select_node · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What select_node does on Godot MCP Server

AI agents invoke select_node 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 select_node needs a policy

This tool triggers an editor UI action (selecting a node in the scene tree panel), which is an external operation in the Godot editor. It doesn't purely read data or write/modify data, but rather interacts with the editor's state by changing the selection. This falls under Execute as it triggers an external operation in the editor. The blast radius is low since selection is a non-destructive UI state change.

Verdict

select_node Rate-limited

select_node 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.
