csf_deny_ip · ItchWHM MCP: Risk & Policy

WHAT IT DOES

What csf_deny_ip does on ItchWHMMCP

AI agents invoke csf_deny_ip to trigger actions in ItchWHMMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why csf_deny_ip needs a policy

This tool triggers an external firewall operation (CSF - ConfigServer Security & Firewall) to block an IP address. This is an Execute-class action as it triggers an external operation with real-world effects on network access. The severity is high because blocking an IP can deny legitimate users or services access to the server, and misuse could cause significant disruption.

From the tool's definition Deny/block an IP address in CSF. Confirm with the user before using.
