The article shows the present construction state of the MCORD detector (MPD Cosmic Ray Detector) demonstrator and early designstatus of the full MCORD detector based on thelong and thin plastic scintillators with silicon photomultiplier photodetectors (SiPM) for the photon readout. Additionally we describethe analog front-end and digital electronic system based on MicroTCA crate. The Multi-Purpose Detector (MPD) is a part of Nuclotron-based Ion Collider fAcility (NICA) located in Dubna, Russia. The MPD needs an additional trigger system for better muons recognition and for rejection of cosmic ray muons. The NICA-PL consortium comprised of several Polish scientific institutions has been formed to determine goals and basic assumptions for MCORD detector.
