create_script · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_script does on Godot MCP Server

AI agents use create_script 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 create_script needs a policy

This tool creates new files and can attach executable code (GDScript) to nodes in a Godot project. While file creation is reversible (files can be deleted), the ability to inject code into a live game project and attach it to the scene tree represents a significant write operation that could alter game behavior.

From the tool's definition Tool name is 'create_script' and description states it will 'Create a new GDScript file, optionally with initial content and optionally attach it to a node.' The verb 'create' and explicit mention of file creation indicates data modification.

create_script Rate-limited

create_script 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.
