| description | ERNE — Install and configure agent-device MCP server for simulator/emulator control |
You are executing the /erne-setup-device command. This is script-driven — it sets up the agent-device MCP server.
Installs and configures the agent-device MCP server so commands like /erne-debug, /erne-perf, /erne-component, and /erne-deploy gain visual device interaction capabilities.
# iOS: Check for Xcode and simulator
xcodebuild -version
xcrun simctl list devices
# Android: Check for Android Studio and emulator
adb version
emulator -list-avds
Check if already configured in .claude/settings.json:
{
"mcpServers": {
"agent-device": {
"command": "npx",
"args": ["-y", "agent-device"]
}
}
}
If not present, add the configuration.
# Boot a simulator (iOS)
xcrun simctl boot "iPhone 16 Pro"
# Or start an emulator (Android)
emulator -avd Pixel_8_API_35 &
Test that agent-device can:
After setup, these commands gain enhanced capabilities:
| Command | Enhancement |
|---|---|
/erne-debug | Screenshot reproduction steps, tap through UI |
/erne-perf | Measure real FPS, capture actual jank frames |
/erne-component | Render on device, visual verification screenshot |
/erne-deploy | Launch preview build, verify UI before submit |
/erne-build-fix | Build, install, and launch to verify fix |
## agent-device Setup Complete

Apple HIG design intelligence — build, review, animate, and analyze with Apple Human Interface Guidelines for React Native/Expo
Video-based visual debugging — extract key frames from screen recordings and analyze UI bugs over time. Detects animation glitches, race conditions, gesture issues, scroll jank, keyboard overlap, and navigation transitions that screenshots cannot capture.
