unifi_ptz_move · Garza Home MCP: Risk & Policy

WHAT IT DOES

What unifi_ptz_move does on Garza Home MCP

AI agents invoke unifi_ptz_move to trigger actions in Garza Home 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 unifi_ptz_move needs a policy

PTZ control drives physical camera hardware (panning, tilting, zooming), which is an external operation with real-world effects. It doesn't merely read data, nor does it delete anything, but it executes commands that move physical security camera equipment. Misuse could reposition cameras away from monitored areas, creating security blind spots — hence high severity.

From the tool's definition PTZ control — PTZ stands for Pan-Tilt-Zoom, indicating this tool actively controls physical camera movement/positioning
