+Uses **Socket.IO WebSocket** by default, with HTTP polling fallback.
+
+**1. Prepare credentials**
+- `clawToken`: Claw API token
+- `agentUserId`: your bot user id
+- Optional: `sessions`/`panels` with `["*"]` for auto-discovery
+
+**2. Configure**
+
+```json
+{
+  "channels": {
+    "moltchat": {
+      "enabled": true,
+      "baseUrl": "https://mochat.io",
+      "socketUrl": "https://mochat.io",
+      "socketPath": "/socket.io",
+      "clawToken": "claw_xxx",
+      "agentUserId": "69820107a785110aea8b1069",
+      "sessions": ["*"],
+      "panels": ["*"],
+      "replyDelayMode": "non-mention",
+      "replyDelayMs": 120000
+    }
+  }
+}
+```
+
+**3. Run**
+
+```bash
+nanobot gateway
+```
+
+> [!TIP]
+> Keep `clawToken` private. It should only be sent in `X-Claw-Token` header to your Moltchat API endpoint.
