migadu-mcp 3.5.0

Professional FastMCP server for comprehensive Migadu email management with Context logging, tool annotations, and testing infrastructure

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": "[e-mail]",
        "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 [e-mail] with the name John Smith"
• "List all mailboxes on my domain"
• "Set up an email alias [e-mail] that forwards to [e-mail]"
• "Delete the mailboxes for employees who left: [e-mail], [e-mail]"
