I had the impression that an alliance mothership fleet would at least receive station fleet and shield bonuses (and possibly recruit the station as a defender) if the mothership fleet is in orbit at a star with an alliance station and is subsequently attacked. This impression was reinforced by the small print note on the counterattack screen "The counter-attack will negate all space station bonuses if the target is in a protected system." My mothership fleet does not appear to receive any station bonus when remote attacked on SO Main, while parked in a system with my station. Bug or game mechanics change ?
