WHAT IT DOES

What duplicate_prefab does on Cocos

AI agents use duplicate_prefab 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 duplicate_prefab is rated Medium

Duplicating a prefab creates a new copy of an existing asset. This is a reversible write operation — it creates new data without destroying anything. Misuse could clutter the project with unwanted copies, but no data is lost.

RECOMMENDED RULE

The rule that runs duplicate_prefab 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 duplicate_prefab, this is the rule to start with:

duplicate_prefab Rate-limited

duplicate_prefab 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Cocos, apply this rule, and every duplicate_prefab call is checked against it from then on.
