open_scene · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What open_scene does on Godot MCP Server

AI agents invoke open_scene to trigger actions in Godot MCP Server. 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 open_scene needs a policy

Opening a scene triggers an external operation in the Godot editor application via WebSocket, changing the editor's active state. This is not purely reading data—it causes a side effect in the external application (loading and displaying a scene). It fits Execute as it triggers an external operation in the editor environment.

Verdict

open_scene Rate-limited

open_scene stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
