Claw Use — Device Control for AI Agents

Give your AI agent eyes, hands, and a voice on real devices.

Claw Use is a protocol + skill for AI agents to control physical devices over HTTP. The cu CLI provides a unified interface — the same commands work across any device that implements the Claw Use API.

Supported Devices

Prerequisites

• cu CLI installed (ships with claw-use-android, or install standalone)
• At least one device running a Claw Use implementation
• Device and agent on the same network (or connected via Tailscale)

Setup

# Add a device with a friendly name
cu add redmi 192.168.0.105 <token>
cu add pixel 100.80.1.10 <token>

# List devices
cu devices
# ▸ redmi  192.168.0.105  online v1.2.0
#   pixel  100.80.1.10    offline

# Switch default
cu use pixel

# Target a specific device
cu -d redmi screenshot

Core API (all platforms)

Every Claw Use implementation exposes the same HTTP endpoints:

Perception — read the device

cu screen              # UI tree (semantic: element text, bounds, state)
cu screen -c           # compact mode (interactive elements only)
cu screenshot          # visual capture (JPEG, configurable quality)
cu notifications       # system notifications
cu status              # device health dashboard

Action — control the device

cu tap <x> <y>         # tap coordinates
cu click <text>        # tap by visible text (semantic click)
cu type "text"         # type text (CJK supported)
cu swipe up|down|left|right
cu scroll up|down|left|right
cu back / cu home      # system navigation
cu launch <app>        # open an application
cu open <url>          # open URL
cu intent '<json>'     # platform-specific intent (Android)

Audio

cu tts "hello"         # speak through device speaker
cu say "你好"          # alias

Device State

cu wake                # wake screen
cu lock / cu unlock    # lock/unlock (PIN required for unlock)

Workflow Patterns

Navigate and interact

cu launch org.telegram.messenger
cu screen -c                        # see what's on screen
cu click "Search"
cu type "John"
cu click "John, last seen recently"
cu type "Hey!"
cu click "Send"

Visual + semantic dual-channel

cu screen -c                         # semantic: what elements exist
cu screenshot 50 720 /tmp/look.jpg   # visual: what it actually looks like

Multi-device orchestration

cu -d phone1 launch com.whatsapp
cu -d phone2 screenshot
cu -d tablet open "https://example.com"

For Agent Developers

Claw Use is designed as a protocol, not just an app. To add support for a new platform:

1. Implement the Claw Use HTTP API spec
2. Expose endpoints on a configurable port (default: 7333)
3. Support token auth via X-Bridge-Token header
4. Return JSON responses matching the documented schemas

The cu CLI and this skill work automatically with any compliant implementation.

Tips

• cu screen -c is the primary perception tool — compact mode filters noise
• cu click by text is more reliable than cu tap when text is visible
• cu screenshot when you need visual context the UI tree can't capture
• Auto-unlock is transparent: locked devices auto-unlock before any command
• Combine with Tailscale for remote access from anywhere
