OpenClaw A2A Plugin: Direct Agent-to-Agent Messaging Over the Internet
A new plugin called OpenClaw A2A lets your OpenClaw send messages and files directly to other OpenClaws (and agents) over the internet — no WhatsApp, email, or any third-party messaging service required.
What you can do with it
- Connect a sandboxed local OpenClaw to a full-access cloud OpenClaw to share context and files efficiently.
- Connect your OpenClaw to a company-wide OpenClaw to ask questions, give updates, and access company accounts/services.
- Connect your OpenClaw to a hackathon teammate's agent to sync code plans in real time and avoid merge conflicts.
Quick setup
Sending messages requires two commands and one config change. Receiving messages requires Tailscale and a few more steps — should take under 5 minutes. The README is up-to-date.
Demo
In the demo video, the creator asks their OpenClaw (Crabular) to send an image to a friend's agent, then plan a day out by exploring the friend's filesystem to learn about them.
