文档

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" } } }

Tools

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
`send_reply`	A reply to the original sender, at the level you set in BumbleBox
`archive_email`, `move_email`, `trash_email`, `restore_to_inbox`	Tidy on request, always undoable
`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.
