THE RISK

Critical Risk

Why delete_dns_record needs a policy

DNS records are critical infrastructure; deleting one cannot be undone without manual restoration. This is irreversible data destruction affecting domain resolution, making it the most severe category. High severity because misconfiguration could cause service outages or enable attackers to hijack domain routing. Confidence is high due to unambiguous 'delete' semantics in both name and description.

From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete a specific DNS record' — this irreversibly removes DNS configuration data.

POLICY

How to control delete_dns_record

PolicyLayer is an MCP gateway — it sits between your AI agents and Vultr MCP, 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 Vultr MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
