Description
I'm trying to create an MCP server using the servlet-based HttpServletStreamableServerTransportProvider. The application should be deployable as a WAR on an application server (e.g. Wiildfly).
I'm struggling to understand how I can get this to work. The class HttpServletStreamableServerTransportProvider, although annotated as @WebServlet, is not instantiable by the container and its only constructor is private such that it cannot be extended (although it is not final).
What is the indended way of getting an MCP servlet running in this usage scenario?

Research direction
Start with HttpServletStreamableServerTransportProvider, its @WebServlet annotation, and its private constructor. Trace how the SDK expects an MCP servlet to be created and deployed in a WAR on an application server such as WildFly. Done means the supported deployment path is implemented or clearly documented for this usage scenario.
