godot_save_scene · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What godot_save_scene does on Godot MCP Server

AI agents use godot_save_scene 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_save_scene needs a policy

This tool creates or modifies scene files on disk, which is reversible (scenes can be edited or restored from version control). It does not delete or irreversibly destroy data, so it is Write rather than Destructive. The severity is high because an AI agent could overwrite critical scene files, corrupt game projects, or save malicious modifications to scenes that affect game logic.

From the tool's definition Tool description states 'Saves the specified scene (or active scene) to disk' with optional 'save_as' parameter for Save As functionality. This modifies files on disk by persisting scene data.
