McCarthy, 23, returned to Cantilever Park for a second spell at the club from Runcorn Linnets having previously played on loan from Telford two years ago.
He came off the bench in Saturday's 4-0 win over North Ferriby United, a game in which Kirby scored the third goal.
Kirby, 24, only had his loan deal from Stockport County extended last week, but he has now been recalled by the National League North side.
The Yellows are without a game this weekend and are next in action in the EVO-STIK League Premier Division on Saturday December 22 against Buxton.
