AI Agent Configuration
This MCP server works with AI agents that support the Model Context Protocol. Configure your preferred agent to enable real-time Android UI analysis:
Claude Code
# CLI Installation
claude mcp add android-ui-assist -- npx android-ui-assist-mcp
# Local Development
claude mcp add android-ui-assist -- node "D:\\projects\\android-ui-assist-mcp\\dist\\index.js"
Claude Desktop
Add to %APPDATA%\Claude\claude_desktop_config.json:
{
"mcpServers": {
"android-ui-assist": {
"command": "npx",
"args": ["android-ui-assist-mcp"],
"timeout": 10000
}
}
}
GitHub Copilot (VS Code)
Add to .vscode/settings.json:
{
"github.copilot.enable": {
"*": true
},
"mcp.servers": {
"android-ui-assist": {
"command": "npx",
"args": ["android-ui-assist-mcp"],
"timeout": 10000
}
}
}
Gemini CLI
# CLI Installation
gemini mcp add android-ui-assist npx android-ui-assist-mcp
# Configuration
# Create ~/.gemini/settings.json with:
{
"mcpServers": {
"android-ui-assist": {
"command": "npx",
"args": ["android-ui-assist-mcp"]
}
}
}
Installation
Package Manager Installation
npm install -g android-ui-assist-mcp
Source Installation
git clone https://github.com/yourusername/android-ui-assist-mcp
cd android-ui-assist-mcp
npm install && npm run build
Installation Verification
After installation, verify the package is available:
android-ui-assist-mcp --version
# For npm installation
npx android-ui-assist-mcp --version
Development Workflow
This MCP server transforms how you develop Android UIs by giving AI agents real-time visual access to your running application. Here's the typical workflow:
- Start Your Development Environment: Launch Expo, React Native Metro, Flutter, or Android Studio with your app running
- Connect the MCP Server: Configure your AI agent (Claude, Copilot, Gemini) to use this MCP server
- Iterative Development: Ask your AI agent to analyze the current UI, suggest improvements, or help implement changes
- Real-Time Feedback: The AI agent takes screenshots to see the results of code changes immediately
- Refine and Repeat: Continue the conversation with visual context for better UI development
Perfect for:
- Expo development with live preview and hot reload
- React Native development with Metro bundler
- Flutter development with hot reload
- Native Android development with instant run
- UI testing and visual regression analysis
- Collaborative design reviews with AI assistance
- Accessibility testing with visual context
- Cross-platform UI consistency checking
Prerequisites
| Component | Version | Installation |
|---|---|---|
| Node.js | 18.0+ | Download |
| npm | 8.0+ | Included with Node.js |
| ADB | Latest | Android SDK Platform Tools |
Android Device Setup
- Enable Developer Options: Settings > About Phone > Tap "Build Number" 7 times
- Enable USB Debugging: Settings > Developer Options > USB Debugging
- Verify connection:
adb devices
Development Environment Setup
Expo Development
- Start your Expo development server:
npx expo start
# or
npm start
- Open your app on a connected device or emulator
- Ensure your device appears in
adb devices - Your AI agent can now take screenshots during development
React Native Development
- Start Metro bundler:
npx react-native start
- Run on Android:
npx react-native run-android
- Enable hot reload for instant feedback with AI analysis
Flutter Development
- Start Flutter in debug mode:
flutter run
- Use hot reload (
r) and hot restart (R) while getting AI feedback - The AI agent can capture UI states after each change
Native Android Development
- Open project in Android Studio
- Run app with instant run enabled
- Connect device or start emulator
- Enable AI agent integration for real-time UI analysis
Docker Deployment
Docker Compose
cd docker
docker-compose up --build -d
Configure AI platform for Docker:
{
"mcpServers": {
"android-ui-assist": {
"command": "docker",
"args": ["exec", "android-ui-assist-mcp", "node", "/app/dist/index.js"],
"timeout": 15000
}
}
}

Usage Examples
Example: AI agent listing devices, capturing screenshots, and providing detailed UI analysis in real-time
Real-Time UI Development
With your development environment running (Expo, React Native, Flutter, etc.), interact with your AI agent:
Initial Analysis:
- "Take a screenshot of my current app UI and analyze the layout"
- "Show me the current state of my login screen and suggest improvements"
- "Capture the app and check for accessibility issues"
Iterative Development:
- "I just changed the button color, take another screenshot and compare"
- "Help me adjust the spacing - take a screenshot after each change"
- "Take a screenshot and tell me if the new navigation looks good"
Cross-Platform Testing:
- "Capture screenshots from both my phone and tablet emulator"
- "Show me how the UI looks on device emulator-5554 vs my physical device"
Development Debugging:
- "List all connected devices and their status"
- "Take a screenshot from the specific emulator running my debug build"
- "Capture the current error state and help me fix the UI issue"
Troubleshooting
ADB Issues
- ADB not found: Verify ADB is installed and in PATH
- No devices: Check USB connection and debugging authorization
- Device unauthorized: Disconnect/reconnect USB, check device authorization prompt
- Screenshot failed: Ensure device is unlocked and properly connected
Connection Issues
- Verify
adb devicesshows your device as "device" status - Restart ADB server:
adb kill-server && adb start-server - Check USB debugging permissions on device
