AI agents call openvpn_get_connections to retrieve information from OPNSense 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 queries data about active OpenVPN connections with no side effects. It falls squarely into the Read category. While understanding active VPN connections could theoretically inform an attack, the tool itself performs only passive information retrieval.
