What it does

BumbleBox is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

From the publisher's description, Electra Index matched it to one capability: ticket triage. That makes it a candidate for tasks such as triage support tickets or automate customer support.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

17 tools offered to AI assistants

  • search_emails · 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.
  • get_email · One email in full: sender, recipients, date, subject, plain-text body, attachment names, folder and BumbleBox classification.
  • list_to_answer · Received emails BumbleBox classified as needing a reply and still in the inbox, newest first.
  • search_contacts · Contacts BumbleBox knows from the mail history (name, address, organization domain, exchange counts, last exchanges, VIP mark, note), matched on name, address or domain.
  • list_folders · The folders of each connected mailbox, as last synced. Trash, spam, sent and drafts are left out.
  • list_calendar_events · Events of the connected Google calendars between two dates (default: the next 7 days, at most 62 days).
  • draft_reply · 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 previ
  • send_reply · 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 o
  • archive_email · Moves one inbox email to its mailbox's archive folder, on the mail server too. Undone by restore_to_inbox. Nothing is deleted.
  • move_email · 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.
  • trash_email · 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
  • restore_to_inbox · Moves an archived, filed or trashed email back to the inbox, on the mail server too.

  • list_missions · The user's prospection campaigns (missions), most recently active first, with the number of drafts waiting, emails sent and prospects who replied.
  • list_campaign_drafts · 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_replies_to_validate · 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).
  • create_campaign_draft · 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.
  • update_campaign_draft · 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.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. $9.99/month.
