WHAT IT DOES

What material_bulk_swap does on Uefn

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

RISK

Why material_bulk_swap is rated Medium

The name 'material_bulk_swap' strongly implies batch replacement of materials on actors/assets in the UEFN editor. 'Bulk' operations affecting many objects at once are reversible in principle (materials can be reassigned), placing this in Write. However, the empty description lowers confidence, and the bulk nature means misuse could affect many assets simultaneously, warranting high severity.

From the tool's definition Tool name 'material_bulk_swap' — description is empty and uninformative.

RECOMMENDED RULE

The rule that runs material_bulk_swap safely

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

material_bulk_swap Rate-limited

material_bulk_swap 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.
