## Getting started

If you see a red `!` badge on the extension icon, the relay server is not reachable. Start OpenClaw’s browser relay on this machine (Gateway or node host), then click the toolbar button again.

Full guide (install, remote Gateway, security): docs.openclaw.ai/tools/chrome-extension

## Relay port

Port
Default: `18792`. Extension connects to: `http://127.0.0.1:<port>/`. Only change this if your OpenClaw profile uses a different `cdpUrl` port.
