BumbleBox MCP server

• archive_emailwrite actionFree

  Moves one inbox email to its mailbox's archive folder, on the mail server too. Undone by restore_to_inbox. Nothing is deleted.

• create_campaign_draftwrite actionFree

  Writes one draft inside an existing campaign, to one recipient (added to the campaign list if new), from the campaign's sender. Nothing is sent: the draft waits for the user to validate the campaign send in BumbleBox.

• draft_replyFree

  Saves the text as the reply draft of a received email, from the mailbox that received it. Nothing is sent: the draft waits in BumbleBox (Pilotage › prepared replies) until the user reviews it and clicks Send. Saving again replaces the previous draft of the same email.

• get_emailwrite actionFree

  One email in full: sender, recipients, date, subject, plain-text body, attachment names, folder and BumbleBox classification.

• list_calendar_eventsFree

  Events of the connected Google calendars between two dates (default: the next 7 days, at most 62 days).

• list_campaign_draftsFree

  The drafts of one campaign that wait for the user to validate them in BumbleBox (recipient, subject, plain-text body, sender), newest first, with the true totals.

• list_foldersFree

  The folders of each connected mailbox, as last synced. Trash, spam, sent and drafts are left out.

• list_missionsFree

  The user's prospection campaigns (missions), most recently active first, with the number of drafts waiting, emails sent and prospects who replied.

• list_replies_to_validateFree

  Replies received on campaigns that still need the user: prepared reply drafts waiting for validation, and replies with no answer yet (with the stored AI triage: kind, summary, whether a human is needed).

• list_to_answerFree

  Received emails BumbleBox classified as needing a reply and still in the inbox, newest first.

• move_emailwrite actionFree

  Moves one inbox email to an existing folder of the same mailbox (see list_folders), on the mail server too. No folder is created. Undone by restore_to_inbox.

• restore_to_inboxFree

  Moves an archived, filed or trashed email back to the inbox, on the mail server too.

• search_contactsFree

  Contacts BumbleBox knows from the mail history (name, address, organization domain, exchange counts, last exchanges, VIP mark, note), matched on name, address or domain.

• search_emailsFree

  Searches every connected mailbox (sender, subject, preview), newest first. Operators: from:, subject:, before:YYYY-MM-DD, after:YYYY-MM-DD; the rest is free text. Deleted emails are not returned.

• send_replywrite actionFree

  Replies to the sender of one received email, and only to them (no Cc, no Bcc, no attachment), from the mailbox that received it. What happens next is the level the user set in BumbleBox for this kind of reply: a draft, a reply waiting for one tap (the default), or a reply that leaves after a delay the user can cancel. Anything that commits the user (amounts, bank details, acceptance, contracts, dates, links) always waits for the user. The result says which one applied.

• trash_emailwrite actionFree

  Moves one inbox email to its mailbox's trash when BumbleBox certifies it as noise (spam, newsletter, promotion, with a unanimous safety vote and no known contact or action word). Any other email is not moved: it becomes a proposal the user confirms in one tap in BumbleBox. Never a permanent deletion; undone by restore_to_inbox.

• update_campaign_draftwrite actionFree

  Changes the subject, body or recipient of a draft that is still a draft. Nothing is sent, and a draft the user already validated cannot be changed.
