Get update set details with customer updates
AI agents call update_set_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.
The tool fetches details of an update set including its customer updates. This is a read-only retrieval operation with no side effects. Low severity as it only reads configuration metadata.
