Summer arrivals Cammy Bell, Steven Smith, Richard Foster, Nicky Clark, Jon Daly and Nicky Law are among a 23-man pool for friendlies against Brora Rangers on Sunday and Elgin on Wednesday.
French-Tunisian defender Bilel Mohsni, who left Southend at the end of last season, will also join the party as he bids to win a contract.
McCoist, who will take his squad to Germany after a friendly at Bristol City on July 13, told his club's official website: "We are lucky in that we have the best facility in the country in the form of Murray Park. It's fantastic and we are blessed to have it.
"At the same time, it can be extremely beneficial to get the players away from their own environment where they are all together.
"They will get a chance to get to know each other away from the football park as well when we're in Brora and that's a big thing.
"We've got a few new faces in the group who have still to get to know each other and their new team-mates."
Another of McCoist's seven summer signings, Honduras midfielder Arnold Peralta, has still to arrive in Scotland following his international exertions.
Dean Shiels, Chris Hegarty and Barrie McKay will stay behind at Murray Park to continue their rehabilitation from injury.
