Imap Email Mcp

IMAP Email MCP Server

A Model Context Protocol (MCP) server that provides email capabilities to Claude Code, Claude Desktop, Cursor, and other MCP-compatible AI tools. Connect to any IMAP/SMTP email provider to read, search, compose, and manage emails directly from your AI assistant.

Quick Start

Claude Code (CLI)

Important: Claude Code CLI uses claude mcp add, not config files.

claude mcp add imap-email -s user \
  -e IMAP_USER=you@example.com \
  -e IMAP_PASSWORD='your-app-password' \
  -e IMAP_HOST=imap.example.com \
  -- npx -y imap-email-mcp

> Note: If your password contains special shell characters (%, ^, *, $, !, etc.), wrap it in single quotes as shown above.

> Note: Restart Claude Code after adding an MCP for the new tools to become available.

Verify with:

claude mcp list
claude mcp get imap-email

Remove with:

claude mcp remove imap-email -s user

Cursor

Add new MCP server:

• Name: imap-email
• Type: command
• Command: npx -y imap-email-mcp

Then set environment variables in Cursor's MCP settings:

IMAP_USER=your-email@example.com
IMAP_PASSWORD=your-app-password
IMAP_HOST=imap.example.com

Claude Desktop

Add to your config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "imap-email": {
      "command": "npx",
      "args": ["-y", "imap-email-mcp"],
      "env": {

        "IMAP_PASSWORD": "your-app-password",
        "IMAP_HOST": "imap.example.com"
      }
    }
  }
}

• "Search for emails from john@example.com"
• "Create a draft email to sarah@example.com about the meeting tomorrow"
• "Show me my drafts folder"

Security Best Practices

1. Use App Passwords - Never use your main account password
2. Environment Variables - Store credentials in env vars, not in code
3. Review Before Sending - Use create_draft instead of send_email to review first

Troubleshooting

Authentication failed

• Verify your app password is correct
• Ensure IMAP access is enabled in your email provider's settings

Drafts folder not found

• The server tries common names (Drafts, INBOX.Drafts, [Gmail]/Drafts)
• Your provider may use a different folder name

Connection timeout

• Check your IMAP_HOST is correct
• Verify port 993 is not blocked by firewall
