retexture_to_youtube · Meshy Youtube MCP: Risk & Policy

WHAT IT DOES

What retexture_to_youtube does on Meshy Youtube

AI agents use retexture_to_youtube to create or update resources in Meshy Youtube — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Meshy Youtube environment.

WHY IT NEEDS A POLICY

Why retexture_to_youtube needs a policy

The tool performs two primary operations: (1) retexturing modifies an existing 3D model's appearance (reversible data modification), and (2) uploading to YouTube is a write action that posts content to an external platform. While it involves external API interactions and potential reach/visibility implications, it does not execute arbitrary code, delete data permanently, or move money.

From the tool's definition re-texture an existing model -> turntable -> YouTube video; the tool modifies model data (retexturing) and uploads content to YouTube, which is a platform write operation
