api record

BumbleBox is an email client with AI triage over all of the user's connected mailboxes. Emails are identified by the id returned by search_emails and list_to_answer. BumbleBox sends nothing without the user's click, or a standing permission the user set in BumbleBox for a precise scope (replies to the existing sender of a thread, with no commitment), capped, logged and cancellable: send_reply follows that setting and reports what it did; draft_reply only prepares a draft. Campaign drafts are written inside their campaign and sent only from BumbleBox. trash_email moves certified noise to the…

_ is it live, free and safe measured by this hub
Is bumblebox live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is bumblebox free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does bumblebox have?
17 tools: move_email, search_emails, archive_email, list_calendar_events, restore_to_inbox, list_replies_to_validate, update_campaign_draft, list_folders, ….
Is bumblebox safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • move_email auth-required never probed

    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.

  • search_emails auth-required never probed

}
    arguments 16 lines
  • list_replies_to_validate auth-required never probed

    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).

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}
    arguments 5 lines

    }
  },

  • list_folders auth-required 1h ago

  },
  "additionalProperties": false
}
    arguments 16 lines
  • draft_reply auth-required never probed

    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.

    mcp-tool

    {

  "$schema": "http://json-schema.org/draft-07/schema#",

  "additionalProperties": false
}
    arguments 28 lines
  • send_reply auth-required never probed

    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.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

    arguments 23 lines
  • trash_email auth-required never probed

    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.

  • list_campaign_drafts auth-required never probed

    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.

}
    arguments 21 lines
  • create_campaign_draft auth-required never probed

    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.

    mcp-tool

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id da62d4b142971783.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/da62d4b142971783/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
