SPCS: Simple PHP Content Server for Calibre

SPCS, or Simple PHP Content Server, is a PHP based content server that reads directly from the Calibre metadata.db file.

Features include:

  • Support in most major desktop, mobile and Kindle browsers
  • Built-in multi-user login functionality allowing for direct book download to Kindle and Android devices
  • “Send-to” functionality to support Whispersync with Amazon’s Personal Documents feature
  • No need to have Calibre running
  • Sortable results
  • Cover display


Grab the latest zip from the builds directory.


Installation is simple and straightforward:

  • Extract the archive to any folder on a system running PHP. Ensure Pear Mail tools are installed.
  • Edit /include/config.php to your liking.
  • Ensure the metadata.db file AND the folder it resides in is writable by the Apache/IIS user.
  • Visit https:////setup.php to install. This will create a new table (spcs) in your Calibre database with a user “admin” and password “password”.
  • Visit https:/// and login as “admin” with password “password”.
  • Go to settings to change password and Kindle email address.
  • Other users can be set up by using a Sqlite editor like Sqlite Database Browser. Just add a row with a username and blank password, and change it on first login.

NOTE: Downloading with “Basic Authentication” causes problems, thus the included login interface. However, we STRONGLY recommend you force HTTPS/SSL to secure your passwords. Also, this application has NOT undergone strict security testing.
