What clone_node does on Godot
AI agents use clone_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 | — | New name (default: "name_copy") |
scene_path | string | Yes | Path to .tscn file |
parent_path | object | — | New parent (default: same as source) |
clone_source | string | Yes | Source node path to clone |
Parameters from the server's own tool schema.
Why clone_node is rated Medium
Cloning a node creates a new copy of an existing node (and its children) in the scene. This is a reversible write operation — it creates new data but does not delete or overwrite anything. The clone can be removed if unwanted. Severity is medium because misuse could duplicate complex node hierarchies or scripts in unintended ways, but it is not destructive or irreversible.

Attacks that exploit this kind of access
The rule that runs clone_node 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 clone_node, this is the rule to start with:
clone_node 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 clone_node call is checked against it from then on.
Questions about clone_node
Deep-clone a node in a scene. 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.
clone_node accepts 4 parameters: name, scene_path, parent_path, clone_source. Required: scene_path, clone_source. 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 clone_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.
clone_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 clone_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 clone_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.
clone_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.
