Agentbus

AgentBus The open-source event bus for AI agents. Webhooks in. Agent actions out.

---

Why

AI agents need events to act on. But connecting webhooks to agents means writing custom HTTP servers, parsing payloads, handling retries, and managing queues — for every single integration.

AgentBus is a lightweight, self-hosted event bus that handles all of that. Receive webhooks. Route to agents. Dispatch actions. Works with any AI framework: CrewAI, LangGraph, OpenAI Agents SDK, or plain HTTP.

Quick Start

npm install agentbus

import { AgentBus } from 'agentbus';

const bus = new AgentBus({
  handlers: [
    {
      name: 'issue-triage',
      pattern: 'github:issues.*',
      handle: async (ctx) => {
        ctx.logger.info(`New issue: ${ctx.event.payload.title}`);
        // Call your AI agent here
        return { success: true };
      },
    },
  ],
});

// Receive an event
await bus.emit({
  source: 'github',
  type: 'issues.opened',
  payload: { title: 'Bug: login fails', labels: ['bug'] },
});
