Anthropic Launches Developer Portal for Submitting Plugins to Claude Directory

Anthropic has launched a new developer portal allowing developers to submit plugins to the Claude directory. Plugins, which package MCP connectors and Agent Skills, are now the primary method for building third-party extensions for Claude. The portal is available to developers on paid Claude plans and guides users from submission through review to launch.

Submission and Review Process

Developers can submit plugins in two formats:

• Single MCP connector: Point to a remote MCP server.
• Plugin bundle: Combine MCP servers and skills, host them on GitHub, and submit the repository. In Claude Code, plugins can also include LSPs, commands, hooks, and agents.

The portal provides tools to streamline the process:

• Auto-validation: Submissions are automatically checked and safety-scanned upon submission.
• Review status: Developers can track their plugin's position in the review process, view safety scan results, and see recommended changes.
• Publish control: Once approved, developers decide when to publish their plugin.

Analytics and MCP 2.0 Support

After publication, developers gain access to usage analytics showing installs by product surface and version, as well as discovery metrics like listing views and search sources. This data helps prioritize fixes and refine listings.

Claude now supports the latest MCP 2.0 specification, which includes a stateless core. Two MCP extensions are available to enhance user experience:

• MCP Apps: Enables interactive UI inside chat.
• Enterprise Managed Auth: Provides zero-touch OAuth for enterprise users.

Future Roadmap

Over the coming weeks, a unified discovery experience will roll out across Claude and Claude Code. While Skills and MCP connectors remain as building blocks, developers will eventually be able to convert existing connector listings into plugins. Existing listings on the Claude directory require no immediate changes.
