The application allows users to define custom commands and arguments for MCP servers, which are then executed by the Rust backend. This presents a significant security risk as a maliciously crafted command or arguments (e.g., from a compromised marketplace server or user input) could lead to arbitrary code execution on the user's system. While the backend uses `sqlx` for database operations, preventing SQL injection, and stores credentials securely in the OS keychain (not directly in the database), the direct execution of user-provided commands is a critical vulnerability. The `tauri.conf.json` sets `csp: null`, which typically means no Content Security Policy is applied, although for a local desktop app this risk profile differs from a web application.
