“You can now submit plugins to the Claude directory through a new developer portal, track them through review, and see usage analytics once they’re live.”

Anthropic’s announcement

A new route into the Claude directory

Anthropic opened its plugin submission portal on September 25, giving developers on paid Claude plans a way to send plugins to the company’s directory. The portal lets creators follow a submission through review and, if approved, choose when to publish it. The move creates a formal route from third-party development to discovery inside Claude, rather than leaving distribution solely to developers’ own channels.

Anthropic defines plugins as packages containing Model Context Protocol (MCP) connectors, Agent Skills, or both. Developers can submit a single remote MCP server or bundle MCP servers and skills in a GitHub-hosted repository. Claude Code plugins can also include language server protocol integrations, commands, hooks and agents.

Checks and review status come before publication

Each submission receives automated validation and a safety scan, Anthropic says. Developers can check their review status, see scan results and receive recommendations for changes through the portal. Approval does not trigger automatic publication: the developer decides when an accepted plugin goes live in Claude.

The announcement describes a review process, but does not say that automated scanning guarantees a plugin is safe. The distinction matters for extensions that connect Claude to outside services or bundle tools and skills. Anthropic’s stated process gives developers early feedback while keeping directory inclusion subject to approval.

Analytics track installs and discovery

After publication, developers will be able to view installs by Claude product surface and plugin version. The portal will also show how often a listing is viewed and which searches led users to it. Those measures give creators signals about adoption and discovery, though Anthropic’s announcement does not provide launch-day usage figures or detail how often the analytics update.

The portal supports plugins built around MCP, which Anthropic says now uses a stateless core in the specification it calls MCP 2.0. The company highlights MCP Apps, which bring interactive interfaces into chat, and Enterprise Managed Auth, which supports zero-touch OAuth for enterprise users. It says support for additional MCP features and extensions is planned.

Claude’s plugin directory is moving toward one discovery experience

Anthropic says a unified discovery experience across Claude and Claude Code will roll out over the coming weeks. Existing skills, connectors and plugins already listed in the directory do not need changes, and the company says the directory will continue to list skills and MCP connectors as separate building blocks. It also plans to let developers convert an existing connector listing into a plugin.

The launch ties distribution, review feedback and post-publication metrics to one submission path, but access to that path is limited to developers on paid Claude plans. For now, the concrete steps are straightforward: submit a remote MCP server or a GitHub-hosted bundle, address the portal’s review feedback, and publish after approval.
