WHAT IT DOES

What create_world does on Godot

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

`environment_path`	object	—	Path to Environment .tres to attach

Parameters from the server's own tool schema.

WHY IT NEEDS A POLICY

Why create_world needs a policy

The tool creates a new World3D resource file, which is a write operation that modifies the project state by adding a new asset. It is reversible (the file can be deleted) and does not execute arbitrary code, delete existing resources irreversibly, or move money.

From the tool's definition Tool name 'create_world' and description 'Create World3D .tres' indicate creation of a new resource file (.tres is Godot's text-serialized resource format). This is a reversible write operation that creates data artifacts in the Godot project.
