Get the currently active Update Set for the session
AI agents call get_current_update_set to retrieve information from ServiceNow-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about the active Update Set in the current session. It performs no side effects, creates no data, modifies nothing, and triggers no external operations. It is a straightforward read/query operation. The blast radius of misuse is minimal—an AI agent retrieving this information cannot cause damage or unintended consequences in ServiceNow.
From the tool's definition Tool name 'get_current_update_set' and description 'Get the currently active Update Set for the session' indicate a query operation that retrieves configuration state without modification.
