The Black Country club, currently decimated by injury, would have enjoyed a much bigger margin of success than their 1-0 victory but for the heroics of Ben Foster who put in a sublime display at Molineux.
The England international goalkeeper was helpless, however, to stop Stephen Hunt's point-blank finish at the near post from Sylvan Ebanks-Blake's low cross on the stroke of half-time, a strike which put Wolves within one point of safety.
McCarthy believes the nature of the success says a lot for his battling outfit.
"I'm pleased, of course I am," said the Yorkshireman. "We've come away with a 1-0 victory but Wayne (Hennessey) has not made any saves of note to be fair. It was an all-round good performance.
"I'm delighted with our team's performance, we played well. People keep asking me about team spirit and morale and I keep saying `It's good'. I'm not sure people believe me but I think performances like that speak volumes for it."
