Environment Setup

For full Expo CLI functionality, configure these environment variables:

Required for Android Development

# Android SDK location
export ANDROID_HOME=$HOME/Android/Sdk
export ANDROID_SDK_ROOT=$HOME/Android/Sdk

# Add Android tools to PATH
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/platform-tools

Java Version Management (Recommended)

Use jenv for managing Java versions:

# Install jenv (macOS)
brew install jenv

# Add to shell profile (~/.zshrc or ~/.bashrc)
export PATH="$HOME/.jenv/bin:$PATH"
eval "$(jenv init -)"

# Add Java versions
jenv add /Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Home

# Set global version (Java 17+ recommended for React Native)
jenv global 17

# Verify
java -version  # Should show 17.x.x or higher

Minimum Java Version: Java 17 (LTS) Recommended: Java 17 or 21 (LTS versions)

Why Java 17? Required for Android Gradle Plugin 8.0+ and modern React Native projects. Older versions may cause build failures.

🆕 Expert Remediation Examples

Before vs. After: Automatic Code Fixing

❌ Before (Problematic Code):

const MyComponent = () => {
  const apiKey = "sk-1234567890abcdef"; // Hardcoded secret
  const [data, setData] = useState([]);
  
  useEffect(() => {
    console.log("API Key:", apiKey); // Sensitive logging
    fetch('http://api.example.com/data') // HTTP instead of HTTPS
      .then(response => response.json())
      .then(data => setData(data));
      
    const interval = setInterval(() => { // Memory leak
      console.log('Polling...');
    }, 1000);
  }, []);

  return (
    <ScrollView>
      {data.map(item => ( // Performance issue
        <Text key={item.id} style={{color: 'red'}}>{item.name}</Text>
      ))}
    </ScrollView>
  );
};

✅ After (Expert Remediation):

interface Props {
  children?: React.ReactNode;
  onPress?: () => void;
}

const MyComponent: React.FC<Props> = () => {
  // TODO: Add API_KEY to your environment variables
  const apiKey = process.env.API_KEY || Config.API_KEY;
  const [data, setData] = useState([]);
  
  useEffect(() => {
    // Removed sensitive logging for security
    // console.log('[REDACTED - contains sensitive data]');
    
    // Upgraded to HTTPS for security
    fetch('https://api.example.com/data')
      .then(response => response.json())
      .then(data => setData(data));
      
    const interval = setInterval(() => {
      console.log('Polling...');
    }, 1000);
    
    // Cleanup intervals to prevent memory leaks
    return () => {
      clearInterval(interval);
    };
  }, []);

  return (
    <FlatList
      data={data}
      keyExtractor={(item, index) => item.id?.toString() || index.toString()}
      renderItem={({ item }) => (
        <Text style={styles.itemText}>{item.name}</Text>
      )}
    />
  );
};

const styles = StyleSheet.create({
  itemText: {
    color: 'red'
  }
});

export default React.memo(MyComponent);

🎯 What Got Fixed Automatically:

• ✅ Security: Hardcoded API key → Environment variable
• ✅ Security: Sensitive logging → Sanitized
• ✅ Security: HTTP → HTTPS upgrade
• ✅ Performance: ScrollView + map → FlatList with keyExtractor
• ✅ Memory: Added interval cleanup to prevent leaks
• ✅ Best Practices: Inline styles → StyleSheet.create
• ✅ Type Safety: Added TypeScript interface
• ✅ Performance: Wrapped with React.memo

⚠️ Known Limitations

Current Version (v0.1.0)

While the MCP server provides comprehensive React Native development capabilities, there are some known limitations based on real-world usage:

Process Management

• Manual process cleanup required: Port 8081 conflicts must be manually resolved using lsof -ti:8081 | xargs kill -9
• No session visibility: Cannot easily list or monitor active Expo/Metro processes
• Zombie sessions: No automatic cleanup of orphaned processes

Workarounds:

• Manually kill processes before starting new sessions
• Use ps aux | grep -E "expo|metro" to find running processes
• Tools in development: expo_sessions_list, expo_kill_process, expo_cleanup

Dependency Management

• Manual expo-doctor required: Users must run npx expo-doctor and npx expo install --check manually
• Multiple fix iterations: Dependency conflicts (27+ packages) require multiple rounds of manual fixes
• Version downgrades: Some packages (e.g., react-native-worklets 0.6.1 → 0.5.1) need manual attention

Workarounds:

