You could read it from the request stream:

[HttpPost]
public ActionResult Foo()
{
    using (var reader = new StreamReader(Request.InputStream))
    {
        string xml = reader.ReadToEnd();
        // process the XML
        ...
    }
}

and to cleanup this action you could write a custom model binder for a XDocument:

public class XDocumentModeBinder : IModelBinder
{
    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        return XDocument.Load(controllerContext.HttpContext.Request.InputStream);
    }
}

which you would register in Application_Start:

ModelBinders.Binders.Add(typeof(XDocument), new XDocumentModeBinder());

and finally:

[HttpPost]
public ActionResult Foo(XDocument doc)
{
    // process the XML
    ...
}

which is obviously cleaner.
