THE RISK

Medium Risk

Why verse_gen_game_skeleton needs a policy

This tool creates new content (a game device skeleton) in the UEFN editor. It generates/writes new assets and logic structures but does not delete anything, execute arbitrary code, or involve financial transactions. The blast radius is medium as it could create unwanted scaffolding in a live editor project.

From the tool's definition Generate a full game device skeleton with round logic, timer, scoreboard, spawn pads

POLICY

How to control verse_gen_game_skeleton

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 verse_gen_game_skeleton:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "verse_gen_game_skeleton": {
      "limits": [
        {
          "counter": "verse_gen_game_skeleton_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

verse_gen_game_skeleton 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.

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.
