vfx_masks_or · vidMagik- MCP: Risk & Policy

WHAT IT DOES

What vfx_masks_or does on vidMagik-mcp

AI agents invoke vfx_masks_or to trigger actions in vidMagik-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 vfx_masks_or needs a policy

This tool executes a video compositing operation (logical OR on masks) within a video editing pipeline. It is not a simple read, nor does it delete or move money. It triggers a processing action whose result depends on the input masks, placing it in the Execute category. Severity is medium given it operates on video data but has limited blast radius compared to destructive or financial operations.

From the tool's definition 'Logical OR of masks' — performs a compositing operation combining mask data, triggering a video processing/transformation operation
