A plugin is a bundle of Claude Code extensions — skills, MCP servers, slash commands, hooks, or agents — packaged together as one installable unit. Plugins live inside marketplaces and can be installed with a single command.

What is the difference between a skill, a plugin, and a marketplace?

A skill is a single reusable instruction set. A plugin bundles one or more skills, MCP servers, or commands into an installable package. A marketplace is a GitHub repository that hosts and distributes multiple plugins under one registry.

How do I install a skill or plugin?

Copy the install command from any skill, plugin, or marketplace detail page and run it in your terminal. Most items install with a single command.

Yes, the directory is completely free and open. Browse and install any skills, MCP servers, plugins, or marketplaces at no cost.
