WHAT IT DOES

What launch_editor does on Godot MCP

AI agents invoke launch_editor to trigger actions in Godot 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 launch_editor needs a policy
