AI agents call delete_forwarding_rule 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.
The tool name explicitly contains 'delete', which is a destructive operation that removes a forwarding rule and cannot be undone. Despite the empty description limiting context, the semantic meaning of 'delete' combined with the infrastructure management context of the Vultr MCP server indicates this tool permanently removes a network configuration.
From the tool's definition Tool name contains 'delete_forwarding_rule' indicating irreversible deletion of network forwarding rules.
Documented attack patterns abuse exactly the kind of access delete_forwarding_rule 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_forwarding_rule:
{
"version": "1",
"default": "deny",
"hide": [
"delete_forwarding_rule"
]
}delete_forwarding_rule disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

delete_forwarding_rule. 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_forwarding_rule: 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_forwarding_rule 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_forwarding_rule 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_forwarding_rule. 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_forwarding_rule 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.
