AI agents call delete_record to permanently remove resources in Vultr MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting DNS records is an irreversible action that immediately impacts service availability and domain routing. A mistaken deletion could redirect traffic, break email delivery, or take services offline.
From the tool's definition Tool name is 'delete_record' with description 'Delete a DNS record.' The verb 'Delete' and the irreversible nature of removing DNS records (which affects live traffic routing and cannot be undone without manual recreation) clearly classify this as Destructive.
Documented attack patterns abuse exactly the kind of access delete_record gives an agent:
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_record:
{
"version": "1",
"default": "deny",
"hide": [
"delete_record"
]
}delete_record disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a DNS record. It is categorised as a Destructive tool in the Vultr MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Vultr MCP server in PolicyLayer and add a rule for delete_record: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Vultr MCP. Nothing to install.
delete_record is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_record rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_record. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_record is provided by the Vultr MCP server (rsp2k/mcp-vultr). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Vultr MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
