The win ended a miserable season for the Cowboys, who finished 2010 with a 6-10 mark, and also possibly clinched the full-time head coaching position for interim head coach Jason Garrett.
After the game, Cowboys Owner/General Manager Jerry Jones said he will strictly follow NFL rules in regards to the interview process.
"I'm really interested in following the spirit of the NFL rules and that's what this is all about," Jones said. "I just want to move on so that we can have the coaching decisions out of the way and move on and do what we need to do."
Garrett went 5-3 after replacing Wade Phillips at midseason with Dallas owning a 1-7 record at the time.
McGee, who was making his first career start, led the Cowboys on a 54-yard scoring drive and helped them end a dismal season on a positive note.
After Philadelphia grabbed an early 7-0 lead in the second quarter, the Cowboys tied it when when DeMarcus Ware returned a fumble 17 yards for a touchdown.
David Akers kicked field goals of 43 and 22 yards in the fourth quarter before McGee led Dallas on the game-winning drive.
But the real story in a game in which the Eagles kept most of their starters on the bench was Garrett.
I would absolutely love to be this team's coach," Garrett said.
The Cowboys are expected to have a permanent head coach in place by the end of the week.
