AI agents call find_domain_users_laps_readers to retrieve information from BloodHound MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries Active Directory information about which domain users have permissions to read LAPS passwords—a reconnaissance/discovery operation with no side effects or data modification.
