AI agents use set_node_scale 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
value | string | Yes | Scale: "x,y" for 2D, "x,y,z" for 3D, or "Vector2/3(...)" |
node_path | string | Yes | Node path |
scene_path | string | Yes | Path to .tscn file |
Parameters from the server's own tool schema.
This tool creates or modifies scene data reversibly by adjusting a node's scale property. It does not execute arbitrary code, delete data irreversibly, or move money, placing it firmly in Write. Medium severity reflects that incorrect scale changes could break game logic, physics, or rendering, but are easily corrected by subsequent calls.
From the tool's definition set_node_scale: Set node scale (2D/3D). This modifies node properties in the Godot scene tree, changing visual/physical scale attributes. The action is reversible (can be set to another value), but affects game object geometry and physics calculations.
Attacks that exploit this kind of access
Set node scale (2D/3D). It is categorised as a Write tool in the Godot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
set_node_scale accepts 3 parameters: value, node_path, scene_path. Required: value, node_path, scene_path. The full parameter table on this page comes from the server's own tool schema.
Register the Godot MCP server in PolicyLayer and add a rule for set_node_scale: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Godot. Nothing to install.
set_node_scale is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the set_node_scale rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for set_node_scale. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
set_node_scale is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
set_node_scale is one line of Godot's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
