
