The 24-year-old has swapped positions from back row to hooker over the past 12 months.
And, after an extended loan with English Championship side Bristol last term, McInally says the time is right to force his way into head coach Alan Solomons' side.
"I am ready to play for Edinburgh," he told the Edinburgh Evening News. "My goal is to get in the squad as quickly as possible.
"It is a big ask to get into the starting line-up ahead of Ross Ford and I have to be realistic that the bench will be a starting point.
"From there I hope to get a run and show what I have learned at Bristol."
Despite being a relative newcomer to the front row, McInally insists he has the qualities to become one of the best hookers around.
"I'd like to think I'd have gone on to play for Scotland in the back row but would I have gone on to be one of the best in the world? Probably not," he added.
"I've got the chance to maybe be one of the best hookers in the world, a chance to offer something a bit different."
