THE RISK

Low Risk

Why verse_template_get needs a policy

This tool retrieves template source code for inspection and customization by the user—a pure read operation with no side effects on the UEFN editor state. While the retrieved code may later be deployed, the tool itself only fetches data. The low severity reflects that reading templates poses minimal risk unless the templates themselves contain malicious code (which is a content risk, not a tool capability risk).

From the tool's definition Tool name 'verse_template_get' and description 'Get full Verse source for a named template' indicate data retrieval with no modification or execution. The verb 'Get' is characteristic of Read operations.

POLICY

How to control verse_template_get

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_template_get:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "verse_template_get": {}
  }
}

verse_template_get is read-only, so it stays allowed — but 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.
