AI agents use group 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.
The tool can both add and remove node groups, which are write/modify operations on the scene graph. Removal of groups could be somewhat irreversible in practice but groups are generally reassignable, making this a Write-level operation. The 'list' sub-action is a Read, but the most severe applicable category is Write due to add/remove capabilities.
From the tool's definition 'add, or remove node groups' — modifies group membership of nodes
Documented attack patterns abuse exactly the kind of access group 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 group:
{
"version": "1",
"default": "deny",
"tools": {
"group": {
"limits": [
{
"counter": "group_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}group 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.

List, add, or remove node groups. 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 group: 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.
group 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 group 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 group. 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.
group 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.
