AI agents call pfsense_get_services_dns_resolver_access_list_network to retrieve information from Pfsense without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves DNS resolver access list information without modifying or deleting data. While it is a Read operation, severity is elevated to medium because the DNS resolver access list contains network security configuration details that could be sensitive if disclosed to an unauthorized agent, and the server has broad firewall control capabilities (677 tools).
From the tool's definition Tool name contains 'get_services_dns_resolver_access_list_network' and description specifies 'GET /api/v2/services/dns_resolver/access_list/network', indicating a read operation that retrieves DNS resolver access list network configurations.
