WHAT IT DOES

What set_reference_image_opacity does on Cocos

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

RISK

Why set_reference_image_opacity is rated Medium

This tool creates or modifies editor state (reference image opacity) reversibly without destroying data or executing arbitrary code. While it affects visual properties in the editor, the change is non-destructive and can be undone. It does not execute code, trigger external operations, delete data, or involve financial transactions.

From the tool's definition set_reference_image_opacity modifies the opacity property of a reference image in Cocos Creator, which is a reversible change to scene state.

RECOMMENDED RULE

The rule that runs set_reference_image_opacity safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Cocos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_reference_image_opacity, this is the rule to start with:

set_reference_image_opacity Rate-limited

set_reference_image_opacity 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.
