What is the Mail-in-a-Box MCP Server?

  • Alias Management — Create, update, and remove email forwarding addresses and group aliases
  • System Monitoring — Retrieve real-time health status, diagnostic checks, and configuration metadata for your server
  • Domain Oversight — List all hosted mail domains and subdomains configured on your instance
  • Access Control — Manage administrative privileges and account settings for your email users

How it works

  1. Subscribe to this server
  2. Enter your Mail-in-a-Box Host, Admin Email, and Admin Password (or API Key)
  3. Start managing your private email infrastructure from Claude, Cursor, or any MCP-compatible client

Who is this for?

  • System Administrators — Manage mailboxes and forwarding rules via simple natural language commands

FAQ

Frequently asked questions

01

What format is required for the instance host?

Provide the full hostname without the 'https://' prefix, for example: box.yourdomain.com.

02

Can I add multiple forwarding targets to an alias?

Yes, when using the create_or_update_alias tool, provide a comma-separated list of emails in the forwards_to field.

03

Does this work with 2FA enabled accounts?
