Android MCP Server

SocketBadge

MCP server for controlling Android emulators and devices via ADB. Gives AI assistants the ability to see, interact with, and debug Android apps — taking screenshots, tapping elements, reading logs, and documenting bugs.

Features

• 25 tools for complete Android device control
• Screenshot capture with intelligent compression (Sharp-based, max 1280px)
• UI tree inspection — read element hierarchy with bounds, text, resource IDs, and state
• Touch automation — tap, swipe, scroll, type text, press hardware keys
• Element targeting — find and tap elements by resource-id, text, or content-desc
• App lifecycle — install APKs, launch apps, inspect current activity
• Logcat integration — filter by package, log level, or timestamp
• Device management — list devices, start emulators, get device info
• Compound actions — tap_and_wait combines tap + settle + UI tree in one round trip
• Persistent ADB shell — reuses a single shell session for faster command execution
• Device info caching — queries device properties once per session
• Multi-device support — target specific devices by ID
• Zero app modifications — works with any Android app via ADB, no SDK integration needed

Prerequisites

• Node.js 18+
• Android SDK with platform-tools (ADB) and emulator
• A running Android emulator or connected device

Finding your ANDROID_HOME

The server auto-discovers the SDK at ~/Library/Android/sdk (macOS) or via ANDROID_HOME. If your SDK is elsewhere, set ANDROID_HOME in the MCP config (see below).

To check:

# macOS
ls ~/Library/Android/sdk/platform-tools/adb

# Or find it via Android Studio: Settings > Languages & Frameworks > Android SDK

Setup

claude mcp add --scope user android -- npx -y android-mcp-server

claude mcp add --scope user --env ANDROID_HOME=/path/to/sdk android -- npx -y android-mcp-server

Example Workflows

Bug documentation

"Clear the logs, open the settings screen, tap the save button, then show me the logs and a screenshot"

Claude will: clear_logs → launch_app → tap_element → get_logs(package_name="com.example.app", level="E") → screenshot(save_path="./bugs/settings-crash.png")

UI testing

"Navigate through the login flow and verify each screen matches the designs"

Claude will use screenshot + get_ui_tree to see and understand each screen, tap_element/type_text to interact, and its vision capabilities to compare against mockups or descriptions.

Smoke testing

"Install the APK, launch the app, and tap through the main screens to check nothing crashes"

Claude will: install_apk → launch_app → navigate with tap_element → get_logs(level="E") to check for errors after each screen.

Element interaction

"Open Settings, search for 'display', tap the first result, then go back"

Claude will: launch_app(package_name="com.android.settings") → tap_and_wait(by="text", value="Search settings") → type_text("display") → tap_and_wait(by="text", value="Display") → press_key(key="back")

How It Works

The server communicates over stdio using the Model Context Protocol. All device interaction goes through ADB — no modifications to your app are required. Screenshots are captured in memory, compressed, and returned as base64 images that the AI can see and analyze visually.
