Why viewport_orbit needs a policy

The name 'viewport_orbit' suggests a camera/view manipulation action within the UEFN editor viewport (orbiting the camera around a point), which is a non-destructive UI/view operation. However, with no description provided, confidence is low. Based on name alone, this appears to be a Read-adjacent or Other category action that changes the editor's view state without modifying any data.

From the tool's definition Tool name is 'viewport_orbit'; description is empty or uninformative.

POLICY

How to control viewport_orbit

PolicyLayer is an MCP gateway — it sits between your AI agents and Uefn, and nothing reaches the server without passing your rules. This is the rule we recommend for viewport_orbit:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "viewport_orbit": {
      "limits": [
        {
          "counter": "viewport_orbit_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

viewport_orbit gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register Uefn — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
