WHAT IT DOES

What set_game_node_property does on Godot MCP Server

AI agents use set_game_node_property to create or update resources in Godot MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot MCP Server environment.

WHY IT NEEDS A POLICY

Why set_game_node_property needs a policy

This tool modifies a property of a node in a running Godot game session. It creates or updates data (node properties) in a reversible way — properties can be changed again. This is a Write operation. Severity is medium because misuse could corrupt game state or cause unexpected behavior in a running game, but it is not irreversible and limited to the game session context.
