Welche Funktion hat eigentlich Agent XPs bei SQL

The Agent XPs are extended stored procedures used by the SQL Server Agent that provide privileged actions that run externally to the DBMS under the security context of the SQL Server Agent service account. If these procedures are available from a database session, an exploit to the SQL Server instance could result in a compromise of the host system and external SQL Server resources. Access to these procedures should be disabled unless use of SQL Server Agent is required and authorized.
