AI agents call delete_subdomain to permanently remove resources in cPanel MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a subdomain is a destructive operation that permanently removes DNS records, routing configurations, and associated settings. While not as critical as deleting entire databases, it irreversibly eliminates a domain resource and could impact email delivery, website accessibility, or application functionality tied to that subdomain.
From the tool's definition Tool name is 'delete_subdomain' with description 'Delete a subdomain'. The verb 'delete' indicates irreversible removal of a resource (a subdomain configuration), which cannot be undone without manual recreation.
Documented attack patterns abuse exactly the kind of access delete_subdomain gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and cPanel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_subdomain:
{
"version": "1",
"default": "deny",
"hide": [
"delete_subdomain"
]
}delete_subdomain 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 subdomain. It is categorised as a Destructive tool in the cPanel MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the cPanel MCP Server MCP server in PolicyLayer and add a rule for delete_subdomain: 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 cPanel MCP Server. Nothing to install.
delete_subdomain 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_subdomain 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_subdomain. 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_subdomain is provided by the cPanel MCP Server MCP server (0xhayd3n/cpanel-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from cPanel MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
