WHAT IT DOES

What assert_node_exists does on Mcp Godot Desenvolvimento

AI agents call assert_node_exists to retrieve information from Mcp Godot Desenvolvimento without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why assert_node_exists is rated Low

The tool checks/verifies whether a node exists in the scene. This is a read-only assertion with no side effects. The description is minimal but 'Verifica' (verifies) clearly implies a query operation. Low severity as misuse would only yield false information, not modify or destroy anything.

From the tool's definition 'Verifica se no existe na cena' — 'Verifica' means 'Verifies/Checks', indicating a read/query operation to assert node existence in the scene
