Nodes
A node is a companion device (iOS/Android today) that connects to the Gateway over the Bridge and exposes a command surface (e.g.canvas.*, camera.*, system.*) via node.invoke. Bridge protocol details: Bridge protocol.
macOS can also run in node mode: the menubar app connects to the Gateway’s bridge and exposes its local canvas/camera commands as a node (so clawdbot nodes … works against this Mac).
Notes:
- Nodes are peripherals, not gateways. They don’t run the gateway daemon.
- Telegram/WhatsApp/etc. messages land on the gateway, not on nodes.
Pairing + status
Pairing is gateway-owned and approval-based. See Gateway pairing for the full flow. Quick CLI:nodes renamestores a display name override in the gateway pairing store.
Invoking commands
Low-level (raw RPC):Screenshots (canvas snapshots)
If the node is showing the Canvas (WebView),canvas.snapshot returns { format, base64 }.
CLI helper (writes to a temp file and prints MEDIA:<path>):
Canvas controls
canvas presentaccepts URLs or local file paths (--target), plus optional--x/--y/--width/--heightfor positioning.canvas evalaccepts inline JS (--js) or a positional arg.
A2UI (Canvas)
- Only A2UI v0.8 JSONL is supported (v0.9/createSurface is rejected).
Photos + videos (node camera)
Photos (jpg):
mp4):
- The node must be foregrounded for
canvas.*andcamera.*(background calls returnNODE_BACKGROUND_UNAVAILABLE). - Clip duration is clamped (currently
<= 60s) to avoid oversized base64 payloads. - Android will prompt for
CAMERA/RECORD_AUDIOpermissions when possible; denied permissions fail with*_PERMISSION_REQUIRED.
Screen recordings (nodes)
Nodes exposescreen.record (mp4). Example:
screen.recordrequires the node app to be foregrounded.- Android will show the system screen-capture prompt before recording.
- Screen recordings are clamped to
<= 60s. --no-audiodisables microphone capture (supported on iOS/Android; macOS uses system capture audio).- Use
--screen <index>to select a display when multiple screens are available.
Location (nodes)
Nodes exposelocation.get when Location is enabled in settings.
CLI helper:
- Location is off by default.
- “Always” requires system permission; background fetch is best-effort.
- The response includes lat/lon, accuracy (meters), and timestamp.
SMS (Android nodes)
Android nodes can exposesms.send when the user grants SMS permission and the device supports telephony.
Low-level invoke:
- The permission prompt must be accepted on the Android device before the capability is advertised.
- Wi-Fi-only devices without telephony will not advertise
sms.send.
System commands (mac node)
The macOS node exposessystem.run and system.notify.
Examples:
system.runreturns stdout/stderr/exit code in the payload.system.notifyrespects notification permission state on the macOS app.system.runsupports--cwd,--env KEY=VAL,--command-timeout, and--needs-screen-recording.system.notifysupports--priority <passive|active|timeSensitive>and--delivery <system|overlay|auto>.
Permissions map
Nodes may include apermissions map in node.list / node.describe, keyed by permission name (e.g. screenRecording, accessibility) with boolean values (true = granted).
Mac node mode
- The macOS menubar app connects to the Gateway bridge as a node (so
clawdbot nodes …works against this Mac). - In remote mode, the app opens an SSH tunnel for the bridge port and connects to
localhost.
