Mailbox MCP

Mailbox MCP connects Claude to the email account you already have: Outlook and Microsoft 365, personal Outlook.com, Hotmail and Live, Gmail and Google Workspace, iCloud Mail, Yahoo Mail, Fastmail, Zoho, GMX, or any IMAP mailbox on your own domain. Nothing is migrated and no copy of your mail is kept. Email attachments, done properly. Claude sends real files without spelling them out in base64: a file already in your mailbox, a web link, or a file dropped on an upload link is fetched by the server as the message is built, up to 20 MB a message, and never passes through the chat. It reads inside them too: an invoice total, a spreadsheet, a scanned letter. Looking for a way to connect Claude to Outlook or Hotmail? This is it. It connects to the mailbox behind Outlook, so it works whether or not Outlook is installed. Ask what has come in and get the senders, subjects and first line of every message in one answer. Search across folders, read a message or a whole thread without marking anything as read, send, reply and forward as yourself or any alias, save a draft as a real threaded reply, and file or clear out mail the way your own mail client does. Routines put it on a schedule: a morning brief, replies drafted for the people waiting on you, the emails nobody has answered, or the bills that arrived. Add one to Claude as a scheduled task (a paid Claude plan) and its card shows when it last ran. Contacts and calendar come too: Outlook contacts, Google contacts or any CardDAV address book, and Microsoft 365, Google Calendar or CalDAV calendars. Find a person, see who is free, book and move meetings, and set your out-of-office. Every connection carries a permission level you choose: read only, draft and file, or send and delete. A shared mailbox can be worked by a team: claim a message, hand one on, hold a draft for approval. It can also tell you whether an email arrived.
