McCarthy said that he was happy to come away with a point as they could easily have lost the game.
"We messed it up in the second-half, didn't we," McCarthy told the club's official website.
"You have to give them credit though, they did to us what we did to them in the first-half and in the end it was a good point because we could have lost it.
"We didn't play well but we stuck at it and got something from a game that perhaps last season, we would have lost."
The Tractor Boys are 10th in the Championship.
