Android MCP

Full Android control from any AI agent — Claude, OpenCode, Windsurf, Cursor… 7 categorical MCP tools · 90fps live viewer · WiFi ADB · zero app to install

Quick demo

android_screen(action="screenshot")                          # PNG capture
android_screen(action="ocr")                                 # visible text
android_interact(action="tap", params={"x": 540, "y": 960}) # tap
android_interact(action="find", params={"text": "Send"})     # find + tap
android_system(action="battery")                             # battery info
android_screen(action="viewer")                              # 90fps interactive window on PC

Architecture

AI Agent (Claude / OpenCode / Windsurf / Cursor…)
        ↓  MCP Protocol (stdio)
    server.py          ← 7 categorical tools
        ↓
    device_manager.py  ← device selection, multi-device
        ↓
    backends/
        ├── adb_backend.py       ← PRIMARY  : uiautomator2 + direct ADB
        └── companion_backend.py ← FALLBACK : Flutter app WebSocket
        ↓
    N Android phones / emulators

ADB backend (primary) — works on any device with developer mode enabled. Nothing to install on the phone. Uses uiautomator2 + ADB commands.

Companion backend (fallback) — optional Flutter app when ADB is unavailable on the network.

Requirements

• Python 3.10+
• ADB in PATH (winget install Google.PlatformTools)
• Android: Developer mode + USB debugging (or WiFi debugging)

Installation

git clone https://github.com/Steph-ux/android-mcp
cd android-mcp
pip install -r requirements.txt

# Initialize uiautomator2 (once per device)
python -m uiautomator2 init

Live viewer 90fps (optional)

winget install Genymobile.scrcpy
python viewer.py

MCP Configuration

# Generate the correct JSON for your AI client
python mcp_config.py --client claude     # Claude Desktop
python mcp_config.py --client opencode  # OpenCode
python mcp_config.py --client windsurf  # Windsurf
python mcp_config.py --client cursor    # Cursor
python mcp_config.py --write            # write directly to config files

Claude Desktop example (claude_desktop_config.json):

{
  "mcpServers": {
    "android-mcp": {
      "command": "C:/Python312/python.exe",
      "args": ["D:/path/to/android-mcp/server.py"],
      "type": "stdio"
    }
  }
}

WiFi connection without USB (Android 11+)

# On the phone: Settings → Developer options → Wireless debugging → Pair device
adb pair 192.168.1.42:38765    # enter the code shown on the phone
adb connect 192.168.1.42:5555

The 7 MCP tools

Call convention: android_xxx(action="...", params={...}, device_id="serial") device_id is always optional (uses the currently selected device).

android_device — Device management

android_screen — Capture & Stream

android_interact — Touch, Keyboard, UI

android_app — Applications

android_files — Files

android_system — System & Network

android_automation — Batch & Macros

Live viewer — scrcpy 90fps

python viewer.py                  # auto-detect device, 90fps, interactive
python viewer.py --fps 60         # 60fps
python viewer.py --record         # record to .mp4
python viewer.py --record out.mp4 # named output file
python viewer.py --multi          # one viewer per connected device
python viewer.py --no-control     # read-only mode

Tests

# Unit tests (no device required)
pytest tests/test_server_unit.py -v      # 94 tests

# Integration tests (ADB device required)
pytest tests/test_integration.py -v
