The server demonstrates good security practices including using environment variables for sensitive API keys, hashing passwords (though the login_user tool in main.py claims 'not implemented yet' for password-based login, auth.py shows a login_user implementation that hashes passwords), and proper session management with UUIDs. File uploads are processed using temporary files and a maximum size limit is enforced (10MB). Authentication checks are performed for most tool calls. No direct 'eval' or obvious shell injection vulnerabilities were found. Potential areas for further hardening could include more explicit output sanitization before rendering on the frontend to prevent XSS (a common web concern), and robust input validation for all string-based arguments, as well as mitigating prompt injection risks inherent in LLM interactions.
