WHAT IT DOES

What delete_rule does on Vultr MCP

AI agents call delete_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.

RISK

Why delete_rule is rated Critical

Delete operations are categorized as Destructive per the classification rules. The absence of description lowers confidence slightly (from 0.95 to 0.9), but the verb 'delete' combined with the context of a cloud infrastructure management platform indicates this tool irreversibly removes configuration data.

From the tool's definition Tool name 'delete_rule' directly indicates an irreversible deletion operation. No description provided, but the name unambiguously refers to removal of a rule (likely firewall, DNS, or security-related given the Vultr infrastructure context).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs delete_rule safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Vultr MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_rule, this is the rule to start with:

delete_rule Hidden

delete_rule is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
