WHAT IT DOES

What save_asset_meta does on Cocos

AI agents use save_asset_meta 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 save_asset_meta is rated Medium

Saving asset metadata is a reversible write operation that modifies asset properties without destroying data. It does not execute arbitrary code, delete assets, or involve financial operations. However, in a game engine editor context, uncontrolled metadata modifications could corrupt assets or introduce unintended behavior (medium severity).

From the tool's definition Tool name 'save_asset_meta' and description 'Save asset meta information' indicate modification of asset metadata.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

save_asset_meta Rate-limited

save_asset_meta 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 save_asset_meta call is checked against it from then on.
