The mailbox has to look untouched afterwards in Outlook or webmail, and that rule decides the implementation: reading never marks a message as read, a send files exactly one copy in Sent, a delete moves to Trash, a draft is saved where another client can edit it, a move keeps flags and the internal date, and folders resolve by their special-use flag instead of by name. It archives and reports spam by role rather than by folder name, so on Gmail archiving drops the inbox label. It reads attachments: a PDF, a Word file or a spreadsheet as text, a photo as a picture. After a send, check_bounces says whether an address failed for good or is being retried, and check_receipts whether it was opened, even when nothing came back. catch_up, waiting_on and owed_replies answer in one call each what came in, what nobody has answered and who is waiting on a reply. A diary connected separately adds calendar tools: reading and searching events, free/busy, booking and moving your own time, inviting, cancelling, answering or proposing another time, and the out-of-office reply. A CardDAV address book connected to an IMAP mailbox, also separately, lets find_contact read the book beside the mailbox's own history, and adds read_contact to open one card. No contact is stored on the server.","tools":{"check":["check_bounces","check_receipts","check_deliverability","check_upload"],"file":["move_email","archive_email","mark_junk","not_junk","delete_email","create_folder","rename_folder","delete_folder","create_upload_link"],"flag":["mark_read","mark_unread","flag_email","unflag_email"],"forward":["forward_email","draft_forward"],"read":["list_mailboxes","list_emails","read_email","read_attachment","read_thread","search_emails","select_emails","find_contact","catch_up","waiting_on","owed_replies"],"reply":["reply_email","draft_reply"],"send":["send_email","send_draft","draft_email","update_draft","list_identities"]},"toolsNote":"This list is the mail surface every connected mailbox gets. The calendar and contact tools are absent: each is registered only on a mailbox whose owner has connected a diary or an address book, and Outlook contacts on a Microsoft mailbox that reconnects, so listing them here would be a promise the server had not kept. find_contact is on every mailbox; a connected book improves it.","worksWith":["Any IMAP and SMTP mail host","Microsoft 365 and Exchange Online, over OAuth","Gmail and Google Workspace, with an app password","Microsoft 365 and Google calendars, over OAuth","Any CalDAV calendar server","Any CardDAV address book server"]}}}},"_meta":{"io.modelcontextprotocol.registry/official":{"status":"active","statusChangedAt":"2026-10-25T18:42:28.565927Z","publishedAt":"2026-10-25T18:42:28.565927Z","updatedAt":"2026-10-25T18:42:28.565927Z","isLatest":true}}}
