connect_game_signal · Godot MCP Server MCP: Risk & Policy

WHAT IT DOES

What connect_game_signal does on Godot MCP Server

AI agents invoke connect_game_signal 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 connect_game_signal needs a policy

This tool attaches a listener to a running game's signal system and captures events as they fire. It triggers an external operation (signal subscription) in the live Godot runtime and returns dynamic results, making it Execute rather than a simple Read. Misuse could interfere with game logic or cause unintended side effects in the running game state.
