Alternatives to Inbox Zero

Inbox Zero is a MCP server by elie222: Search Gmail and Outlook, save drafts, manage email rules, and view email stats. If it doesn't fit your setup, these 12 MCP servers cover similar ground. They are ordered by how closely they match Inbox Zero and by our rank, which weighs adoption, freshness and documentation; money never changes the order. Email MCP leads the list (supports Codex and Claude Desktop; runs locally). 3 of them are published by the company behind the product. 6 offer a remote endpoint, so there is nothing to install locally.
