Android device control through MCP and a deterministic CLI

opdroid

Android device control through MCP and a deterministic CLI.

opdroid exposes a connected Android device as a set of practical tools: capture a gridded screen, inspect UI hierarchy, tap cells, swipe, type text, press Android navigation keys, and launch apps. Bring your own MCP-capable agent.

Requirements

• Python 3.10+
• ADB installed and running
• Android device or emulator with USB debugging enabled

Installation

pip install opdroid

For local development:

uv sync
uv run opdroid --help

MCP Server

Run the MCP server over stdio:

opdroid mcp

Target a specific device:

opdroid mcp --serial emulator-5554

Print a ready-to-copy MCP config snippet:

opdroid mcp-config

Example config:

{
  "mcpServers": {
    "opdroid": {
      "command": "opdroid",
      "args": ["mcp"]
    }
  }
}

Agent Skill

Print the recommended skill text for another agent:

opdroid skill

The MCP server also exposes this through get_android_use_skill.

CLI

List devices:

opdroid devices

Capture the current screen with a grid and UI hierarchy:

opdroid screen --output artifacts/screen.png

Operate the device:

opdroid tap E10
opdroid tap-sequence B16 E16 H16
opdroid swipe E18 E6
opdroid input-text "hello world"
opdroid press back
opdroid launch-app com.android.settings

MCP Tools

• get_screen: returns a gridded screenshot and compact interactive element list.
• tap: tap a grid cell.
• tap_sequence: tap multiple grid cells.
• swipe: swipe between two grid cells.
• input_text: type text into the focused field.
• press_home, press_back, press_enter, press_recent_apps: Android key actions.
• launch_app: launch an app by package name.
• wait: wait for loading or animation.
• list_devices: list connected Android devices.
• get_android_use_skill: return the recommended agent skill text.

Configuration

By default opdroid connects to ADB at 127.0.0.1:5037.

Environment variables:

• OPDROID_ADB_HOST: ADB server host.
• OPDROID_ADB_PORT: ADB server port.
• OPDROID_CELL_SIZE: grid cell size in analysis screenshots.

Equivalent CLI options are available where device access is needed:

opdroid devices --adb-host 127.0.0.1 --adb-port 5037
opdroid mcp --adb-host 127.0.0.1 --adb-port 5037

Development Checks

uv run python -m compileall src tests
uv run opdroid --help
