WHAT IT DOES

What navigation_add_obstacle does on Godot

AI agents use navigation_add_obstacle to create or update resources in Godot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.

RISK

Why navigation_add_obstacle is rated Medium

The 'add' verb combined with 'obstacle' in a Godot game engine context indicates the tool creates or inserts a new navigation obstacle entity into the game world, modifying scene state reversibly. This is a Write operation rather than Execute because it adds a discrete game object rather than running arbitrary code.

From the tool's definition Tool name 'navigation_add_obstacle' indicates creation of a game engine object; 'add' prefix suggests a write/create operation that modifies the scene or navigation system. No description provided, limiting certainty.

RECOMMENDED RULE

The rule that runs navigation_add_obstacle safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For navigation_add_obstacle, this is the rule to start with:

navigation_add_obstacle Rate-limited

navigation_add_obstacle stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
