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 (reversible write operation) rather than executing code directly. However, it generates GDScript code that could contain malicious logic, giving it high severity due to the indirect execution risk when the created scripts are later loaded by the Godot engine. The write nature dominates over execute because the tool itself does not run the code — it only creates the file.

From the tool's definition Tool description states 'Create a new GDScript file' — this is a file creation operation that modifies the project structure by adding new code files. GDScript files are executable code resources in Godot projects.

Verdict

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.
