Leroy Lita smashed in his fifth Wednesday goal early in the second period to cancel out Jay Tabb's fortuitous 12th-minute opener at Hillsborough as Jones' men moved four points clear of the bottom three.
McCarthy agreed the game was an even affair and admitted he would have taken a point prior to kick-off.
"There isn't a bad away point," he said.
"We played well enough to be in front by more in the first half but then Dave (Jones) will argue that they've had the better of the second.
"I think he said they had a goal disallowed - no they didn't, there was one that went in the net that was offside; it's not a goal. We had one that we thought was over the line and, if it isn't, it's not a goal.
"So, probably honours even in terms of playing and result and we shouldn't have even bothered; I'd have taken a point before we started. Instead of kicking lumps out of each other, we could've just settled it."
On the subject of Ipswich retaining their Championship place, McCarthy added: "There must be some equation somewhere, if somebody can come up with one so I can enjoy a glass of something tonight and not think 'if this happens and that happens' - it's just been bonkers.
"But there must be because Peterborough have got to play these, and Barnsley have got Huddersfield; they're all playing each other. Somebody come up with the equation and print it so I can enjoy my Sunday."
