Preheat an air fryer to 400 degrees F (200 degrees C).

Combine pork, water chestnuts, mushrooms, sesame oil, soy sauce, and Sriracha in a large skillet over medium-high heat. Cook and stir until pork is crumbly and no longer pink, about 6 minutes. Remove from heat and let sit until cool enough to handle, about 5 minutes.

Lay 8 dumpling wrappers on a clean work surface. Place a heaping teaspoonful of pork mixture in the middle of each wrapper. Pull both sides up like a taco and pinch the tops until sealed.
