WHAT IT DOES

What node_add does on Godot

AI agents use node_add 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 node_add is rated Medium

Adding nodes to a Godot scene creates or modifies project structure reversibly. This is a Write operation—data is created but can be undone (deleted). It does not execute arbitrary code, delete data irreversibly, or move financial assets.

From the tool's definition Tool name 'node_add' indicates creation of a node (scene element) in the Godot editor. Sibling tools like 'animation_create', 'audio_add_stream_player', and 'autoload_add' all perform additive operations consistent with Write category.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs node_add 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 node_add, this is the rule to start with:

node_add Rate-limited

node_add 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every node_add call is checked against it from then on.

Can I rate-limit node_add? +
