The server demonstrates a strong focus on security. It uses Windows DPAPI for secure API key storage (with graceful fallback to environment variables/file permissions on other OS), implements comprehensive log sanitization to prevent injection and sensitive data leakage, includes robust security headers (X-Frame-Options, CSP, etc.) via middleware, and employs request size limiting to mitigate DoS attacks. The internal authentication uses HMAC for secure inter-MCP communication. API keys are loaded securely and never hardcoded or exposed to end-users directly. Filename generation includes sanitization to prevent path traversal. Overall, security appears to be a high priority.
