Wiring Crewai Crews

CrewAI Crews — multi-agent crews wired via @ag-ui/crewai.

Install

pnpm add @ag-ui/crewai

Minimal wire-up

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

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

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

export default { fetch: handler };

Crews vs Flows

CrewAI ships two products:

• Crews — multi-agent orchestration. Use CrewAIAgent from @ag-ui/crewai.
• Flows — event-driven pipelines. Use the generic HttpAgent from @ag-ui/client (there's no framework-specific wrapper). See crewai-flows.md.

Gotcha — trailing slash

The url for CrewAIAgent traditionally ends with a trailing slash (http://localhost:8000/). Follow whatever your CrewAI server exposes — don't strip it.

Source: @ag-ui/crewai package types (CrewAIAgent constructor); docs/content/docs/reference/v1/sdk/python/CrewAIAgent.mdx for v1 Python-side reference. The v2 integrations docs currently ship only a Flows quickstart at docs/content/docs/integrations/crewai-flows/quickstart.mdx — there is no dedicated Crews quickstart yet.
