npm run dev        # Development mode with watch
npm test          # Run tests (if available)

Adding New Tools

To add the 4 pending tools to the TypeScript server:

1. Add tool definitions to the tools array in src/index.ts
2. Add corresponding case handlers in the switch statement
3. Map to existing Python client methods
4. Test with the comprehensive test suite

Architecture

MCP Client → TypeScript Server → Python Client → AlphaGenome API
    ↓              ↓                    ↓              ↓
Natural Lang → JSON Schema → Python SDK → REST API

🚨 Error Handling

The server provides comprehensive error handling for:

• ✅ Invalid DNA sequences - Character validation and length limits
• ✅ Malformed genomic coordinates - Position and chromosome validation
• ✅ API rate limits and errors - Proper error propagation
• ✅ Network connectivity issues - Timeout and retry handling
• ✅ Invalid parameter combinations - Input validation with Zod schemas
• ✅ JSON serialization limits - Graceful handling of large sequences

🔍 Troubleshooting

Common Issues

1. API Key Problems

# Verify API key is set
echo $ALPHAGENOME_API_KEY

# Test API connectivity
python3.11 -c "import alphagenome; print('API package ready')"

2. Python Version Issues

# Check Python version (requires 3.11+)
python3.11 --version

# Install AlphaGenome package
pip install alphagenome

3. Node.js Version

# Check Node.js version (requires 18+)
node --version

# Rebuild if needed
npm run build

4. MCP Configuration

• Ensure correct path to build/index.js
• Verify API key is properly set in environment
• Check MCP server logs for connection issues

📈 Performance Optimization

Best Practices

• Batch Processing: Use batch tools for multiple analyses
• Sequence Length: Use supported lengths (2KB, 16KB, etc.) for optimal performance
• Parallel Workers: Adjust max_workers based on your rate limits
• Error Handling: Implement retry logic for network issues

Rate Limiting

• The AlphaGenome API has usage limits
• Batch operations are more efficient than individual calls
• Monitor your API usage through Google DeepMind's dashboard
