Is there a project that auto-generates JavaScript proxy code to call ASP.NET MVC action methods?

Question

Is there c# code that takes an existing controller, analyse its public Action methods and generate a JavaScript proxy class so that it can be easily called by other Javascript code? I already know we can use jquery to do a $.post and $.get to call our ajax services but I believe the process can be simplified by not having to specify the relative url of the AJAX web service URL and a parameter name for each parameter input.

For example, let's say we have the following C# controller:

public class CustomerController : Controller
    {

        public JsonResult Create(string name, string address)
        {
            return new JsonResult {Data = 11111};
        }

        public JsonResult Update(int id, string name, string address)
        {
            return new JsonResult {Data = true};
        }
    }

I would like to call the controller's AJAX action methods by using the following fashion.

Proxy.Customer.Create("Scott Gu", "Somewhere in Redmond").done(function(id) {
      /* id is an int and not an string */
      Proxy.Customer.Update(id, "Scott Gu", "Somewhere in Seattle");
});

Does a project exist that allow me to do this?

Update

it turns out there's no project that does what I asked for. Something that could be of use, besides SignalR, is Phil Haack's Controller Inspector project. It can inspect any given controller and reveal what action method it has, the parameters it accepts, their types, etc.

The following link contains the getter method for retrieving a details about a given controller. https://github.com/Haacked/CodeHaacks/blob/master/src/MvcHaack.ControllerInspector/ControllerDetailer.cs

Update 2

Doh. Phil Haack already developed a JavaScript proxy. Tutorial can be found here.

I know, it's an old question, but I just found a project which seems to match your requirements:
