I am using Tulip 3.1.2 and found that plugin manager is showing only installed plugins. Later found that URL http://tulip.labri.fr/pluginsServer/server.php (which is using as plugin server) is no more available.
We are really sorry but Tulip 3.1.2, which is about 4 years old,
is no longer supported.
If you need a fresh Tulip 3 version use Tulip 3.8.0 instead.
It is available for download at https://sourceforge.net/projects/auber/files/tulip/tulip-3.8.0/
Hope this helps
