render_turntable · Meshy Youtube MCP: Risk & Policy

WHAT IT DOES

What render_turntable does on Meshy Youtube

AI agents invoke render_turntable to trigger actions in Meshy Youtube. 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 render_turntable needs a policy

This tool executes an external application (Blender) to render a 3D model into image frames. It triggers an external process whose effects depend on arguments (the GLB file and render settings). It writes output PNG frames as a side effect, but the primary action is executing Blender to perform rendering, making Execute the most appropriate category.
