An apparatus includes a host and a baseboard. An out-of-band request is received via a host network interface of the host. The baseboard includes a management controller operating independently of the host and coupled to a management network interface separate from the host network interface. The out-of-band request is sent via an in-band communications channel from a proxy server of the host to a management agent running on the management controller microprocessor. Management data is formatted via the management agent. The management data is sent to the proxy server via the in-band communications channel. The management data describes hardware status that is obtained via the management controller in response to the out-of-band request. The management data is sent from the host network interface in response to the out-of-band request.
