THE RISK

Why delete_dns_record needs a policy

This tool permanently deletes DNS records, which cannot be undone and has a broad blast radius: an AI agent misusing it could disrupt domain routing, email delivery, SSL certificate validation, and overall service availability. The action is irreversible and impacts production infrastructure. Destructive is the most appropriate category, with high severity due to potential service outage impact.

From the tool's definition Tool name is 'delete_dns_record' and description states it 'Removes an existing DNS record from a domain name'. The verb 'delete' combined with 'removes' indicates irreversible deletion of DNS configuration data.

POLICY

How to control delete_dns_record

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_dns_record"
  ]
}

delete_dns_record disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
