WHAT IT DOES

What set_node_owner does on Godot MCP Server

AI agents use set_node_owner 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_node_owner needs a policy

This tool modifies node properties in the Godot scene tree—specifically the owner relationship, which is a fundamental attribute used during scene serialization. While the change is reversible (owner can be reassigned), it directly affects game scene structure and will persist when scenes are saved. This is a Write operation: it creates or modifies data reversibly.

From the tool's definition Tool name 'set_node_owner' and description states it 'Set the owner of a node (required for saving packed scenes)', indicating modification of node ownership metadata that affects scene persistence.
