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:

GEMINI_API_KEY=your_key_here
DEBUG=true
