Craddock was outstanding last season and weighed in with some crucial goals - including two against Tuesday night's opponents Stoke in the corresponding game at the Britannia Stadium.
He was restored to the starting line-up at the age of 35 after an injury-hit campaign for Saturday's 1-1 home draw with Fulham. But McCarthy has no doubts about Craddock being ready and in the right frame of mind for the finale.
The Wolves boss said: "Jody is the epitome of the player that we all want to have in our squads. He has been an absolute gem. To be fair, Christophe Berra and Richard Stearman have had a great spell and been terrific together.
"But I needed to change it and Craddock comes in at 35 and looks like a 25-year-old. He is terrific.
"It didn't surprise me at all because he comes in and trains and goes in the gym and works his socks off and has got a body fat of six per cent or something. He works at it all the time and is ready to go and plays in the reserves and does it properly. He is ready to go."
