call_game_node_method · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What call_game_node_method does on Godot MCP Server

AI agents invoke call_game_node_method 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 call_game_node_method needs a policy

This tool executes arbitrary methods on game nodes at runtime. The effects are entirely determined by which method is called and its arguments, potentially triggering any game logic, modifying state, or causing side effects within the running game. This is an Execute-category action with high severity since an AI agent could invoke destructive or unintended game behaviors depending on what methods are available.
