Create Control nodes, reusable UI templates, themes, and automatic signal wiring
AI agents use ui to create or update resources in Godot Devtool — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot Devtool environment.
This tool creates new UI elements and templates in a reversible manner (nodes can be deleted, templates can be removed, signal wiring can be unwired). It does not execute arbitrary code, delete data irreversibly, or move money. The blast radius is medium because incorrect UI creation could break the project's interface or add unwanted signal handlers, but changes are reversible via undo/deletion.
From the tool's definition Tool description states it will "Create Control nodes, reusable UI templates, themes, and automatic signal wiring" — explicit use of "Create" indicates data/asset creation within the Godot project structure.
Documented attack patterns abuse exactly the kind of access ui gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Godot Devtool, and nothing reaches the server without passing your rules. This is the rule we recommend for ui:
{
"version": "1",
"default": "deny",
"tools": {
"ui": {
"limits": [
{
"counter": "ui_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ui 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.

Create Control nodes, reusable UI templates, themes, and automatic signal wiring. It is categorised as a Write tool in the Godot Devtool MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Godot Devtool MCP server in PolicyLayer and add a rule for ui: 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 Devtool. Nothing to install.
ui 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 ui 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 ui. 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.
ui is provided by the Godot Devtool MCP server (wangdiandao/godot-devtool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
