Groupsio

This server connects Claude to the Groups.io REST API, letting you query and manage mailing list data directly from your conversation. You get read access to subscriptions, messages, topics, archives, members, files, wiki pages, and events, plus write operations to update subscription settings or unsubscribe from groups. Useful when you're working with community data from Groups.io and want to search archives, pull member lists, or adjust your email preferences without leaving your workflow. Requires a Groups.io API key and runs via stdio transport with Node.js.
