pix4d_focus · PIX4Dmatic MCP: Risk & Policy

WHAT IT DOES

What pix4d_focus does on PIX4Dmatic MCP

AI agents invoke pix4d_focus to trigger actions in PIX4Dmatic MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why pix4d_focus needs a policy

Focusing a window triggers an external GUI operation that changes the state of the application window manager. It is not purely reading data — it actively brings the application window to the foreground. While low impact, it falls under Execute as it triggers an external operation on the OS/GUI environment. Severity is low because the blast radius of misuse is minimal.
