# A2A Connect OpenClaw to other agents using the Agent2Agent protocol. The plugin publishes an Agent Card, receives authenticated tasks, and sends messages to configured peers using A2A 1.0 JSON-RPC. ## Get started Enable `channels.a2a`, set your public `advertisedUrl`, and configure a separate bearer token for each trusted peer under `channels.a2a.peers`. Add a peer's URL and outbound token when OpenClaw should initiate messages to it. Agent Card discovery is public. Limit `channels.a2a.exposeAgents` if only selected agents should be advertised. Peers can submit text tasks, not operator slash commands. Streaming, file transfer, and task cancellation are not supported. See the [A2A guide](https://docs.openclaw.ai/channels/a2a) for configuration, authentication, and task polling.