• Run npx expo install --check before major builds
• Use expo install instead of yarn add for Expo packages
• Tools in development: expo_doctor, expo_install_check

Environment Validation

• Late build failures: Environment issues (Java version, ANDROID_HOME) not detected until builds fail
• Java 24 incompatibility: No pre-flight check for Java version compatibility with Gradle
• No proactive warnings: Issues discovered 10+ minutes into builds

Workarounds:

• Manually verify Java version: java -version (should be 17-21, not 24+)
• Use jenv to manage Java versions: jenv shell 17
• Check ANDROID_HOME before builds: echo $ANDROID_HOME
• Tools in development: expo_validate_environment

Polyfill Detection

• Manual polyfill setup: Users must manually add Buffer and EventTarget polyfills for Hermes
• Runtime errors only: Polyfill needs discovered only when app crashes
• 20+ lines of manual code: EventTarget implementation requires manual coding

Workarounds:

• Add polyfills to app/_layout.tsx before other imports
• Test on physical devices early to catch Hermes issues
• Tools in development: expo_detect_polyfills, expo_setup_polyfills

Tool Reliability

• 60% failure rate: In some sessions, ~60% of tool calls fail (vs. target >95%)
• Tool naming confusion: Incorrect prefix attempts (mcp__react-native-guide__* vs mcp__mcp-react-native-expo__*)
• Connection failures: MCP server reconnections fail without diagnostics
• Undefined returns: Some tools return undefined instead of proper error messages

Workarounds:

• Check tool names with expo_help() (when available)
• Restart Claude Desktop if tools become unavailable
• Use /mcp command to check server status
• Improvements in progress for v0.2.0

Log Management

• Token overflow: Build logs (34K+ tokens) exceed 25K limit
• Verbose Gradle output: 300+ lines of low-value logs make it hard to find errors
• No filtering: Cannot view errors-only or progress-only modes

Workarounds:

• Use tail parameter to limit log output
• Manually scan logs for "ERROR" or "WARN" keywords
• Tools in development: Smart log filtering with --errors-only, --progress modes

Impact Summary

Based on real-world usage analysis:

• ~41 minutes of manual work per typical workflow
• 16+ failed tool calls in a single session
• 90%+ of issues preventable with planned improvements

Improvement Timeline

See for detailed improvement plans.

All improvements consolidated into v0.1.0 release:

• ✅ Process management tools (sessions list, kill, cleanup)
• ✅ Standardized response format across all tools
• ✅ Tool reliability fixes (zero "no such tool" errors)
• ✅ Dependency management (expo-doctor, auto-fix versions)
• ✅ Environment validation (pre-build checks)
• ✅ Polyfill automation (detection and setup)
• ✅ Smart logging (errors-only, progress tracking)
• ✅ Build diagnostics (timeout detection, Gradle analysis)
• ✅ Interactive help system (expo_help, error codes)
• ✅ Comprehensive documentation

Target: >95% tool success rate, <5 minutes manual intervention per workflow

🔧 Troubleshooting

Quick Fixes for Common Issues

Port 8081 Already in Use

# Find and kill the process
lsof -ti:8081 | xargs kill -9

# Or kill all Metro/Expo processes
pkill -f "metro|expo"

Java Version Error (Gradle Builds)

# Check current version
java -version

# If showing Java 24, switch to 17 or 21
jenv shell 17

# Verify
java -version  # Should show 17.x.x

Buffer/EventTarget Polyfill Errors

Add to app/_layout.tsx (before imports):

// Minimal Buffer polyfill
if (typeof global.Buffer === 'undefined') {
  global.Buffer = {
    from: (data: any) => String(data),
    isBuffer: () => false,
  } as any;
}

// EventTarget polyfill
if (typeof global.EventTarget === 'undefined') {
  global.EventTarget = class EventTarget {
    private listeners = new Map();
    addEventListener(type: string, listener: Function) {
      if (!this.listeners.has(type)) {
        this.listeners.set(type, new Set());
      }
      this.listeners.get(type)?.add(listener);
    }
    removeEventListener(type: string, listener: Function) {
      this.listeners.get(type)?.delete(listener);
    }
    dispatchEvent(event: any) {
      this.listeners.get(event.type)?.forEach(l => l(event));
      return true;
    }
  } as any;
}

Dependency Version Conflicts

# Check for issues
npx expo-doctor

# Auto-fix all
npx expo install --check --fix

# Install missing peer dependencies
yarn add @expo/metro-runtime react-native-worklets

MCP Tools Not Available
