The Electron application implements good security practices, such as context isolation and disabling Node.js integration in renderer processes. It carefully manages new window creation, restricting external URLs to the system's default browser and explicitly allowing only internal OAuth authorization popups. The backend Hono server acts as a proxy for external OAuth and widget content. While OAuth proxying is common for desktop applications to bypass CORS, it's critical that the underlying MCP SDK and client-side logic rigorously validate target URLs to prevent Server-Side Request Forgery (SSRF) vulnerabilities. The inclusion of an ngrok-based tunnel feature, while providing functionality to expose local services, inherently increases the attack surface, though it integrates with WorkOS authentication to manage access.
