No you don't need any development tool on the server. You don't even need Windows since a silverlight application can be hosted by any web server.

Check that your .xap file has been made accessible on your web server and that the .xap/.xaml MIME types have been set.
This documentation about deploying a silverlight application : http://msdn.microsoft.com/en-us/library/ff921170(PandP.20).aspx should help.
