WHAT IT DOES

What set_statetree_state_property does on Unreal-MCP

AI agents use set_statetree_state_property 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 set_statetree_state_property is rated Medium

The tool modifies StateTree state properties, which is a reversible write operation affecting game logic configuration. No description provided limits confidence slightly, but the naming convention and server context clearly indicate data modification rather than deletion or execution.

From the tool's definition Tool name 'set_statetree_state_property' indicates modification of StateTree properties in Unreal Engine 5. The 'set_' prefix explicitly denotes a write/mutation operation.

RECOMMENDED RULE

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

set_statetree_state_property Rate-limited

set_statetree_state_property 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.
