Open Source · A2A Protocol · Go + Next.js

What if your AI agent could hire other AI agents?

MetaAgent is a composable AI platform where every orchestrator is itself an agent. Agents discover, delegate, and compose recursively using the A2A protocol.

The Problem

Agents are stuck on islands

Each framework is a walled garden. Your agents can't reach across.

The Insight

The Kubernetes pattern, for AI agents

K8s didn't invent containers. It made them composable. MetaAgent does the same for A2A agents.

How It Works

Recursive composition in action

A user says "Plan our product launch." Watch what happens at each level.

LEVEL 0 — MetaAgent-HQ LEVEL 1 — Marketing MetaAgent LEVEL 1 — Engineering MetaAgent LEVEL 2 — Leaf Agents LEVEL 2 — Leaf Agents MetaAgent-HQ "Plan product launch" Marketing MA decomposes... Engineering MA decomposes... Legal waits waits Copywriter Social Media Designer dep QA DevOps Docs dep Results flow up: Leaf → MetaAgent → HQ → User Each level only sees its own agents. Natural encapsulation via A2A. MetaAgent (orchestrator + A2A agent) Leaf Agent (single-skill worker) Task delegation Dependency (waits for)
The Key Idea

MetaAgent is itself an A2A agent

It's not just a platform that runs agents. It IS an agent. Anything that speaks A2A or sends a webhook can trigger it.

MetaAgent A2A endpoint + orchestrator POST /a2a · webhooks · chat UPSTREAM TRIGGERS ★ GitHub Webhook PR opened, issue created # Slack @metaagent deploy v2.3 🧠 Another MetaAgent A2A tasks/send 💬 User Chat Natural language request 🔗 Any Webhook Jira, Linear, CI/CD, ... DOWNSTREAM AGENTS 🤖 Engineering Agent code review, deploy 🤖 Marketing Agent content, campaigns 🤖 Analytics Agent reports, dashboards 🧠 Another MetaAgent recursive delegation webhook / A2A A2A tasks/send GitHub push → MetaAgent decomposes → agents execute → PR comment posted Zero human intervention. Fully automated. Infinitely composable.
