Technologies are described herein for executing an out-of-band agent in an in-band process of a host system. An out-of-band connection is created between a service processor located on a host computer and a remote management device. The service processor receives an agent program from the remote management device over the out-of-band connection and stores the agent program in a storage area. The agent program is made available to an in-band process of the host system operating on the host computer through a standard storage device interface. The agent program is then executed out-of-band by the service processor or in-band by the process of the host system.
