Email MCP Server: Complete Guide to Email for AI Agents

An Email MCP server is one of the most useful tools you can give your AI agent. It enables your AI to create email inboxes, receive messages, extract verification codes, and automate email-based workflows — all through the standardized Model Context Protocol.

In this guide, we'll cover everything you need to know about Email MCP servers: what they are, why you need one, and how to set up Docmailer as your Email MCP server.

What is an Email MCP Server?

MCP (Model Context Protocol) is an open standard developed by Anthropic that allows AI assistants to interact with external tools and services. An Email MCP server specifically provides email functionality through this protocol.

When you connect an Email MCP server to your AI agent, it gains the ability to:

• Create temporary email addresses on demand
• Check for new incoming emails
• Read email content (subject, body, attachments)
• Extract verification codes and magic links
• Send emails (with the right server)
• Delete emails when done

This is incredibly powerful for automation. Your AI can now handle tasks that require email verification, sign up for services, monitor inboxes, and more.

Why Do You Need an Email MCP Server?

Without an Email MCP server, your AI agent is blind to email. It can't:

• Complete signup flows that require email verification
• Access content behind email gates
• Monitor for important notifications
• Test email functionality in your apps
• Automate any workflow involving email

An Email MCP server bridges this gap, giving your AI the same email capabilities you have.

Docmailer: The Best Email MCP Server

Docmailer is purpose-built as an Email MCP server for AI agents. Unlike Gmail MCP servers that connect to your personal email (risky!), Docmailer provides temporary, disposable inboxes that are safe to let AI control.

Key Features

• Instant setup — One command to connect
• Temporary inboxes — Auto-expire, no spam buildup
• Safe for AI — Disposable addresses, nothing to lose
• Send & receive — Full email capability

Setting Up Docmailer as Your Email MCP Server

Step 1: Get Your API Token

1. Sign up at docmailer.org/sign-up
2. Go to the Dashboard
3. Copy your API token from the MCP Setup section

Step 2: Connect to Your AI Agent

For Claude Desktop / Claude Code:

claude mcp add --transport sse docmailer "https://docmailer.org/mcp/sse?token=YOUR_TOKEN"

For Cursor:

Add to your MCP settings:

{
  "mcpServers": {
    "docmailer": {
      "url": "https://docmailer.org/mcp/sse?token=YOUR_TOKEN"
    }
  }
}

For OpenClaw / Clawdbot:

{
  "mcp": {
    "servers": [{
      "name": "docmailer",
      "type": "sse",
      "url": "https://docmailer.org/mcp/sse?token=YOUR_TOKEN"
    }]
  }
}

Step 3: Start Using Email

Once connected, your AI can use these tools:

• create_inbox — Create a new temporary inbox
• get_inbox — Get inbox info and emails
• read_email — Read a specific email
• send_email — Send an email (Premium)
• delete_email — Delete an email

Example Use Cases

Automated Signups

Ask your AI: "Sign up for ProductHunt with a temp email and verify it"

Your AI will create an inbox, fill out the signup form, wait for the verification email, extract the link, and complete the signup.

E2E Testing

Ask your AI: "Test the password reset flow on staging.myapp.com"

Your AI creates a test account, triggers password reset, receives the email, clicks the link, and verifies the flow works.

Content Access

Ask your AI: "Get me that PDF that's behind an email gate"

Your AI enters a temp email, receives the download link, and hands you the content.
