AI agents call pfsense_get_services_dns_forwarder_apply_status 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 queries the current status of a DNS forwarder configuration without modifying, executing, or deleting anything. Despite the word 'apply' in the endpoint, the GET method indicates it is retrieving status information. It has minimal blast radius as it only returns state information about the DNS service.
From the tool's definition GET /api/v2/services/dns_forwarder/apply - HTTP GET method that retrieves the apply status of the DNS forwarder service
