We were operating with MEL 27-XX; Pitch Control Disconnect Advisory Message; which requires other MELs; including MEL 22-XX Autopilot System. Approach Control turned us onto final for a visual approach to Runway XX and instructed us to contact Tower. After tuning the #1 com radio to the Tower frequency; we began configuring the aircraft for landing when we received the autopilot warning along with the AP (Autopilot) Fail and Pitch Control Disconnect EICAS messages. This was a bit distracting because the autopilot was not in use nor had it been used the entire flight due to [the] MEL. After determining all systems were okay to continue; we then started receiving the EGPWS glideslope warning. I determined this was due to ATC having the ILS for Runway XY turned on. The FO (First Officer) had established a normal visual approach angle so I told him to continue. I then reset the frequencies in both nav radios to silence the errant warnings. After landing; the Tower issued taxi instructions and said that next time we should contact Tower for a landing clearance.[The cause was] multiple distractions. Don't let minor distractions dominate the flight deck.
E175 Pilot not Flying reported that distractions from malfunctioning systems in the cockpit led to communications issues; resulting in a landing without clearance.
