Wiring Ag2 - Copilotkit

AG2 — wired via the bare HttpAgent from @ag-ui/client. No dedicated @ag-ui/ag2 package exists; AG2 is a standard HTTP AG-UI framework.

Install

bash

pnpm add @ag-ui/client

Minimal wire-up

typescript

import {
  CopilotRuntime,
  createCopilotRuntimeHandler,
} from "@copilotkit/runtime/v2";
import { HttpAgent } from "@ag-ui/client";

const runtime = new CopilotRuntime({
  agents: {
    default: new HttpAgent({
      url: process.env.AG2_URL ?? "http://localhost:8000/",
    }),
  },
});

const handler = createCopilotRuntimeHandler({
  runtime,
  basePath: "/api/copilotkit",
});

export default { fetch: handler };

Gotcha — no dedicated package

Unlike Mastra / LangGraph / CrewAI / LlamaIndex / Agno, AG2 has no @ag-ui/ag2 package. Always use the generic HttpAgent. If an older doc references a dedicated AG2 package, treat it as stale.
