This is Anthropic, Read Aloud. Today: Build plugins for Claude.

2
00:00:06.879 --> 00:00:08.338
Build plugins for Claude.

3
00:00:08.788 --> 00:00:21.511
Submit plugins to the Claude directory through a new directory submission portal. Package M C P connectors and Agent Skills, track your plugin through review, and see how it's used and found once it's live.

00:00:27.371 --> 00:00:35.721
Every day, millions of people connect Claude to their apps, work tools, and data. Today, we're making it easier for developers to reach them.

6
00:00:36.171 --> 00:00:51.426
Plugins package M C P connectors, Agent Skills, or both, and are the main way to build third-party extensions for Claude. Build a plugin, submit it through the new directory submission portal, and once approved, it's listed in the Claude directory.

7
00:00:52.226 --> 00:00:55.796
Submit and track plugins in the directory submission portal.

8
00:00:56.246 --> 00:01:05.542
The directory submission portal is open to developers on paid Claude plans. There are two ways to submit and get your plugin published in the Claude directory:

9
00:01:05.992 --> 00:01:10.090
Single M C P connector: point to your remote M C P server.

10
00:01:10.330 --> 00:01:22.187
Plugin bundle: combine M C P servers and skills, host them on GitHub, and submit the repo. In Claude Code, plugins can also include LSPs, commands, hooks, and agents.

11
00:01:22.637 --> 00:01:27.496
Whichever path you choose, the portal will guide you from submission to launch. You can:

12
00:01:27.946 --> 00:01:35.054
Auto-validate your plugin. Each submission is checked and safety-scanned as soon as you submit, so you catch issues early.

13
00:01:35.294 --> 00:01:43.078
Review status and feedback. See where your plugin is in the review process, results from the safety scan, and recommended changes.

14
00:01:43.318 --> 00:01:48.252
Publish when you’re ready. Once approved, you decide when to publish your plugin in Claude.

16
00:01:56.378 --> 00:01:59.037
Monitor and improve your plugin once it's published.

17
00:01:59.487 --> 00:02:16.853
Once your plugin is live, usage analytics show installs by product surface and version, so you can prioritize fixes and features for your users. On the discovery side, you’ll see how often your listing is viewed and which searches lead people to it, so you can refine it to reach new users.

19
00:02:23.834 --> 00:02:28.727
Bring a rich experience to users with M C P 2.0 and its extensions.

20
00:02:29.177 --> 00:02:54.100
Claude supports the latest M C P spec, commonly referred to as M C P 2.0, which includes a stateless core. You can improve the experience of using your plugin with two M C P extensions: M C P Apps, for interactive U I inside chat, and Enterprise Managed Auth, for zero-touch OAuth for enterprise users. Support for more M C P features and extensions is coming soon.

21
00:02:54.900 --> 00:02:56.656
Start building plugins for Claude.

22
00:02:57.106 --> 00:03:18.669
Plugins are the main way for third-party developers to create extensions for Claude. Over the coming weeks, one discovery experience will roll out across Claude and Claude Code. Skills and M C P connectors stay as building blocks, and the Claude directory will continue to list them. In the future, developers will be able to turn their connector listing into a plugin.

23
00:03:18.789 --> 00:03:25.160
If you have an existing skill, connector, or plugin on the Claude directory, you do not need to make any changes.

24
00:03:25.610 --> 00:03:31.060
