  • Hostname:
  • IP:
  • Port: 6600
  • Password: none

How to use

ncmpc -h

Alternatively, there's a webinterface at

MQTT Control

The MPD can also be controlled via MQTT. Therefore, we have a service running that translates MQTT messages into MPD commands. It's currently running on the Docker machine (, and the code that's used can be found at
