Cut the cucumbers into 1-inch pieces, discarding the ends. Using a small spoon or melon baller, scoop out the center of the cucumber. Drain upside down on paper towels.
Combine the cream cheese, chicken, peanut sauce, mayonnaise, tamari, garlic powder, and Sriracha (if using) in a food processor and blend, scraping down the sides of the bowl as needed, until very smooth. Pipe the mixture into the prepared cucumber cups.
