Get asset details
AI agents call asset_get to retrieve information from ServiceNow 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 asset information from the ServiceNow CMDB without creating, modifying, or deleting any data. It is a read-only query operation that has no side effects on the system state. The blast radius of misuse is minimal—an agent could only access asset data it is already authorized to view.
