Why get_ntp_peers needs a policy

This tool queries the status of NTP peers on network devices. It retrieves configuration or state data from devices without creating, modifying, deleting, or executing any operations. The verb 'get' and lack of any modification language confirm read-only semantics. No financial, destructive, or executable side effects are indicated.

From the tool's definition Tool name 'get_ntp_peers' and description 'Get the status of NTP (Network Time Protocol) peers' indicate retrieval of status information without modification.

POLICY

How to control get_ntp_peers

PolicyLayer is an MCP gateway — it sits between your AI agents and Nornir MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_ntp_peers:

policy.json

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

get_ntp_peers 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 Nornir MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
