The server correctly uses environment variables for sensitive credentials (Canvas API token, SIO username/password, admin webhook URL), which is a strong security practice. Input validation is performed using Zod schemas for tool calls, reducing the risk of malformed inputs. The Playwright browser scraping, while powerful, is executed with internally defined code, mitigating direct user injection risks. However, user data (profiles, tasks, kanban state) is stored directly on the local file system as JSON files (`mcp-server/data/`), which is not ideal for robust security or scalability in a production environment, as a server compromise could expose all user data and managing access controls/encryption for files can be complex. Path traversal for user data files is mitigated by the userId extraction regex, which prevents `../` in path segments.
