import_avatar · Clo3d MCP: Risk & Policy

WHAT IT DOES

What import_avatar does on Clo3d

AI agents use import_avatar to create or update resources in Clo3d — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Clo3d environment.

WHY IT NEEDS A POLICY

Why import_avatar needs a policy

The tool creates or modifies project state by loading an avatar asset into CLO3D, similar to uploading or adding content. This is a Write action (reversible; the avatar can be removed or replaced). It is not Read (it changes state), Execute (no arbitrary code/command execution), Destructive (reversible), Financial (no money involved), or Other.

From the tool's definition import_avatar imports an avatar file into the scene — this modifies the scene's state by adding content, which is a reversible write operation.

Verdict

import_avatar Rate-limited

import_avatar stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
