WHAT IT DOES

What move_array_element does on Cocos

AI agents use move_array_element 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 move_array_element is rated Medium

This action creates or modifies data reversibly—array reordering is non-destructive and can be undone via the undo system (evidenced by begin_undo_recording and cancel_undo_recording tools on the same server). It does not delete data, execute arbitrary code, or trigger financial transactions.

From the tool's definition The tool name and description indicate it moves array element position. Within Cocos Creator editor context, this modifies data structures (array ordering) reversibly without permanent deletion.

RECOMMENDED RULE

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

move_array_element Rate-limited

move_array_element 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.
