+    
+    analyze_pdfs = app["analyze_uploaded_statements"]
+    pdf_result = analyze_pdfs.remote(pdf_contents)
+    
+    # Combine analysis data
+    combined_analysis = {
+        **email_result["analysis"],
+        "additional_transactions": pdf_result["total_transactions"]
+    }
+    
+    # Get AI analysis
+    get_analysis = app["get_ai_analysis"]

+        combined_analysis,
+        "What are my top 3 spending categories?",
+        "sambanova"
+    )
+    
+    print("Claude Analysis:", claude_analysis["ai_analysis"])
+    print("SambaNova Analysis:", sambanova_analysis["ai_analysis"])
+
+# Run the analysis
+asyncio.run(analyze_finances())
+```
+

+## Monitoring and Logs
+
+### View Logs
+```bash
+modal logs spend-analyzer-mcp-bmt
+```
+
+### Monitor Functions
+```bash
+modal stats spend-analyzer-mcp-bmt
+```
+
+### View Volumes
+```bash
+modal volume list
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Import Errors**: Ensure all dependencies are in the Modal image
+2. **Secret Access**: Verify secrets are created with correct names
+3. **PDF Processing**: Check file permissions and password requirements
+4. **API Limits**: Monitor usage for both Claude and SambaNova
+
+### Debug Mode
+
+Enable debug logging in Modal functions:
+
+```python
+import logging
+logging.basicConfig(level=logging.DEBUG)
+```
+
+### Local Testing
+
+Test functions locally before deployment:
+
+```bash
+modal run modal_deployment.py::main
+```
+
+## Security Considerations
+
+1. **API Keys**: Store in Modal secrets, never in code
+2. **Email Passwords**: Use app-specific passwords
+3. **PDF Data**: Processed in memory, not stored permanently
+4. **User Data**: Isolated by user ID in persistent storage
+
+## Cost Optimization
+
+1. **Function Timeouts**: Set appropriate timeouts for each function
+2. **Memory Allocation**: Adjust based on PDF processing needs
+3. **API Provider**: Choose between Claude (quality) and SambaNova (cost)
+4. **Batch Processing**: Process multiple PDFs in single function call
+
+## Scaling
+
+Modal automatically handles scaling based on demand:
+
+- **Cold Starts**: ~2-3 seconds for new containers
+- **Warm Containers**: Sub-second response times
+- **Concurrent Requests**: Automatically scaled
+- **Resource Limits**: Configurable per function
+
+## Integration with MCP
+
+The deployment includes a webhook endpoint for MCP integration:
+
+```
+POST https://your-modal-app.modal.run/mcp_webhook
+```
+
+This enables integration with Claude Desktop and other MCP clients.
+
+## Support
+
+For deployment issues:
+
+1. Check Modal logs and documentation
+2. Verify API key permissions
+3. Test with minimal examples
+4. Contact Modal support for platform issues
+
+## Next Steps
+
+After successful deployment:
+
+1. Test all functions with real data
+2. Set up monitoring and alerts
+3. Configure backup strategies
+4. Implement additional security measures
+5. Scale based on usage patterns

+        ## For Local Development:
+        
+        ### Windows (Command Prompt):
+        ```cmd
+        set CLAUDE_API_KEY=your-claude-api-key-here
+        set SAMBANOVA_API_KEY=your-sambanova-api-key-here
+        set LM_STUDIO_URL=http://localhost:1234/v1
+        set OLLAMA_URL=http://localhost:11434
+        ```
+        
+        ### Windows (PowerShell):
+        ```powershell
+        $env:CLAUDE_API_KEY="your-claude-api-key-here"
+        $env:SAMBANOVA_API_KEY="your-sambanova-api-key-here"
+        $env:LM_STUDIO_URL="http://localhost:1234/v1"
+        $env:OLLAMA_URL="http://localhost:11434"
+        ```
+        
+        ### macOS/Linux (Bash):
+        ```bash
+        export CLAUDE_API_KEY="your-claude-api-key-here"
+        export SAMBANOVA_API_KEY="your-sambanova-api-key-here"
+        export LM_STUDIO_URL="http://localhost:1234/v1"
+        export OLLAMA_URL="http://localhost:11434"
+        ```
+        
+        ### .env File (Recommended):
+        Create a `.env` file in your project directory:
+        ```
+        CLAUDE_API_KEY=your-claude-api-key-here
+        SAMBANOVA_API_KEY=your-sambanova-api-key-here
+        LM_STUDIO_URL=http://localhost:1234/v1
+        OLLAMA_URL=http://localhost:11434
+        ```
+        
+        ## Security Best Practices:
+        1. Never commit API keys to version control
+        2. Use different keys for development and production
+        3. Regularly rotate your API keys
+        4. Monitor API usage for unusual activity
+        5. Use least-privilege access principles
