WHAT IT DOES

What remove_statetree_transition does on Unreal-MCP

AI agents call remove_statetree_transition 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 remove_statetree_transition is rated Critical

The tool performs an irreversible deletion of a game logic component (a state transition). Removing a transition from a StateTree is a destructive operation that modifies the behavior graph permanently. While the data structure itself (the StateTree) may persist, the specific transition link is permanently removed, requiring manual re-creation to restore.

From the tool's definition Tool name 'remove_statetree_transition' uses the verb 'remove', which irreversibly deletes a transition from a state in Unreal Engine's StateTree system. This action cannot be undone without manual recreation.
