delete_dns_record

THE RISK

Critical Risk

This action permanently deletes DNS records, which cannot be undone without manual intervention. DNS record deletion can break domain functionality, email routing, SSL certificates, and service availability. The blast radius affects all services relying on that DNS record.

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

HOW TO CONTROL DELETE_DNS_RECORD

PolicyLayer is an MCP gateway — it sits between your AI agents and Vercel 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.

Create a free account and register Vercel 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.
