Anthropic opens a submission portal for the Claude plugin directory
Anthropic announced on 25 September 2026 that the directory submission portal is open to developers on paid Claude plans. A submission can be a single MCP connector or a plugin bundle of MCP servers and skills hosted on GitHub, with automatic validation, review tracking and, after launch, installs by product surface and version. Anthropic said one discovery experience will roll out across Claude and Claude Code over the coming weeks.
Why it matters
Plugins become the main way to ship an extension for Claude, so an MCP server inside a listed plugin is reached from more places. The portal reports installs; whether the server inside answers well stays with its owner.
