MCP for J connects an AI app (such as Claude) to your Joomla site, with tools for Joomla's own content, menus, modules, users and settings. An add-on gives that AI app tools for one more extension, for example VirtueMart, JCE or AcyMailing.
What you need
- MCP for J, installed and connected to your AI app. See the MCP for J manual.
- The extension the add-on is for, installed on the same site. We don't sell those: each comes from its own developer.
Each add-on is a small Joomla plugin. It adds its tools to MCP for J and does nothing on its own.
Install an add-on
- In your Joomla administrator, go to Components → MCP for J → Browse MCP Add-ons.
- Find the add-on and expand its card.
- Click Install.
The new tools are there the next time your AI app asks MCP for J for its tool list. In most AI apps that means starting a new chat or reconnecting.
You can also install an add-on's zip the normal way, at System → Install → Extensions.
Free and Pro add-ons
- Free add-ons install in one click. No account needed.
- Pro add-ons need the site linked to your cybersalt.com account first: on the MCP for J dashboard, enter your Purchase email under Link your Cybersalt Extensions account. See Pro extensions: linking your site.
Once the site is linked, the card for an add-on you own shows Active Membership Found — Install. An add-on you don't own yet shows Get it →, which opens its page on cybersalt.com. Pro add-ons are sold one at a time, or all together as MCP for J Pro — All Access.
Updates
When a new version of an add-on is out, its card in Browse MCP Add-ons shows Update to and the version number. Add-on updates also appear in Joomla's own update screen. See Updating an extension.
Who can use the tools
Add-on tools follow the same access settings as MCP for J's own tools. See Who can use it in the MCP for J manual.
Each add-on's page
Every add-on has a page under Extensions A-Z listing its tools, which ones are Free and which are Pro, the versions it's been tested with, and what it deliberately doesn't do.
