godot-screenshot · GameDevBench MCP: Risk & Policy

WHAT IT DOES

What godot-screenshot does on GameDevBench MCP

AI agents invoke godot-screenshot to trigger actions in GameDevBench MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why godot-screenshot needs a policy

This tool does more than passively read data; it executes an external application launch via AppleScript and then performs a display capture. Launching processes and controlling applications via AppleScript constitutes execution of external operations. The blast radius is moderate — it could launch unintended application instances or capture sensitive screen content, but it does not modify or delete persistent data.

From the tool's definition 'Launch Godot editor on specified display and take a screenshot' — the tool actively launches an application (Godot editor) and captures a screenshot using AppleScript
