OpenClaw A2A Gateway

One agent can't do everything. Specialized agents need to talk to each other. A2A gateway makes that happen.

What breaks without openclaw multi-agent a2a

Monolithic bots doing too many jobs badly. No agent delegation layer. Multi-agent pipelines require custom IPC.

Multi-agent task delegation × A2A protocol standard gateway ÷ 90-minute setup ÷ no custom IPC required = specialized agents that outperform monolithic ones.

openclaw multi-agent a2a — what it actually does

01
Implements the A2A protocol for OpenClaw agent-to-agent communication.
02
Routes tasks from a coordinator agent to specialized downstream agents.
03
Assembles outputs from multiple agents into a unified response.
04
Supports dynamic agent discovery — agents register capabilities at startup.
05
Works across separate OpenClaw instances for distributed agent networks.

Security check — openclaw multi-agent a2a

Privacy score: 7/10 — accesses connected platform APIs only. Lock it: review OAuth scopes before install, confirm Linux, macOS; OpenClaw ≥1.3; compatible with Google A2A protocol spec compatibility.

Quick start — openclaw multi-agent a2a in 45–90 minutes

Setup time: 45–90 minutes

!
You need:
  • Multiple OpenClaw instances or agents
  • Node.js ≥18
  • basic understanding of A2A protocols

Install the package:

git clone https://github.com/win4r/openclaw-a2a-gateway
cd openclaw-a2a-gateway && npm install
npm start
1
Clone and install the gateway
2
Define your agent registry in a2a.config.json (agent IDs, endpoint URLs, capabilities)
3
Start the gateway
4
In each OpenClaw agent, install the a2a-client SDK
5
Implement a capability declaration in each agent's config
6
Test with a delegated task — agent A delegates a subtask to agent B via the gateway

Troubleshooting openclaw multi-agent a2a

1
1. Not declaring agent capabilities — the gateway uses capability declarations for routing
2
2. Creating circular delegation loops — agent A delegates to agent B which delegates back to agent A
3
3. Not setting message TTL — circular or orphaned tasks can loop indefinitely

Compatibility & status

FAQ — openclaw multi-agent a2a

Does this gateway implement the full Google A2A spec?

A subset — core task delegation and capability discovery flows are implemented.

Can agents be on different servers?

Yes. Each agent is registered with its HTTP endpoint URL.

How does this relate to openclaw-better-gateway?

Better-gateway handles webhook load balancing; A2A-gateway handles inter-agent task delegation.
