Lumbox

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 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:

bash

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

bash

npx lumbox inbox create --name assistant

Returns JSON: {"id": "inb_...", "address": "[e-mail]"}. Use that address anywhere a signup form wants an email.

Wait for an OTP / verification code

bash

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

bash

npx lumbox send --inbox inb_... --to [e-mail] --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:

text

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)

bash

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.
