In accordance with embodiments of the present disclosure, an information handling system may include a processor, a management controller communicatively coupled to the processor and configured to provide out-of-band management of the information handling system, and an interface for communicatively coupling the management controller to a second information handling system external to the information handling system for out-of-band management of the information handling system. The management controller may be further configured to serve as a proxy between one or more target management controllers of one or more other information handling systems and the second information handling system to facilitate out-of-band management of the one or more other information handling systems by the second information handling system while communicatively coupled to the interface.
