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
