WHAT IT DOES

What set_node_groups does on Godot

AI agents use set_node_groups 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
`path`	string	Yes	Node path in the scene tree (e.g. 'Player/Sprite2D'). Use just the node name for root-level children (e.g. 'Player'), or empty string '' for the scene root itse
`groups`	array	Yes	List of group names

Parameters from the server's own tool schema.

RISK

Why set_node_groups is rated Medium

This tool modifies node metadata (group assignments) within a Godot project. While reversible and not destructive, it is a Write operation that changes scene structure. Severity is medium because incorrect group assignments could break scene logic or gameplay mechanics, but changes can be undone.

From the tool's definition "Set the groups a node belongs to (replaces existing groups)" - modifies node group membership, which is reversible state modification in a Godot scene.

RECOMMENDED RULE

The rule that runs set_node_groups 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 set_node_groups, this is the rule to start with:

set_node_groups Rate-limited

set_node_groups 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.

  "default": "deny",
  "tools": {
    "set_node_groups": {
      "limits": [
        {
          "counter": "set_node_groups_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every set_node_groups call is checked against it from then on.

FAQ

Questions about set_node_groups

What does the set_node_groups tool do? +

Set the groups a node belongs to (replaces existing groups). 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.

What parameters does set_node_groups accept? +

set_node_groups accepts 2 parameters: path, groups. Required: path, groups. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on set_node_groups? +

Register the Godot MCP server in PolicyLayer and add a rule for set_node_groups: 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.

What risk level is set_node_groups? +

set_node_groups is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_node_groups? +

Yes. Add a rate_limit block to the set_node_groups 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.

How do I block set_node_groups completely? +

Set action: deny in the PolicyLayer policy for set_node_groups. 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.

What MCP server provides set_node_groups? +

set_node_groups is provided by the Godot MCP server (@keeveeg/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
