WHAT IT DOES

What import_assets_batch does on Unreal-MCP

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

RISK

Why import_assets_batch is rated Medium

The tool creates or adds assets to the Unreal Engine project, which is a reversible modification (assets can be deleted or replaced). This qualifies as Write rather than Read (it modifies state) or Destructive (imports are not irreversible—imported assets can be removed).

From the tool's definition Tool name 'import_assets_batch' indicates bulk import of game assets into Unreal Engine 5 editor. No description provided, but batch import operations typically create or add new assets to the project.

RECOMMENDED RULE

The rule that runs import_assets_batch safely

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

import_assets_batch Rate-limited

import_assets_batch 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.
