Why set_viewport_camera needs a policy

The name suggests adjusting the editor viewport camera position/orientation, which is a non-destructive UI/view change with no data modification, code execution, or financial implications. However, the empty description lowers confidence. Based on the name alone, this appears to be a Read/Write-adjacent view manipulation with minimal blast radius.

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

POLICY

How to control set_viewport_camera

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 set_viewport_camera:

policy.json

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

set_viewport_camera 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.
