Apple MCP Server

Connect Claude to your Apple services via the Model Context Protocol

Features • Installation • Configuration • Tools • Architecture

Overview

This MCP server enables Claude to interact with your Apple services in two modes:

Local Mode (Default) - macOS Only

Uses AppleScript to access native macOS apps. Faster, works offline, more services.

* Email and Calendar still use the iCloud protocols in both modes and need
credentials. Their AppleScript clients exist but are not wired up yet.

Cloud Mode - Works Anywhere

Uses iCloud protocols (IMAP, CalDAV, CardDAV). Requires app-specific password.

Features

• 40 Tools across 7 services (local-only tools return an error in cloud mode)
• Dual Mode - switch between local (fast) and cloud (remote access)
• 7 Services - Email, Calendar, Contacts, Reminders, Notes, Messages, Safari
• Secure Authentication - AppleScript permissions or app-specific passwords
• Full CRUD - create, read, update, delete across services

Installation

# Clone the repository
git clone https://github.com/MrGo2/icloud-mcp.git
cd icloud-mcp

# Install dependencies
npm install

# Configure (optional for local mode)
cp .env.example .env

Configuration

Local Mode (Default)

No configuration needed! Just run:

npm start

On first use, macOS will prompt for access to each app. Grant permission in System Settings > Privacy & Security > Automation.

Cloud Mode

1. Generate an App-Specific Password

   • Go to appleid.apple.com
   • Sign in → Security → App-Specific Passwords → Generate
   • Name it iCloud MCP and copy the 16-character password

2. Configure .env

   USE_LOCAL_MODE=false
   [email protected]
   ICLOUD_APP_PASSWORD=xxxx-xxxx-xxxx-xxxx
