Its simple post the value to the controller and do what you want , in ajax request bind the value in data:{value_to_send:value} and get in controller

 function openPrompt()
{
var cancelled = true;

$.modal.prompt('Please enter a value:', function(value)
{

    $.ajax({
        type:"POST",
        data:{value_to_send:value}, 
        url:"/cakephp/controller/action/",
        success : function(data) {
           alert(data);// will alert "ok"

        },
        error : function() {
           alert("false");
        }
    });


    }, function()
   {

    });
    };
</script>

 public function action(){
    if( $this->request->is('ajax') ) {
     // echo $_POST['value_to_send'];
     echo   $value = $this->request->data('value_to_send');

     //or debug($this->request->data);
        echo "ok"
      die();
    }
   }
