Migadu

Migadu MCP Server

Control your Migadu email hosting through AI assistants using the Model Context Protocol (MCP).

What is Migadu?

Migadu is a Swiss email hosting service that offers unlimited email addresses with pricing based on actual usage rather than mailbox count. They focus on standard email protocols (SMTP/IMAP/POP3) without vendor lock-in, making them popular with developers and privacy-conscious users.

What This Does

This MCP server lets AI assistants manage your Migadu email accounts. Instead of clicking through web interfaces, you can ask your AI to:

• Create and delete mailboxes
• Set up email aliases and forwarding rules
• Configure autoresponders
• Manage multiple email identities
• Handle bulk operations efficiently

Setup

Add to your MCP client configuration (e.g., Claude Desktop):

{
  "mcpServers": {
    "migadu": {
      "command": "uvx",
      "args": ["migadu-mcp"],
      "env": {
        "MIGADU_EMAIL": "[email protected]",
        "MIGADU_API_KEY": "your-api-key",
        "MIGADU_DOMAIN": "yourdomain.com"
      }
    }
  }
}

Get your API key from Migadu Admin > My Account > API Keys.

Example Usage

Once configured, you can ask your AI assistant things like:

• "Create a new mailbox for [email protected] with the name John Smith"
• "List all mailboxes on my domain"
• "Set up an email alias [email protected] that forwards to [email protected]"
• "Delete the mailboxes for employees who left: [email protected], [email protected]"
