mcp-server

The server correctly uses environment variables for sensitive API keys (e.g., GMAIL_CLIENT_ID, GDRIVE_CLIENT_SECRET), preventing hardcoded secrets. No direct use of `eval` or `child_process` with unsanitized user input was found, reducing command injection risks. The HTTP routes (via Express) are optional and not enabled by default via `npm start`; if enabled, proper authentication and authorization would be critical. Google Drive webhook integration is mentioned as a placeholder, which would require careful security implementation (e.g., signature verification) when fully realized. Input validation in `lib/validators.js` helps prevent malformed data, but robust input sanitation is key for all text processing functions. Overall, the foundational codebase is relatively secure for its stdio-based operation.
