Ebanks-Blake was a prolific goalscorer in helping Wolves gain promotion back to the Premier League last season.
And he kept his nerve in drilling home a late equaliser from the penalty spot to cancel out Gabriel Agbonlahor's sixth goal of the campaign.
McCarthy said: "Sylvan has been desperate to get his first goal. We all believe he can play in the Premier League and score goals in it.
"Don't anyone under-estimate the taking of that penalty in that atmosphere. He has still got to score it and it was a fairly emphatic finish."
