WHAT IT DOES

What delete_asset does on Unreal-MCP

AI agents call delete_asset to permanently remove resources in Unreal-MCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

From the tool's definition Tool name is 'delete_asset' and description states 'Delete an asset or directory from the Content Browser.' The verb 'Delete' combined with the action of removing assets or directories indicates irreversible data removal.

RECOMMENDED RULE

The rule that runs delete_asset safely

delete_asset Hidden

delete_asset is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
