WHAT IT DOES

What list_active_events does on ServiceNow MCP Server

AI agents call list_active_events to retrieve information from ServiceNow MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_active_events is rated Low

The tool retrieves or lists existing events for monitoring purposes. The verb 'list' and the monitoring context establish this as a read-only operation. While the data may be sensitive, the tool itself performs no side effects, creates no obligations, and cannot modify or delete data.

From the tool's definition Tool name is 'list_active_events' and description states 'Monitor critical infrastructure events' — both indicate a query/retrieval operation with no modification capability.
