What your assistant can do once connected, with the same permissions as your account.

ReadNothing in your account changes.
  • Plans and domains
    See the webmail plans and every email domain in your account with its status.
  • Check DNS records
    Compare a domain’s required DNS records against public DNS to find what’s missing.
  • List mailboxes
    See the mailboxes of a domain with their status, storage and quota.
  • How it fits together
    Explain how Webmail connects to your other Kubana products and how it uses credits, based on your account.
Makes changesReview these when your assistant asks to run them. Tagged ones need a code Kubana emails you.
  • Order webmail Approval code
    Order a webmail plan for one of your domains. The email shows the price before you approve.
  • Activate a domain Approval code
    Activate a domain that needs configuration, once all its DNS records are live. The yearly price is charged.
  • Create a mailbox
    Add a new address to an active domain.
  • Change a mailbox quota
    Give a mailbox more or less of the plan’s storage.
  • Reset a mailbox password Approval code
    Issue a new password for a mailbox on an active domain.
  • Delete a mailbox Approval code
    Remove a mailbox and the mail stored in it.

New and reset passwords are generated by Kubana and shown once, in your assistant; the dashboard never sees them. Store them somewhere safe. Your assistant can’t read or send your email.

Approval codes

By default, before your assistant runs a tagged action, Kubana checks with you by email. Nothing changes until you hand over the code. You can change which actions ask under MCP Servers in the dashboard.

  1. 1. You ask
    For example: “Delete the DEBUG variable on my-api.”
  2. 2. Kubana emails you a code
    The “Approve an AI Agent Action” email names the action in plain words, its details and price, which assistant asked and when.
  3. 3. You give the code to your assistant
    Your assistant tells you it needs the code. Read it from the email and paste it in the chat.
  4. 4. The action runs
    Your assistant repeats the request with the code, and Kubana carries it out.
  • Each code works once, and only for the exact action in the email: the same app, server, domain or mailbox, with the same values.
  • Codes expire after 10 minutes and stop working after 5 wrong tries.
  • Kubana sends at most 5 codes every 10 minutes.
  • Actions you take in the dashboard never ask for a code.

Got a code you didn’t ask for? Ignore the email and revoke that assistant under MCP Servers in your dashboard.

Stays in the dashboard

Your assistant can’t do these. It sends you to the Webmail dashboard instead.

  • Reading and sending email, in webmail

Connect your assistant

The first time it connects, your assistant opens Kubana in your browser so you can sign in and approve access.

  1. Open Settings → Connectors and click “Add custom connector”.

  2. Name it Kubana and paste the server URL:
