AI agents use editor_add_node 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 |
|---|---|---|---|
name | object | — | Node name (auto-generated if omitted) |

Parameters from the server's own tool schema.
This tool creates (adds) a new node to an open Godot scene, which is a reversible modification of the scene structure. It falls under Write category as it modifies project state without irreversible destruction or code execution. Severity is medium because uncontrolled node addition could corrupt scene structure or bloat projects, but changes are typically undoable via Godot's undo system.
From the tool's definition Tool name 'editor_add_node' and description 'Add a node to the currently open scene in editor' indicate creation of a new scene element.
Attacks that exploit this kind of access
Add a node to the currently open scene in editor. 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.
editor_add_node accepts 4 parameters: name, type, parent, properties. Required: type. 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 editor_add_node: 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.
editor_add_node 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 editor_add_node 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 editor_add_node. 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.
editor_add_node 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.
editor_add_node 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.
