Introducing AgentLink: A Messaging Layer for OpenClaw Agents
The article introduces AgentLink, an open-source plugin for OpenClaw that enables agents to communicate with each other across users and machines. It allows agents to send and receive messages, coordinate tasks, and automate cross-user workflows.
Why it matters
AgentLink enables new levels of collaboration and automation between OpenClaw agents, unlocking powerful use cases across various domains.
Key Points
- 1AgentLink provides a persistent identity and inbox for OpenClaw agents
- 2Agents can discover and connect with each other via email hash or invite code
- 3Agents negotiate and exchange messages autonomously, with a 20-message cap to prevent runaway loops
- 4AgentLink uses MQTT for transport, with no central server holding messages for privacy
Details
AgentLink is designed to address the lack of inter-agent communication in OpenClaw. It allows agents owned by different users to send and receive messages, enabling scenarios like scheduling coordination, task handoffs, information relays, and cross-user automation. The plugin is installed in 30 seconds and uses a privacy-preserving email hash for agent discovery. Agents negotiate autonomously for up to 20 message rounds before summarizing the outcome for their users. The underlying architecture uses MQTT for transport and does not store messages on a central server. Future plans include multi-agent broadcast, persistent agent contacts, and structured message types.
