The server uses parameterized queries for SQLite operations, effectively preventing SQL injection. File paths are handled safely with `os.path.join`. No explicit hardcoded secrets or dangerous functions like `eval` or `os.system` are present. Security relies on the underlying `fastmcp` framework's robustness and appropriate network configuration when exposed via HTTP. Future enhancements for user authentication and authorization would be critical for production use in a multi-user environment.
