What users can do
Users can ask their AI assistant to:
- Search their inbox and summarize threads
- Draft replies and forwards for them to review
- Organize mail, folders and contacts
The AI works through the user’s own mailbox, and mail stays on your servers.
Built-in safeguards
- Users choose what each AI app can access when they connect it.
- Sending is a separate permission, with an hourly limit.
- Users can hide folders, review an activity log and disconnect apps at any time.
- Each connection reaches only the mailbox of the user who approved it.
For hosting providers
- Runs inside Roundcube: there’s no separate MCP server to host or maintain.
- No AI costs for you: users bring their own AI subscription.
- Retention: AI access is now a reason for customers to stay with your hosted email rather than leave for Gmail or Outlook.
Requirements
- Roundcube 1.6 or 1.7
- PHP 8.0+ with the cURL extension
- MySQL, PostgreSQL or SQLite
- The default cPanel Roundcube isn’t supported.
