In Calibre, you can click "Preferences" button on top bar, then click "Content Server" -> "Start Server" -> "Test Server", this will open a web browser, write down the URL in the browser (e.g.:
http://192.168.1.100:8080/ or
http://192.168.1.100:8080/opds);
then in Moon+ Reader "Online Library" tab, click "Add new catalog...", input this URL, restart the reader to access your own Calibre server.
