Mailbox owners and admins
Run Alcarta locally, connect a mailbox, create an agent, and control what it can do.
Alcarta documentation
Give AI agents useful access to email. Keep destructive and outbound actions under human control.
Alcarta is a multitenant gateway in front of mailboxes you already have. Agents connect through REST or MCP. Alcarta keeps the provider credentials, resolves permissions on every request, and records actions in an audit log.
The central rule is simple: an agent may declare that it wants to move, permanently delete, or send
mail, but an approval can require a second identity to commit the action. The agent receives a
chk_… request, not a false claim that the action already happened.
Choose your path
Section titled “Choose your path”Agent builders
Choose REST or MCP, authenticate, then use the compact declarative tool surface.
Self-hosting operators
Deploy with Docker Compose or Kubernetes, then configure monitoring and backups.
What Alcarta is not
Section titled “What Alcarta is not”Alcarta is not an inbox host, an MX server, or a mirror of your messages. Message reads go to the configured provider live. Alcarta persists approval records and pointers to provider-hosted drafts, not a local copy of the mailbox.
