Why edit_dns_record_by_name_type needs a policy

This tool modifies DNS records, which is a Write operation (creates/modifies data reversibly). It affects all matching records in bulk, giving it high blast radius if misused by an agent (could redirect traffic, break services, enable phishing), but the action is reversible via further edits, so it is not Destructive. The Write category is appropriate.

From the tool's definition Tool name contains 'edit'; description states it 'Edits all DNS records matching a domain, subdomain (optional), and type.' The action is reversible modification of DNS configuration.

POLICY

How to control edit_dns_record_by_name_type

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

policy.json

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

edit_dns_record_by_name_type 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.
