Sickle's remote MCP server connects every mailbox you own to Claude, Claude Code, Cursor, Codex or any MCP client: Gmail and Outlook over OAuth, iCloud, Fastmail, Yahoo and any IMAP server, all at once. - **Twelve tools** to list, search, read, mark, move, trash, draft and send email across every account - **OAuth 2.1** with separate read, change and send scopes, revocable per client - **Approved sends**: sending is its own scope, and the send tool is marked destructive so clients ask before each email goes out; drafts and trash are reversible - **Nothing to install**: works from macOS, Windows or Linux Setup guides for each client and mailbox provider: https://sickle.app/resources Sickle is also a native Mac mail client for the same accounts. One subscription covers both, with the first 30 days free.
