# Plugins

Plugins give your agent new tools and capabilities, ready to use out of the box.

## What are plugins?

A plugin is a set of:

- **Rules**: persistent AI guidance and coding standards
- **Skills**: specialized agent capabilities for complex tasks
- **Commands**: agent-executable command files
- **MCP servers**: Model Context Protocol integrations
- **Hooks**: automation scripts triggered by events

Plugins work across Cursor desktop, web, and CLI. Browse official plugins in the [Cursor Marketplace](/marketplace). For community plugins and MCP servers, browse [cursor.directory](https://cursor.directory). You can also [build your own](https://cursor.com/docs/reference/plugins.md).

## How do I install a plugin?

Browse the [Cursor Marketplace](/marketplace) or search by keyword in the marketplace panel inside Cursor. Plugins can be scoped to a project or installed at the user level.

Every plugin is a Git repository. All plugins are open source and [manually reviewed](https://cursor.com/help/security-and-privacy/marketplace-security.md) before listing.

## Are plugins reviewed for security?

Yes. Every plugin is open source and manually reviewed before it appears in the marketplace. Each update is re-reviewed before publishing.
