WHAT IT DOES

What vfx_painting does on vidMagik-mcp

AI agents invoke vfx_painting 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_painting needs a policy

This tool applies a painting visual effect to video clips using MoviePy. It triggers an external video processing operation whose output depends on the input arguments. The description is minimal and uninformative, lowering confidence. No data is irreversibly deleted, no financial transaction occurs, and it's more than a passive read — it executes a transformation pipeline.
