RECOMMENDED RULE

The rule that runs get_variation safely

get_variation Allowed

get_variation is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

    "get_variation": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Webcake Storefront, apply this rule, and every get_variation call is checked against it from then on.
