RECOMMENDED RULE

The rule that runs list_tools safely

list_tools Allowed

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

  }
}

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

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