WHAT IT DOES

What tripo3d_upload_image does on Tripo3D MCP

AI agents use tripo3d_upload_image to create or update resources in Tripo3D MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tripo3D MCP environment.

WHY IT NEEDS A POLICY

Why tripo3d_upload_image needs a policy

Upload operations typically create or store data (Write category). Given the context of a 3D model generation API, uploading an image likely stores it as input for downstream 3D processing. This is reversible and has no destructive or financial implications.
