About Mail-in-a-Box MCP Server
Connect your Mail-in-a-Box instance to any AI agent to automate your private email server management. This MCP server enables your agent to manage mailboxes, configure forwarding aliases, and monitor system health and diagnostics directly from natural language interfaces.
Pydantic AI validates every Mail-in-a-Box tool response against typed schemas, catching data inconsistencies at build time. Connect 9 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
What you can do
- User Administration — List all mail users, create new mailboxes, and update passwords programmatically
- 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
The Mail-in-a-Box MCP Server exposes 9 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
