## 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 connection

Port
Gateway token
Default port: `18792`. Extension connects to: `http://127.0.0.1:<port>/`. Gateway token must match `gateway.auth.token` (or `OPENCLAW_GATEWAY_TOKEN`).
