What "all" means here
This list covers every first-party item found in Anthropic's own catalogs, plus the most notable partner and community ones. Anthropic's marketplaces hold thousands of items, so no single page can list them all. "Partner" means a company built the add-on to connect Claude to its own product or service. "Community" means a standalone add-on from an independent developer or small company. Counts change daily.

They power Claude's file features in claude.ai and the Claude API. Anthropic publishes them as source-available, not open source, per the skills repo. File creation works on every plan, including Free, per the help center.

How to add one
In claude.ai or the desktop app, open Customize from the sidebar. Choose Connectors, Skills or Plugins, then open Discover. Select an item and add it, then sign in to any service it needs. In Claude Code, run /plugin to browse marketplaces, or install a plugin by name.
- Connectors: Customize > Connectors > Discover, then Connect to Claude. Turn it on per chat from the + menu.
- Skills: on Pro, Max, Team or Enterprise, turn on Code execution and file creation in Settings > Capabilities, then use Customize > Skills.
- Plugins: Customize > Plugins > Discover, then Add. Plugins you add here sync to Claude Code.
- Anthropic's other marketplaces: Customize > Plugins > Add > Add marketplace > Browse Anthropic sources, then add Financial Services, Legal or Life Sciences. Only Knowledge Work is added by default.
- Claude Code: run
/plugin install name@claude-plugins-official. For community plugins, first run/plugin marketplace add anthropics/claude-plugins-community, then install with@claude-community.
On Team and Enterprise plans, an Owner decides which connectors and plugins members can use. For the full walkthrough, see Claude skills, plugins and connectors explained.
Stay safe with third-party add-ons
Skills and plugins can run code, and connectors can read and change your data. Anthropic reviews plugins in its directory with automated checks, a security scan and a human review of new listings. It does not review plugins added from a marketplace link or uploaded by you. Third-party marketplaces get no Anthropic review at all.
- Prefer items from the directory or from the company behind the product.
- Read a skill's SKILL.md and files before you turn it on.
- Treat the Verified label as a quality check, not a security audit, per Anthropic's verification page.
- Check the permissions a connector asks for at sign-in, and keep tool approvals on.
- Remember that local servers and hooks run commands on your computer.
