Anthropic opened a developer portal for submitting plugins to the Claude directory

Archive entry: this covers an event from September 25, 2026, and we published it on November 8, 2026. The details come from sources dated at the time and may have changed since.

On September 25, 2026, Anthropic opened a developer portal for submitting plugins to the Claude directory, as described in its post Build plugins for Claude. Through the portal, developers could submit a plugin, track it through review and see usage analytics once it was live.

What the portal covered

• Access: the submission portal was open to developers on paid plans.
• Two paths: a single remote Model Context Protocol (MCP) connector, or a plugin bundle hosted on GitHub.
• Claude Code plugins: in Claude Code, a plugin could include LSPs, commands, hooks and agents.
• Checks: submissions got automatic validation and a safety scan.
• For connector builders: the post pointed to the stateless core of MCP 2.0 and to the MCP Apps and Enterprise Managed Auth extensions.

What it meant for builders

MCP server authors and Claude Code plugin authors got an official path into the Claude directory, with review status and usage analytics. A remote MCP connector could go in on its own, and a bundle hosted on GitHub could carry Claude Code components.
