WHAT IT DOES

What create_vehicle_body does on Godot

AI agents use create_vehicle_body 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.

WHY IT NEEDS A POLICY

Why create_vehicle_body needs a policy

The tool creates new game objects (VehicleBody3D nodes and child VehicleWheel nodes) within a Godot scene, which is a Write operation—it modifies the project state but can be undone (deleted). It does not execute arbitrary code, delete data irreversibly, or trigger external side effects beyond the Godot editor itself.

From the tool's definition Tool name 'create_vehicle_body' and description 'Create a VehicleBody3D with VehicleWheel nodes' explicitly indicates creation of scene nodes in Godot Engine. This is a reversible modification to the game project structure.

Verdict

create_vehicle_body Rate-limited

create_vehicle_body 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.
