McCarthy's men are six points clear of second-placed Birmingham and seven ahead of Sheffield United with just three games to play.
"It's very close now," Ebanks-Blake told the club's official website. "A lot of people are very happy with the position we're in and it's a great position to be in but we've got to finish the job.
"What a position to be in with three games to go when we only need to match up other results, whether it's win, lose or draw.
"You can't ask for any more than that, but we'll be trying to get the job done in style by winning our last three games."
The striker has been missing of late because of a calf strain and then a hamstring injury, but could be in line for a return to side against QPR after returning to training this week.
Rangers, meanwhile, will be looking to close out a rollercoaster season - which has seen the departure of managers Iain Dowie and Paulo Sousa - on a high.
Caretaker boss Gareth Ainsworth knows victory at Molineux will be a tough ask, telling the club's website: "A couple of teams have been up there and got decent results this season, but I'm under no illusions and we're expecting a very difficult game.
"They're top of the league for many reasons. They're a strong, powerful, excellent footballing side, who have goals all over the park, but we'll go up there and give our all to get a victory."
