The Media Resource Control Protocol (MRCP) is a network protocol based on the client/server model. MRCP allows client applications to control media service resources residing in servers. The first version of the protocol was published as an informational document, whereas its successor, MRCPv2, is currently a proposed standard.

UniMRCP is an open source cross-platform implementation of the MRCP client and server in the C/C++ language distributed under the terms of the Apache License 2.0. The implementation encapsulates SIP, RTSP, SDP, MRCPv2, RTP/RTCP stacks and provides integrators with an MRCP version consistent API.
