List device inventories with optional filtering
AI agents call list_device_inventory to retrieve information from Mender MCP Server 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 device inventory data without modifying, deleting, or executing any operations. It is a straightforward read operation that carries minimal risk when misused by an AI agent—the worst outcome is unauthorized information disclosure about device inventory, not data loss or system compromise.
