Security Notes
The project demonstrates a strong focus on security, especially in the database and Gmail servers. The database server hardcodes 'localhost' for database connections, explicitly prevents SQL injection through parameterized queries, and blocks dangerous SQL keywords (INSERT, UPDATE, DELETE, etc.). The Gmail server uses Google OAuth 2.0, handles credentials and tokens securely with explicit warnings not to commit them, and includes a safety limit for email deletion. All API keys are loaded from environment variables, preventing hardcoded secrets. Error handling for API rate limits and invalid keys is robust across all servers.
