BumbleBox MCP server

Email intelligence for people running several businesses, inside your AI assistant. BumbleBox triages every connected mailbox (Gmail, Outlook, any IMAP); this remote MCP server lets Claude, ChatGPT, Cursor, VS Code or any MCP client work with it.

• Endpoint: https://api.bumblebox.ai/api/mcp (streamable HTTP)
• Auth: OAuth 2.1 with dynamic client registration and PKCE. You approve once on bumblebox.ai and see exactly which permissions the assistant gets.
• Plans: Pro or Business (pricing).
• Setup for every client: https://bumblebox.ai/integrations

Install

Claude Code (plugin, with the /bumblebox:to-answer and /bumblebox:tidy commands):

/plugin marketplace add BumbleBox/bumblebox-mcp
/plugin install bumblebox@bumblebox

Or just the server: claude mcp add --transport http bumblebox https://api.bumblebox.ai/api/mcp

Claude (claude.ai, desktop): Settings → Connectors → Add custom connector → https://api.bumblebox.ai/api/mcp.

ChatGPT: Settings → Apps & Connectors → create a connector (developer mode), paste the server URL, authentication OAuth.

Cursor (~/.cursor/mcp.json):

{ "mcpServers": { "bumblebox": { "url": "https://api.bumblebox.ai/api/mcp" } } }

VS Code (.vscode/mcp.json):

{ "servers": { "bumblebox": { "type": "http", "url": "https://api.bumblebox.ai/api/mcp" } } }

Tool	What it does
search_emails, get_email	Search and read every connected mailbox
list_to_answer	Emails waiting for your reply
search_contacts, list_folders, list_calendar_events	Contacts, folders, calendar
draft_reply	A reply draft that waits in BumbleBox for your click on Send

list_missions, list_campaign_drafts, list_replies_to_validate	Your campaigns
create_campaign_draft, update_campaign_draft	Campaign drafts, sent only from BumbleBox

What it never does

BumbleBox sends nothing without your click — Send, Schedule, or a standing permission you set yourself in BumbleBox for a precise scope (existing participants of a thread you opened, a message with no commitment), capped, logged and cancellable. Anything else waits for your validation, and an assistant can never change that permission.

There is no permanent deletion: trash_email moves only certified noise to the Trash and turns anything else into a one-tap proposal in BumbleBox; everything is undone with restore_to_inbox.
