WHAT IT DOES

What delete_actor does on Unreal-MCP

AI agents call delete_actor 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.

RISK

Why delete_actor is rated Critical

This tool irreversibly removes actors (game objects) from an Unreal Engine level. Deletion cannot be undone programmatically by the tool itself, making this a destructive operation. While not as critical as data deletion in production systems, the loss of level design work represents significant irreversible harm.

From the tool's definition Tool name is 'delete_actor' and description states 'Delete an actor from the level by name.' The word 'delete' combined with the irreversible removal of game objects from a level indicates destructive action.

RECOMMENDED RULE

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

delete_actor Hidden

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

The button opens the PolicyLayer dashboard: create your workspace, connect Unreal-MCP, apply this rule, and every delete_actor call is checked against it from then on.
