Carré has not played for his country since 2023 and was previously ineligible under the Welsh Rugby Union (WRU) selection policy because he has 20 caps, five short of the number required for those playing for clubs outside of Wales.
But there are gaps, as demonstrated when Wales selected Jarrod Evans in the Six Nations earlier this year.
The Harlequins flyhalf also has under 25 caps but did not receive a reasonable offer to remain at former club Cardiff.
The same appears to apply to Carré, who left Cardiff last year to join Saracens for the second time.
Carré would have been available for the other home nations in 2026 because it will have been three years since he previously played for Wales.
Tandy says that situation did not contribute to his decision to recall the prop and has put his faith in Carré rather than Nicky Smith, who is named on the bench.
Carré is in the front row alongside Ospreys hooker Dewi Lake and Cardiff prop Assiratti.
Locks Beard and Jenkins return in the second row after missing the summer tour of Japan.
After helping the British and Irish Lions win the series against Australia, Wales captain Morgan comes into the back row alongside Cardiff flanker Alex Mann and Dragons number eight Aaron Wainwright.
Cracknell and Smith are joined on the bench by Freddie Thomas, Liam Belcher and Archie Griffin.
