WHAT IT DOES

What remove_statetree_parameter does on Unreal-MCP

AI agents call remove_statetree_parameter 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_parameter is rated Critical

Removing a parameter from a StateTree is a destructive operation: the parameter and any data it holds are deleted. This is not easily undone without version control, and dependent logic referencing that parameter may break. No indication of soft-delete or reversible behavior.

From the tool's definition 'Remove a tree-level parameter by name' — removal is an irreversible deletion of a named parameter from the StateTree

RECOMMENDED RULE

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

remove_statetree_parameter Hidden

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