🔒 Authentication Model

Public Access (No Authentication Required)

• Mission information
• Basic search operations
• Metadata retrieval

Authenticated Access (Credentials Required)

• Image downloads (full, quicklook, compressed)
• Batch downloads
• Availability checks
• Download link retrieval

Token Management

• Automatic token acquisition from Copernicus Identity Service
• Token caching with expiration handling
• Graceful error handling for invalid credentials
• Support for both environment variables and parameter-based authentication

⚠️ Error Handling

The server includes comprehensive error handling for:

Authentication Errors

• Missing credentials
• Invalid credentials
• Token expiration
• Rate limiting

API Errors

• Invalid image IDs
• Unavailable products
• Network timeouts
• API quota exceeded

File System Errors

• Insufficient disk space
• Permission denied
• Invalid file paths
• Corrupted downloads

User Input Errors

• Invalid geometry formats
• Unsupported mission parameters
• Date range errors
• Invalid download types

⚡ Performance Considerations

Download Performance

• Progress Reporting: Updates every 10 seconds or 100MB
• Extended Timeouts: Up to 2 hours for large downloads
• Chunk Size: 1MB chunks for optimal throughput
• Concurrent Downloads: Configurable (default: 3 concurrent)

Timeout Configuration

The server uses appropriate timeouts for different operations:

• Small files (quicklooks): 2 minutes
• Medium files (compressed): 1 hour
• Large files (full products): 2 hours
• API requests: 1 minute

MCP Client Compatibility

• All progress sent to stderr with regular flushing
• Clients must monitor stderr for progress updates
• Connection kept alive through periodic output

Download Sizes

• Quicklooks: 100KB - 1MB (recommended for testing)
• Compressed Products: 100MB - 1GB
• Full Products: 1GB - 10GB+ (varies by mission)

Network Usage

• Start with quicklook downloads for testing
• Use max_concurrent to control bandwidth usage
• Monitor disk space for large downloads

🚨 Security Notes

Credential Safety

• Never hardcode credentials in code
• Use environment variables or secure credential stores
• Tokens are automatically refreshed and never stored permanently
• All authentication errors are logged without exposing sensitive information

Network Security

• All API calls use HTTPS with proper certificate validation
• Timeout settings prevent hanging connections

File Security

• Downloaded files use standard file permissions
• No automatic execution of downloaded content
• Cleanup operations require explicit confirmation (dry-run mode by default)

🔧 Troubleshooting

Testing Your Setup

# Test timeout fixes
python test_download_timeout.py

# Test with example downloads
python example_download_usage.py

Common Issues and Solutions

Authentication Failures

# Check if credentials are set
echo $COPERNICUS_USERNAME
echo $COPERNICUS_PASSWORD

# Test authentication directly
python -c "
import asyncio
from copernicus_mcp.server import get_auth_token
async def test():
    result = await get_auth_token()
    print('Result:', result)
asyncio.run(test())
"

Download Failures

1. Check disk space: Ensure you have sufficient space for downloads
2. Verify image ID: Use valid IDs from search results
3. Try quicklook first: Test with smaller files before downloading full products
4. Check network: Ensure stable internet connection

Search Issues

1. Date range: Use reasonable date ranges (e.g., last 30 days)
2. Geometry size: Keep search areas manageable
3. Cloud cover: Adjust cloud cover filters for optical missions

Debug Mode

Enable debug logging for detailed information:

export COPERNICUS_DEBUG_AUTH=true
python -m copernicus_mcp

Log Files

• Check application logs for detailed error messages
• Monitor download progress in real-time
• Review cleanup operations before execution

🚨 Zed Timeout Fixes

Issue Description

Zed IDE (and other MCP clients) expect MCP tools to complete quickly (typically within 30-60 seconds). However, full satellite image downloads might take hours to complete. This mismatch causes Zed to kill download processes prematurely. you can increase MCP Tool timeout in Zed settings.
