WHAT IT DOES

What import_asset does on Godot MCP Unified

WHY IT NEEDS A POLICY

Why import_asset needs a policy

This tool creates new data (asset files) within the project structure, which is reversible (assets can be deleted). It does not execute arbitrary code, delete existing data, or move financial resources. Write category applies because it modifies project state by introducing new assets.

From the tool's definition Tool description states 'Copy an external asset file into a Godot project' — a file creation/addition operation. Godot's automatic import means the tool modifies project state by adding new resources.
