What the publisher says

From the Email repository's README, as published. We do not edit it. Read it on GitHub

@marlinjai/email-mcp

A unified MCP server for email access across Gmail, Outlook, iCloud, and generic IMAP providers.

Features

  • Multi-provider support -- Gmail (REST API), Outlook (Microsoft Graph), iCloud (IMAP), and generic IMAP/SMTP
  • OAuth2 authentication -- Browser-based OAuth flows for Gmail and Outlook, with automatic token refresh
  • Full email client -- Search, read, send, reply, forward, organize, and manage drafts
  • Batch operations -- Delete, move, or mark hundreds of emails in a single call
  • Lightweight search -- Compact search results by default (~20KB vs ~1.4MB) with optional full body retrieval
  • Encrypted credential storage -- AES-256-GCM encryption at rest with machine-derived keys
  • Provider-native APIs -- Uses Gmail API and Microsoft Graph where available for richer features, falls back to IMAP for universal compatibility

Installation

Install globally from npm:

npm install -g @marlinjai/email-mcp

Or run directly with npx (no install needed):

npx @marlinjai/email-mcp

Quick Start

  1. Run the interactive setup wizard to add your email accounts:
npx -y -p @marlinjai/email-mcp@latest email-mcp-setup

The -p/--package flag is required. This package declares two binaries (email-mcp for the MCP server, email-mcp-setup for this wizard). Without -p, npx runs the bin matching the package's own name (email-mcp, the server) and silently passes email-mcp-setup to it as an ignored argument — the server then sits waiting for MCP protocol input on stdin forever, producing no output at all. It looks exactly like a hang. -p tells npx explicitly which package to resolve and which of its binaries to actually run.

The wizard will walk you through provider selection and authentication. After each account, it asks if you'd like to add another — so you can set up Gmail, Outlook, and iCloud all in one go.

  1. Add the server to your MCP configuration (.mcp.json):
{
  "mcpServers": {
    "email": {
      "command": "npx",
      "args": ["@marlinjai/email-mcp"]
    }
  }
}
  1. Start using email tools in Claude Code — search your inbox, send emails, organize messages, and more.

Provider Setup Guides

Gmail

No configuration needed — the setup wizard handles everything using built-in OAuth credentials (PKCE):

npx -y -p @marlinjai/email-mcp@latest email-mcp-setup
# Select "Gmail" when prompted
# Choose "Full" or "Restricted" permission scope when asked
# A browser window opens for Google authorization
# Grant the requested permissions and return to the terminal

The wizard asks which Gmail permission scope to authorize:

  • Full (default) — everything below, plus immediate, Trash-bypassing permanent deletion (https://mail.google.com/, Gmail's maximum-permission scope).
  • Restricted — read, send, label, archive, and move-to-trash (gmail.modify + gmail.settings.basic), but no permanent deletion. Every tool in this server works identically under Restricted except an explicit permanent: true delete, which fails with a Gmail API error instead of succeeding.

Pass --scope full or --scope restricted to skip the prompt, or set EMAILMCPGMAIL_SCOPE=restricted in the environment the wizard runs in.
