mcp-mac

AI-powered automation of macOS Apple applications

This is a proof of concept to learn about AI and MacOS, and developed using with AI. I am unlikely to progress this any further.

mcp-mac enables AI agents to interact with macOS applications (Finder, Mail, Contacts, etc) using AppleScript through the Model Context Protocol (MCP). This allows AI assistants to perform tasks like searching contacts, managing files, and checking email on your behalf.

What is MCP?

The Model Context Protocol (MCP) is an open standard that allows AI applications to securely connect to external data sources and tools. mcp-mac implements an MCP server that provides AI agents with controlled access to your macOS applications.

Current Status

Available Tools

• Finder: Get selected files, get current folder location
• Mail: List accounts, get inbox unread/total count, create and send messages
• Contacts: Search people, get contact information
• Reminders: List lists, get incomplete reminders, create reminders
• Notes: List folders, search/get recent notes, create notes
• TextEdit: List documents, create documents
• Calendar: List calendars, get today's/upcoming events, create events
• Workflow: Composite tools for multi-app actions (e.g., Contacts to TextEdit)
• Discovery: Introspect application capabilities

Quick Start

Prerequisites

• macOS (tested on MacOS 26.2)
• Node.js 18

Installation

# Clone the repository
git clone 
cd mcp-mac

# Install dependencies
npm install

# Build the project
npm run build

E.g usage with Q CLI

# Add to your Q CLI MCP configuration
q config mcp add mcp-mac ./dist/index.js

# Use in Q chat sessions
# The tools will be available as mcp-mac___tool-name

Example Workflow

Once set up, you can ask an AI assistant to: > "Get John Smith's contact information and also check how many unread emails I have"

The AI will use the mcp-mac tools to:

1. Search for "John Smith" in Contacts
2. Retrieve his contact details
3. Check your Mail inbox count
4. Provide a combined response

Privacy & Security

mcp-mac accesses your personal data (contacts, email, files) through standard macOS AppleScript interfaces. All data processing happens locally on your machine. No data is transmitted to external servers.

Important: Only use with trusted AI applications and review any automation requests before execution.
