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

Contributing

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

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.

{
  "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": "<commit sha>"
  },
  "strict": false,
  "skills": [
    "./skill-a",
    "./skill-b",
    "./skill-c"
  ],
  "homepage": "https://github.com/example-org/sdk"
}

Each path in skills is relative to source.path and points at a directory containing a SKILL.md. Paths can reach deeper than a single level — for example, ["./libA/skill-1", "./libB/skill-2"] exposes a curated subset across multiple library subdirectories. Each skill is registered as <plugin-name>:<skill-name> in Claude Code.

For the underlying schema, see Strict mode in the marketplace documentation.
