Capability Explorer

Capability Explorer is a tool to help explain how Moodle's capability system
works. Select a user, capability and context and you'll get a detailed
explanation of how that capability check is calculated by the system.

Minimum requirements

Moodle 2.7+. It should be possible to backport to any 2.x version by including
the treeview library in the module.

Note: This plugin does not current support sites that use MNet.


Install this plugin into the admin/tool folder, in a subfolder called
capexplorer, then visit the Site Administration > Notifications page to

You can then access the tool via:
