Claude Code plugins: what they are and how to install them

Updated Oct 26, 2026 · Sources listed at the end

A Claude Code plugin is a directory that packages extensions (skills, subagents, hooks and MCP servers) so you can install them together. Type /plugin in a Claude Code session and install one from the Discover tab, which lists plugins from your marketplaces.¹

What is inside a plugin

The manifest, .claude-plugin/plugin.json, gives the plugin its name and optional version, description and metadata. Components can include:¹

• Skills: SKILL.md instructions Claude loads when relevant, and that you can also run as a command
• Agents: subagent definitions
• Hooks: commands that run at fixed points
• MCP servers: tool servers Claude Code connects to while the plugin is enabled

Plugins vs MCP servers

An MCP server adds tools. A plugin can bundle MCP servers together with instructions and automation, which makes it easier to share a whole workflow with a team.¹²
