Apple Mail MCP Server

A Model Context Protocol (MCP) server that enables AI assistants like Claude to read, send, search, and manage emails in Apple Mail on macOS.

Note: This is the npm/Node.js package — install with npx or npm. There is an unrelated Python project of the same name on PyPI (imdinu/apple-mail-mcp) installed via pipx/uvx. If you're using uvx and seeing a cyclopts dependency error, you're looking for that project, not this one.

What is This?

This server acts as a bridge between AI assistants and Apple Mail. Once configured, you can ask Claude (or any MCP-compatible AI) to:

• "Check my inbox for unread messages"
• "Find emails from john@example.com"
• "Send an email to the team about the meeting"
• "Create a draft email for me to review"
• "Reply to that message"
• "Forward this to my colleague"
• "Move old newsletters to the Archive folder"

The AI assistant communicates with this server, which then uses AppleScript to interact with the Mail app on your Mac. All data stays local on your machine.

Quick Start

Using Claude Code (Easiest)

If you're using Claude Code (in Terminal or VS Code), just ask Claude to install it:

Install the sweetrb/apple-mail-mcp MCP server so you can help me manage my Apple Mail

Claude will handle the installation and configuration automatically.

Or register it deterministically in one command:

claude mcp add apple-mail -s user -- npx -y apple-mail-mcp

Using the Plugin Marketplace

Install as a Claude Code plugin for automatic configuration and enhanced AI behavior:

/plugin marketplace add sweetrb/apple-mail-mcp
/plugin install apple-mail

This method also installs a skill that teaches Claude when and how to use Apple Mail effectively.

Configuring IMAP/SMTP for a plugin install: a plugin install has no editable env block, so supply settings via the config file at ~/Library/Application Support/apple-mail-mcp/config.json — Method B in the IMAP / SMTP Setup Guide. Passwords stay in the macOS Keychain; run the doctor tool to verify.

Using the Codex Marketplace

Install the same public marketplace in Codex:

codex plugin marketplace add sweetrb/apple-mail-mcp
codex plugin add apple-mail@apple-mail-mcp

The Codex package registers the same apple-mail MCP server through an exactly pinned runtime — npx -y apple-mail-mcp@ — and includes the Apple Mail skill guidance. The pin in codex/.mcp.json is rewritten to match package.json by scripts/sync-plugin-version.mjs on every version bump, so the plugin manifest and the server it launches are always the same release; CI fails the PR if they drift.

Other Hosts (Hermes, Antigravity)

Two more hosts can run the same apple-mail MCP server (npx -y apple-mail-mcp):

• Hermes Agent (NousResearch) — Hermes has no plugin/marketplace drop-in, so there is nothing in this repo to install from. Register the server with the CLI:

  hermes mcp add apple-mail --command npx --args -y apple-mail-mcp
  

  Or add it to ~/.hermes/config.yaml by hand:

  mcp_servers:
    apple-mail:
      command: npx
      args: ["-y", "apple-mail-mcp"]
