Anthropic publishes three general-purpose plugin marketplaces for Claude Code: official, community, and demo. Each is a catalog of plugins in its own GitHub repository. When you install a plugin from one of them in a Claude Code session, you type the marketplace’s name after @, as in /plugin install commit-commands@claude-plugins-official. Use this page to distinguish the three marketplaces and to find where to check whether the official one holds a given plugin.
These cases are covered on other pages:

​
Anthropic’s marketplaces

A marketplace is a catalog of plugins that a repository defines in its .claude-plugin/marketplace.json file. The official, community, and demo marketplaces each come from their own GitHub repository. Anthropic also publishes topic-specific marketplaces, such as anthropics/skills and anthropics/knowledge-work-plugins, which you add in a Claude Code session with /plugin marketplace add <owner>/<repo>. This table gives each marketplace’s repository and marketplace name, which is what you type after @ when you install a plugin from that marketplace. The community marketplace’s name is claude-community, not its repository name. If you wrote a plugin and want other people to install it, see Publish a plugin, which covers your own marketplace and submitting to the community marketplace.

​
The demo marketplace in anthropics/claude-code

If a tutorial or an older set of instructions tells you to run /plugin marketplace add anthropics/claude-code, that adds the demo marketplace, named claude-code-plugins. It isn’t the official marketplace, which Claude Code already added for you. Most of the demo marketplace’s plugins are also in the official marketplace under the same names. For example, code-review, feature-dev, commit-commands, and security-guidance are in both. Install those from claude-plugins-official so you don’t have two copies installed.

​
Find plugins in the official marketplace

The official marketplace, claude-plugins-official, is the one Claude Code adds for you. Most of what it lists comes from partners and other authors rather than from Anthropic: tool vendors publish plugins that connect Claude Code to their services, and Anthropic maintains a smaller set of its own, such as commit-commands, code-review, feature-dev, and the language server plugins. The catalog changes often, so this page doesn’t list it. To see what’s in it, use the Discover tab of /plugin in a Claude Code session, which you can search, or browse Claude Marketplace on the web.

​
Browse and install from Anthropic’s marketplaces

You can search Anthropic’s marketplaces for a plugin in Claude Code, on the web, or on GitHub:
  • In Claude Code, by browsing: run /plugin in an interactive session. Its Discover tab lists the plugins from the marketplaces you’ve added.
  • In Claude Code, by name: run /plugin install <name> in a session, which looks the name up in the marketplaces you’ve added. If the plugin is in one of them, its details open in the /plugin panel, and nothing installs until you choose an installation scope and confirm there. If it isn’t, you see Plugin "<name>" not found in any marketplace.
  • On the web: search the full catalog on Claude Marketplace, which shows install counts and marks some plugins Anthropic verified.
  • On GitHub: open .claude-plugin/marketplace.json in the marketplace’s repository, such as anthropics/claude-plugins-official. That file is the catalog itself.
To install from the desktop app or from a script, or to see what a cloud session loads, see Install plugins.

​
Add the community or demo marketplace

The community and demo marketplaces aren’t registered until you add them in a Claude Code session:
  • Community: run /plugin marketplace add anthropics/claude-plugins-community, then install with the @claude-community suffix.
  • Demo: run /plugin marketplace add anthropics/claude-code, then install with the @claude-code-plugins suffix.
If claude-plugins-official isn’t on the Marketplaces tab of /plugin, add it the same way with /plugin marketplace add anthropics/claude-plugins-official. For not found errors and marketplaces that won’t add, see Troubleshoot plugins.

​
Third-party marketplaces

Many popular plugins aren’t in any Anthropic marketplace. They’re in their authors’ own marketplaces, usually a GitHub repository with a .claude-plugin/marketplace.json at its root. Anthropic doesn’t review third-party marketplaces, so read Plugin security and trust before you add one. To use a third-party marketplace, add its repository in a Claude Code session with /plugin marketplace add <owner>/<repo>, then install with /plugin install <plugin>@<marketplace-name>. The marketplace name is the name field of that marketplace.json, and Claude Code prints it once it has added the marketplace. For other ways to add a marketplace, see Add a marketplace.
