In a food processor, pulse graham crackers in batches until finely ground. Add butter and pulse until crumbs bind together. Press 2 tablespoons crumb mixture into each of 6 (4-ounce) mason jars. Reserve remaining crumb mixture.
Wipe out food processor and add cream cheese, pumpkin, Monk Fruit In The Raw®, pumpkin spice, and vanilla. Process until completely smooth. Transfer mixture to a large resealable plastic bag and cut ½” off one corner. Pipe mixture into jars. Cover and chill completely. When ready to serve, sprinkle each cheesecake with reserved graham cracker mixture and pecans.
