THE RISK

Low Risk

Why spline_to_verse_patrol needs a policy

The tool name suggests converting a spline to a Verse patrol path in UEFN, which would likely be a Write operation (creating/modifying data). However, with no description, the exact behavior is unknown. Given the sibling tools context (UEFN editor operations), this is likely a Write or Execute action. Confidence is low due to empty description. Defaulting to Other with medium severity as a precaution.

From the tool's definition Tool name is 'spline_to_verse_patrol' but description is empty and uninformative.

POLICY

How to control spline_to_verse_patrol

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 spline_to_verse_patrol:

policy.json

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

spline_to_verse_patrol 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.
