Automate provisioning with Windsurf

The Mail-in-a-Box MCP server lets Cascade manage your entire email infrastructure. You just give it a target domain. Cascade reads your project requirements and figures out exactly who needs an inbox. It chains the `create_mail_user` and `create_or_update_alias` tools in a single sweep. You watch it provision the accounts, set up the forwarding rules, and hand you the credentials. No manual admin panel required.

Audit domains and users

Keeping track of active mailboxes gets messy fast. You can ask your agent to pull a full inventory of your current setup. It uses `list_mail_domains` and `list_mail_users` to map out the exact state of your server. If you need to clean up old accounts, Cascade handles the teardown. It finds inactive addresses and calls `delete_mail_user` or `delete_mail_alias` to remove them. You get a clean environment in seconds.

Monitor system health instantly

Mail servers break in creative ways. Before you push a new app feature that relies on outbound email, you need to know the underlying infrastructure is actually running. Cascade runs `get_system_status` to verify your DNS, SSL certificates, and core services. If something looks wrong, it stops the deployment and warns you. You fix the issue before it becomes a production outage.
