Claude Code Plugins Directory

A curated directory of high-quality plugins for Claude Code.

 ⚠️ Important: Make sure you trust a plugin before installing, updating, or using it. Anthropic does not control what MCP servers, files, or other software are included in plugins and cannot verify that they will work as intended or that they won't change. See each plugin's homepage for more information.

 Structure

- /plugins - Internal plugins developed and maintained by Anthropic
- /external_plugins - Third-party plugins from partners and the community

 Installation

Plugins can be installed directly from this marketplace via Claude Code's plugin system.

To install, run /plugin install {plugin-name}@claude-plugins-official

or browse for the plugin in /plugin  Discover

 Internal Plugins

Internal plugins are developed by Anthropic team members. See /plugins/example-plugin for a reference implementation.

 External Plugins

Third-party partners can submit plugins for inclusion in the marketplace. External plugins must meet quality and security standards for approval. To submit a new plugin, use the plugin directory submission form.

 Plugin Structure

Each plugin follows a standard structure:


plugin-name/
├── .claude-plugin/
│   └── plugin.json       Plugin metadata (required)
├── .mcp.json             MCP server configuration (optional)
├── commands/             Slash commands (optional)
├── agents/               Agent definitions (optional)
├── skills/               Skill definitions (optional)
└── README.md             Documentation


 Plugin names are immutable

The name field in a marketplace entry is an immutable slug. Once a plugin has been published, its name must not change — users have it installed under that slug, and renaming it breaks their install with a plugin-not-found error.

- To change how a plugin is labeled in the UI, set or update displayName instead.
- If a rename is genuinely unavoidable, add an entry to the top-level renames map in .claude-plugin/marketplace.json so existing installs auto-migrate:

json
"renames": {
  "old-name": "new-name"
}


The Claude Code plugin loader reads this map and transparently rewrites the old slug to the new one on the user's next sync.

 Skill-bundle plugins

When a plugin's source repository ships skills (SKILL.md files) without a .claude-plugin/plugin.json manifest, the marketplace entry can declare the skills directly using strict: false and an explicit skills array.

json
{
  "name": "example-bundle",
  "description": "Brief description of the bundled skills.",
  "author": { "name": "Author Name" },
  "category": "development",
  "source": {
    "source": "git-subdir",
    "url": "https://github.com/example-org/sdk.git",
    "path": "packages/agent-skills",
    "ref": "main",
    "sha": ""
  },
  "strict": false,
  "skills": [
    "./skill-a",
    "./skill-b",
    "./skill-c"
  ],
  "homepage": "https://github.com/example-org/sdk"
}


Each path in skills is relative to sou
