Multi Mail
Multi Mail puts your Gmail, Outlook.com, Hotmail, Microsoft 365, iCloud and Fastmail mailboxes in Cursor - several at once, one search across all of them. The agent finds what needs a reply, reads threads and attachments - PDF, Word, Excel, PowerPoint and scanned pages as text - drafts, replies, forwards and sends from the right address, and organises mail with labels, archive and trash; in Gmail and Outlook it also manages filters and the vacation responder. Each mailbox signs in with its own provider, or with an app password made on Apple's, Fastmail's or Google's own page, and you switch reading, drafts, sending, organising and settings on separately for every mailbox. Lumman keeps no copy of your mail: it is fetched from the provider when the agent asks and passed only to the client you approved, and mail that screens as a prompt attack is refused. The plugin is a remote MCP server, https://mail.lumman.co/mcp, with OAuth and dynamic client registration, plus four skills: triage, attachments, drafting (sends only after your yes) and label tidying. Microsoft lists Lumman Ltd, London, as a verified publisher.
