## 🛠️ Development
### Available Scripts
- `npm run build`: Compile TypeScript to JavaScript
- `npm run start`: Start the MCP server
- `npm run dev`: Run in development mode with ts-node
### Environment Variables
- `GEMINI_API_KEY`: Your Google Gemini API key
- `NODEMAILER_EMAIL`: Your email address for sending emails
- `NODEMAILER_PASSWORD`: Your email app password (for Gmail, use an app password)
## 🔒 Security Notes
- Store your API keys securely
- Don't share your `.env` file
- For Gmail, use app passwords instead of your main account password
- Be careful with the content of emails sent through the system
- Never include sensitive or personal information in email examples
## 🐛 Troubleshooting
### Common Issues
1. **API Key Error**
- Verify `.env` file exists
- Check API key validity
- Ensure proper environment loading
2. **Claude Desktop Connection**
- Verify config.json syntax
- Check file paths in config
- Restart Claude Desktop
3. **Email Sending Issues**
- Check that NODEMAILER_EMAIL and NODEMAILER_PASSWORD are set correctly
- For Gmail, ensure you've created an app password
- Verify that less secure app access is enabled for non-Gmail providers
- Check recipient email address format
4. **Data Analysis Issues**
- Ensure file format is supported (.xlsx, .xls, .csv)
- Check file encoding (UTF-8 recommended)
- Verify file size is within limits
- Ensure numeric columns are properly formatted
### Debug Mode
Add `DEBUG=true` to your `.env` file for verbose logging:
```env
GEMINI_API_KEY=your_key_here
DEBUG=true
```
