AI agents call pfsense_get_status_carp 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 performs a read-only query to retrieve the status of CARP failover configuration on the firewall. It retrieves data without modifying, deleting, or executing any operations. The GET HTTP method confirms it is a retrieval operation with no side effects.
