- Models affected: Claude

Anthropic opened a new developer portal allowing developers on paid Claude plans to submit plugins to the Claude directory. Plugins package MCP connectors, Agent Skills, or both, and can be submitted as single MCP connectors or plugin bundles combining MCP servers and skills hosted on GitHub. Once approved, plugins are listed in the Claude directory, and developers gain access to usage analytics tracking installs by product surface and version, as well as discovery metrics.

## Evidence

Verbatim from https://claude.com/blog/build-plugins-for-claude:

> Plugins package MCP 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.
