WHAT IT DOES

What set_scene_group does on Godot

AI agents use set_scene_group 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
`add`	boolean	—	true to add to group, false to remove (default: true)
`group`	string	Yes	Group name
`node_path`	string	Yes	Node path within the current scene

Parameters from the server's own tool schema.

RISK

Why set_scene_group is rated Medium

This tool creates or modifies group assignments for nodes within a Godot scene hierarchy. While reversible (groups can be added or removed), it alters scene state. This is a Write operation rather than Read (it modifies data). Severity is medium because misuse could disrupt scene organization or gameplay logic, but it's reversible and doesn't delete data (not Destructive) or execute arbitrary code (not Execute).

From the tool's definition Tool description states 'Add or remove a node from a group', which modifies scene group membership.

RECOMMENDED RULE

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

set_scene_group Rate-limited

set_scene_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.

          "max": 30,

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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