# Get a Mailing Address for Your AI Agent

> Reserve a limited spot for your AI agent's own real mailing and package address with street address + mailbox number. Address issuing begins August 31, 2026. Live today: outbound mail, webhooks, and inbound context from an address you already control.

## What is available now

- Outbound letters, certified mail, postcards, invoices, contracts, legal notices, and demand letters
- Delivery status via webhooks
- Human approval before sending with `requires_approval=true`
- Inbound context from an address you already use: forward scans, photos, PDFs, provider notices, and notes to mailbox.bot

## AI agent address reservation

Use the reservation path when you need a new mailing address, virtual mailbox, legal postal address, street address + mailbox number, scan-on-arrival workflow, arrival photos, eligible package receiving, or agentic mail handling for an AI agent.

mailbox.bot begins issuing reserved receiving addresses on August 31, 2026 after account approval and any required postal authorization. Planned price: $10/mo. The address product is intended to photograph arrivals, scan contents when requested or instructed, OCR/classify mail, receive eligible packages, and notify agents so workflows can decide, route, and send linked replies at scale.

## Add to any MCP agent (2 lines)

```json
{
  "mcpServers": {
    "mailbox-bot": {
      "url": "https://mailbox.bot/api/mcp",
      "headers": { "Authorization": "Bearer sk_agent_..." }
    }
  }
}
```

Your agent can now send outbound postal mail using the `send_mail` MCP tool.

## REST API example

```bash
curl -X POST https://mailbox.bot/api/v1/mail \
  -H "Authorization: Bearer sk_agent_..." \
  -H "X-Mailbox-MD-Version: 1" \
  -F 'document=@contract.pdf' \
  -F 'recipient_name=Acme Corp' \
  -F 'recipient_line1=123 Main St' \
  -F 'recipient_city=Los Angeles' \
  -F 'recipient_state=CA' \
  -F 'recipient_zip=90001' \
  -F 'mail_class=first_class'
```

## Integration protocols

- **MCP**: Add as MCP server. Agent gets `send_mail` tool automatically.
- **REST API**: POST to /api/v1/mail with `sk_agent_` key.
- **A2A**: Agent-to-agent protocol at /api/a2a.
- **OpenClaw**: Discovery via /.well-known/agent.json.

## Why this matters

Postal mail is one of the last gaps in agent capability. Address reservations capture the receiving-side demand; the live outbound API lets agents act today:
- Legal: send certified notices with tracking and delivery documentation
- Collections: demand letters with account-level delivery events
- Property management: tenant notices triggered by lease events
- Sales: personalized postcards from lead qualification data
- Compliance: required notices sent automatically from detected events

## Cost

- $0/mo base for outbound
- AI agent real mailing and package address: street address + mailbox number, scan/photo intake, and agent notifications; reservations open now, issuing begins August 31, 2026, planned at $10/mo
- First class letter (1 page): $1.00 total
- Extra pages: +$0.40/page plus any additional postage from weight

## Best for

- LangChain, AutoGen, CrewAI, OpenClaw agents that need a mail tool
- Autonomous workflow platforms where steps require postal mail
- Any agent that breaks its automation loop when a letter needs mailing
