WHAT IT DOES

What create_asset does on Cocos

AI agents use create_asset 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 create_asset is rated Medium

This tool creates new assets or folders in the project, which is a reversible write operation. While it modifies the project state, asset creation can be undone (typical in editor undo/redo systems, evidenced by 'begin_undo_recording' and 'cancel_undo_recording' sibling tools).

From the tool's definition Tool name is 'create_asset' and description states 'Create a new asset file or folder', indicating it creates new data structures within the Cocos Creator project.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_asset Rate-limited

create_asset 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 create_asset call is checked against it from then on.
