AI agents call list_blocked_ips to retrieve information from cPanel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays existing blocked IP data without modifying, deleting, or executing any actions. It has no side effects on the system state. While it could reveal security configuration details, the impact of unauthorized access to this information is limited to information disclosure, making it a Read operation with low severity.
