Get HR lifecycle events for an employee (promotions, transfers, leaves)
AI agents call get_hr_lifecycle_events 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 is a straightforward data retrieval tool that queries existing HR records without side effects. It does not create, modify, delete, or execute operations. The blast radius of misuse is minimal—an attacker could potentially access employee records they shouldn't see, but this is a confidentiality concern rather than a capability risk that would trigger higher categories. Classified as Read with low severity.
From the tool's definition Tool description states 'Get HR lifecycle events' - a retrieval operation with no modification, creation, or deletion of data. Returns historical employment events (promotions, transfers, leaves) for informational purposes.
