Having conceded two in the last 10 minutes to lose 2-1 to Birmingham at the weekend, McCarthy was pleased his players had shown no ill-effects.
"It is a good win over Spurs but that still rankles," he said of the Blues defeat.
"Today we were terrific. It wasn't easy, we've had to play well and it was damned hard work and we deserved it.
"It was good that we were 1-0 ahead and didn't allow Sunday to affect that.
"I have never once doubted the attitude of my players - I never have.
"I keep getting asked about their character, about bouncing back and being able to get off the canvas and all those other cliches and it has never been in doubt about them."
Jones' goal came after a sustained spell of possession and McCarthy admitted, for all Wolves' reputation as a hard-working, gritty side, he enjoyed it.
"I've heard 17 passes and 19 passes but I've not actually counted them myself," he added.
"It was a fabulous goal, it really was. Jonesy has been terrific and gives us real quality.
"His technical ability is Premier League class and it has been a good role for him playing just behind Kevin Doyle, it suits him."
Goals have been a problem for Spurs in recent weeks, with just three scored in the league since the turn of the year but Harry Redknapp felt things would have turned out differently had Niko Kranjcar put away a one-on-one chance with goalkeeper Marcus Hahnemann before Wolves had opened the scoring.
"It was a game we obviously thought we could win but we didn't play very well," he said.
"We had an awful lot of the ball but didn't create a lot - even in the first half when we got in some good positions.
"When Niko went through, if he had scored it would have been a different game.
"In the second half they got bodies behind the ball and defended their lead well."
With Liverpool losing on Wednesday night Tottenham could have regained fourth spot but Redknapp was left to rue a second 1-0 defeat to Wolves this season.
"We've dropped six points against Wolves, which looks like being very costly, but what can you do?," he added.
