WHAT IT DOES

What godot_add_node does on Godot MCP Server

AI agents use godot_add_node 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 godot_add_node needs a policy

Adding nodes to a Godot scene is a creative/modifying operation that alters project state (Write category). Severity is medium because while this creates scene structure that persists in the project file, it is reversible (nodes can be removed via godot_remove_node). The blast radius is limited to scene composition rather than data deletion or financial impact.

From the tool's definition Tool description explicitly states 'Adds a new node' which creates a new entity in the scene tree. This is a reversible modification to project structure.
