RISK

Why vps_firewall_create_rule is rated Medium

This tool creates (writes) a new firewall rule, which is a reversible modification of infrastructure configuration. While it affects security posture and could be misused to open ports or weaken defenses, the action itself is not destructive or irreversible—rules can be deleted or modified. It does not execute arbitrary code, move funds, or permanently delete data.

From the tool's definition Tool name 'vps_firewall_create_rule' and description 'Add a rule to a firewall' indicate creation of a new firewall rule, which modifies firewall configuration.
