# 📊 Complete Workflow Example
```python
# 1. Search for images
search_results = search_copernicus_images(
geometry=[-122.4194, 37.7749], # San Francisco
geometry_type="point",
mission="sentinel-2",
start_date="2024-01-01",
end_date="2024-01-31",
max_cloud_cover=30,
max_results=5
)
# 2. Extract image IDs
image_ids = [img["Id"] for img in search_results.get("products", [])]
# 3. Check availability
availability = check_download_availability(image_ids[:2])
# 4. Download quicklooks for available images
for image_id in image_ids[:2]:
download_image(
image_id=image_id,
mission="sentinel-2",
download_type="quicklook"
)
# 5. List downloaded files
files = list_downloaded_files(
download_dir="downloads",
file_type="quicklook"
)
# 6. Get statistics
stats = get_download_statistics()
```
# 🔒 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**
```bash
# Test timeout fixes
python test_download_timeout.py
# Test with example downloads
python example_download_usage.py
```
## Common Issues and Solutions
### Authentication Failures
```bash
# 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:
```bash
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.
