create_tilemap_layer · Godot MCP Unified MCP: Risk & Policy

WHAT IT DOES

What create_tilemap_layer does on Godot MCP Unified

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

WHY IT NEEDS A POLICY

Why create_tilemap_layer needs a policy

Creating a TileMapLayer node modifies the scene structure by adding a new node. This is a Write operation because it creates scene data that can be subsequently modified or deleted. It is not Destructive (reversible via undo/deletion), not Execute (no arbitrary code execution), and not Read (causes persistent changes).

From the tool's definition Tool name is 'create_tilemap_layer' and description states it 'Create[s] a TileMapLayer node in a scene' — this is node/asset creation within a Godot scene, which is reversible scene modification.
