ADB Friend

ADB Friend

ADB Friend is a tiny cli tool, which helps you to manage your Android device via ADB. Its features were mostly designed for developers, but it can be useful for everyone.

Features

• Sync files from your computer to your phone
  • Designed for test data, skipping existing files on device
• Configure device for tests
  • Disable animations, Enable touches, ...
• Uninstall apps by pattern
• Packages command
  • Apply the immersive flag to all packages matching glob, force-stop, clear app data & cache
• Extra tools
  • adb-speed (Helps to identify sub-par cables)
• Model Context Protocol MCP Server

Install

The installation can be performed using Homebrew. First you'll require the custom tap:

brew tap mikepenz/tap

Next, install the AdbFriend CLI:

brew install mikepenz/tap/adbfriend

Alternatively, you can download prebuild binaries for release page.

Usage

ADB Friend is a command line tool, which can be used in a terminal.

# Get started with the `--help` command, to get information and an overview on the various features offered.
adbfriend --help

MCP Server

ADB Friend (Since version 1.4.0) also provides a Model Context Protocol (MCP) Server, that can be configured in popular AI Tools like Claude Desktop, GitHub Copilot, RayCast, ...

Configuration

The location and details of the configuration file will depend on the used tool. Below example for Claude Desktop.

{
  "mcpServers": {
    "adb-friend": {
      "command": "/opt/homebrew/bin/adbfriend",
      "args": [
        "mcp",
        "server"
      ],
      "env": {
        "ANDROID_HOME": "/Users/mikepenz/Development/android/sdk"
      }
    }
  }
}

Important

If ANDROID_HOME is not provided, the adb-server has to be manually started on your machine. Otherwise, a connection exception is thrown.

Debug Server

You can use the npx @modelcontextprotocol/inspector to debug the server once started.

# Install and run inspector in your terminal
npx @modelcontextprotocol/inspector

Then launch the website (with the url as provided in the terminal). Launch the mcp server using IntelliJ or the actual command.

# Default port is `3001`
adbfriend mcp server --sse true
