How to Add the Claude Plugins Community Marketplace to Claude Code

Add the Claude plugins community marketplace to Claude Code by running claude plugin marketplace add anthropics/claude-plugins-community, then install any community plugin with claude plugin install <plugin-name>@claude-community.

The anthropics/claude-plugins-community repository hosts a read-only mirror of the community-curated plugin index for Claude plugins. Adding this marketplace exposes dozens of third-party plugins—from token swaps to design tools—directly within your Claude Code or Claude Cowork environment.

What Is the Claude Plugins Community Marketplace?

The community marketplace is defined by the .claude-plugin/marketplace.json file in the repository root. This JSON catalog lists every available community plugin with metadata including:

• name — the plugin identifier (e.g., 0x, 10x-shopping)
• description — human-readable summary
• source — URL to the plugin's source code
• homepage — link to documentation or landing page

Claude Code reads this file at registration time to populate its internal plugin index.

Register the Community Marketplace

Use the claude plugin marketplace add command to register the repository as a trusted source.

claude plugin marketplace add anthropics/claude-plugins-community

This command:

1. Validates the repository contains a valid .claude-plugin/marketplace.json
2. Adds anthropics/claude-plugins-community to your local marketplace registry
3. Makes all listed plugins available for installation under the claude-community namespace

Install a Community Plugin

Once registered, install any plugin by referencing its marketplace name with the @claude-community suffix.

claude plugin install <plugin-name>@claude-community

Example: Install the 0x Token Swap Plugin

claude plugin install 0x@claude-community

This downloads the plugin source defined in the marketplace JSON entry and registers its slash commands (e.g., /swap, /quote) for use in Claude Code sessions.

Example: Install the 10x Shopping Plugin

claude plugin install 10x-shopping@claude-community

Common Marketplace Commands

Command	Purpose
claude plugin marketplace add anthropics/claude-plugins-community	Add the Claude plugins community marketplace as a source
claude plugin marketplace list	Display all plugins available from registered marketplaces
claude plugin install <name>@claude-community	Install a specific community plugin
claude plugin marketplace remove anthropics/claude-plugins-community	Unregister the community marketplace

How Plugins Are Structured

Each marketplace entry references a plugin repository containing its own .claude-plugin/plugin.json manifest. Example paths from the source repository:

• tres-finance-plugin/.claude-plugin/plugin.json — financial data plugin
• quickdesign/.claude-plugin/plugin.json — design generation plugin

These manifests define the plugin's capabilities, entry points, and required permissions. Claude Code validates these files during installation.

Troubleshooting

"Plugin not found in marketplace"

Verify the plugin name matches an entry in the marketplace JSON. List available plugins with:

claude plugin marketplace list

"Marketplace already registered"

The marketplace can only be added once. To refresh the plugin list, run:

claude plugin marketplace remove anthropics/claude-plugins-community
claude plugin marketplace add anthropics/claude-plugins-community

Frequently Asked Questions

What plugins are available in the community marketplace?

The marketplace includes plugins for cryptocurrency trading (0x), shopping automation (10x-shopping), financial analysis (tres-finance), design generation (quickdesign), and more. Run claude plugin marketplace list after adding the source to see the complete, up-to-date catalog.

Can I use multiple marketplace sources simultaneously?

Yes. Claude Code supports multiple registered marketplaces. Each plugin installation command uses the @source suffix to distinguish which marketplace to query. The community plugins use @claude-community by convention.

Is the community marketplace officially maintained by Anthropic?

The repository is hosted under the anthropics organization but is explicitly documented as a read-only mirror of community-curated plugins. Anthropic does not guarantee support or security auditing for individual community plugins. Review each plugin's source URL before installation.

How do I contribute my own plugin to the marketplace?

Submit a pull request to anthropics/claude-plugins-community adding your plugin entry to .claude-plugin/marketplace.json. Your plugin repository must include a valid .claude-plugin/plugin.json manifest following the structure shown in existing entries like tres-finance-plugin and quickdesign.
