Give your AI agent its own real email inbox - an address it owns, that sends and receives, with replies threading back to the agent instead of a human's mailbox. Provisioned in about a minute, free tier, no card. Use when an agent needs to send mail as itself, read what comes back, or act on inbound email.

它能做什么
Email infrastructure for AI agents with zero-human setup. Self-provision an inbox in one command (no account creation, no console, no human), send and receive email, long-poll for OTP codes with the code parsed out for you. Also bundles browser automation, a credential vault, and TOTP 2FA via MCP. Use when an agent needs its own email address to sign up for services, receive verification codes, or manage correspondence.

Lumbox
Lumbox gives agents real email inboxes. The difference from other email providers: an agent provisions itself. No human creates an account, no console visit, no dashboard.
Setup (agent does this itself)
If LUMBOX_API_KEY is not set:
npx lumbox signup --source openclaw
This creates an org + API key and saves it to ~/.lumbox/config.json. Tell your human where
the key lives. All later commands read it automatically; LUMBOX_API_KEY env overrides the file.
Free tier: 3 inboxes, 5,000 inbound + 100 outbound emails/month. Signup is limited to 3 orgs/hour per IP. Paid plans from $9/month at https://lumbox.co/pricing.
Get an email address
npx lumbox inbox create --name assistant
Returns JSON: {"id": "inb_...", "address": "assistant-x7f2@lumbox.email"}. Use that address
anywhere a signup form wants an email.
Wait for an OTP / verification code
npx lumbox wait-otp --inbox inb_... --timeout 120
Blocks until a verification email arrives, parses the code out, prints
{"code": "847291", "from": "...", "subject": "...", ...}.
No polling loops, no regex on your side. Magic links and verification URLs are also extracted
(GET /v1/inboxes/:id/wait returns the full parsed email).
Send and reply
npx lumbox send --inbox inb_... --to person@example.com --subject "Update" --text "Done."
npx lumbox inbox list
Replies thread correctly via POST /v1/inboxes/:id/reply (REST) with the original message id.
REST API (no CLI needed)
Base URL https://api.lumbox.co, auth Authorization: Bearer $LUMBOX_API_KEY:
POST /v1/orgs self-signup, returns api_key (unauthenticated)
POST /v1/inboxes create inbox
GET /v1/inboxes/:id/wait long-poll next email (parsed: otp, links, category)
GET /v1/inboxes/:id/otp long-poll just the OTP code
POST /v1/inboxes/:id/send send
POST /v1/inboxes/:id/reply reply in-thread
See references/API.md for request/response shapes.
Full toolset via MCP (87 tools)
openclaw mcp add lumbox -- npx @lumbox/mcp-server
or HTTP at https://mcp.lumbox.co with the same Bearer key. Adds browser automation sessions,
an encrypted credential vault, TOTP 2FA codes, webhooks, custom domains, and contact lists —
so one key covers the whole "sign up for a service" flow: inbox → form fill → OTP → store creds.
