Why edit_dns_record needs a policy

This tool modifies DNS records, which are reversible operations (Write rather than Destructive). However, the severity is high because DNS misconfigurations can disrupt email delivery, break domain resolution, compromise security records, and cause widespread service outages. An AI agent could inadvertently redirect traffic, disable DKIM/SPF authentication, or break domain functionality with incorrect edits.

From the tool's definition Tool name is 'edit_dns_record' and description states 'Edit an existing DNS zone record'. The verb 'edit' indicates modification of existing data (Write category).

POLICY

How to control edit_dns_record

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

policy.json

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

edit_dns_record 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
