AI agents call get_ipsec_tunnels to retrieve information from AF_MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves the status of IPSec VPN tunnels. It performs a read-only operation that returns information about existing tunnel states without creating, modifying, deleting, or executing any changes to system configuration or network operations.
