Is MPC Still Part Of The System

Just wondering… Is MPD and MPC still part of the system? I am running commands in mpc, and I am able to add a url to the queue and start it playing, but nothing is reflected in the front end (web UI): nothing in the queue appears, no indication of playback.

Can someone point me in the right direction to simply start playing a web url (mp3) from the command line or programmatically?
