获取当前设备的 VPN 信息
AI agents call getVpnInfo to retrieve information from Current operating environment without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about the device's VPN configuration. It follows the pattern of sibling tools (getAppSchemas, getBatteryInfo, getCpuInfo, etc.) which are all informational queries about system state. The function only reads and returns data without modifying, executing, deleting, or creating anything.
From the tool's definition Tool name 'getVpnInfo' and description '获取当前设备的 VPN 信息' (Get current device VPN information) indicate a query/retrieval operation with no side effects.
