create_script · GameDevBench MCP: Risk & Policy

WHAT IT DOES

What create_script does on GameDevBench MCP

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

WHY IT NEEDS A POLICY

Why create_script needs a policy

The tool creates or modifies script files within a game development environment. This is a Write operation because scripts can be created and modified reversibly. While the description is empty, the naming pattern and sibling tools ('delete_script', 'execute_blender_code') provide strong contextual evidence.

From the tool's definition Tool name 'create_script' combined with sibling tools 'delete_script' and 'execute_blender_code' indicate this creates script files. The server context (Godot game engine interaction via AppleScript) supports script creation as a reversible write operation.

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.
