Plugins

Install plugins that add skills, commands and agents to Multilo, choose who they're for, and keep them up to date.

A plugin is a bundle of things that change how Multilo’s agent works: skills, slash commands, agents, and sometimes hooks and MCP servers. Installing one adds them all at once. Each part is named after its plugin, as <plugin>:<name>, so you can tell where it came from.

Plugins are different from extensions, which add features to the app itself, such as new viewers or panels. To make and share a plugin, see Publishing skills. For the file formats, see Plugin files.

Find and install a plugin

Open Plugins
Go to Settings › Customize › Plugins and switch from Yours to Discover. Discover lists the plugins in every marketplace you’ve added, starting with Multilo’s own.
Install it
Click Install on the plugin. If a project is open, choose who it’s for (see below).
Confirm
Multilo asks: “Install <name> from <marketplace>? It is not reviewed by Multilo; its skills may include scripts the AI can run.” Click OK to install.

You can also install from a plugin’s page in the marketplace at www.multilo.com/marketplace/plugins: its Add to Multilo button opens Multilo and asks before installing. See Deep links.

Choose who it’s for

With a project open, Install for offers:

Choice	Who gets it
You, in every project	You, wherever you work. With no project open, this is the only choice.
Everyone in this project	Everyone who opens the project, for example co-authors sharing the folder
Just you, in this project	Only you, and only in this project

A plugin your organization installs for you is marked set by your organization.

Install from a folder or a .zip

To install a plugin you have on your computer, click Add and choose Install from folder or Install from .zip. It’s listed as From a file.

Manage your plugins

Yours lists your installed plugins. Each one shows where it came from, its version, who it’s installed for, what it contains, and whether it’s turned off. Each plugin has these buttons:

Button	What it does
Turn off / Turn on	Stops or starts its skills, commands and agents without removing it.
Update	Installs a newer version now, if there is one.
Uninstall	Removes it. Multilo asks first: “Uninstall <name>? Its skills, commands and agents go with it.”

If a plugin couldn’t load, it’s listed under Errors with the reason.

Approve a plugin’s hooks and MCP servers

A plugin’s skills, commands and agents work as soon as it’s installed. Its hooks and MCP servers don’t: “Its hooks and MCP servers run only after you approve them.” Approve each one in the Hooks and Connectors tabs of Settings › Customize. See Hooks and MCP.

Marketplaces

A marketplace is a list of plugins that someone maintains. Multilo adds its own for everyone and keeps its plugins up to date.

Add a marketplace: click Add › Add marketplace, then enter a GitHub repository as owner/repo, or a folder on your computer.

Add only marketplaces you trust

“Marketplaces you add are not reviewed by Multilo. Add only ones you trust.” A plugin’s skills can include scripts the AI runs.

In Discover, each marketplace has two links:

Auto-update on / Auto-update off installs new versions of its plugins when Multilo starts. It’s on for Multilo’s marketplace and off for marketplaces you add.
Remove removes the marketplace and uninstalls the plugins you installed from it.

A marketplace your organization adds can’t be removed, and is marked set by your organization.

Troubleshoot

Problem	What to do
“This marketplace has no plugins yet.”	The marketplace lists no plugins, or its list couldn’t be read. Check with whoever maintains it.
A plugin is listed under Errors	Read the reason shown. Often a file in the plugin is missing or invalid; update or reinstall it, or tell its publisher.
A plugin doesn’t load and names your organization	Your organization doesn’t allow its marketplace. Ask your administrator.
“That didn’t work.”	The install, update or removal failed. Check your internet connection and try again.
An update doesn’t arrive	Click Update on the plugin, or turn on auto-update for its marketplace. If there’s still nothing new, the publisher hasn’t released a new version.
A plugin’s hook or MCP server does nothing	It hasn’t been approved yet. Approve it in the Hooks or Connectors tab.
