WHAT IT DOES

What list_statetree_node_types does on Unreal-MCP

AI agents call list_statetree_node_types to retrieve information from Unreal-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_statetree_node_types is rated Low

This tool only retrieves and enumerates available StateTree node types from Unreal Engine's schema. It does not modify, execute, delete, or create any assets or engine state. The action is purely informational and read-only, making it a low-severity Read category tool.

From the tool's definition Tool name contains 'list' and description states 'List available task/evaluator/condition types for the StateTree's schema' — this is a query operation that retrieves schema information with no side effects.
