🍎 AppleScript MCP Server

Give Claude the power to control your Mac. This MCP server lets Claude automate applications, manage files, control music, send messages, and much more through AppleScript.

What Can You Do With It?

Once installed, just ask Claude things like:

• "What's playing right now?" — Claude checks Music.app and tells you
• "Create a reminder to call Mom tomorrow at 3pm" — Creates it in Reminders
• "Add a new note called 'Meeting Notes' with today's date" — Creates it in Notes
• "Open my Downloads folder" — Opens it in Finder
• "What apps are running?" — Lists your active applications
• "Play my Chill playlist" — Starts playback in Music
• "Get the URL of my current Safari tab" — Returns the URL
• "Create a new Calendar event for Friday at 2pm" — Adds it to Calendar
• "Show me what's on my clipboard" — Displays clipboard contents
• "Send a message to John saying I'm running late" — Sends via Messages

Claude discovers what's possible, learns what works, and handles errors gracefully.

Requirements

• macOS (AppleScript is macOS-only)
• Node.js 18+ — Download here
• Xcode — Install from the App Store (required for AppleScript dictionaries)

After installing Xcode, run this to verify it's set up correctly:

sdef /System/Applications/Notes.app | head -5

If you see XML output, you're good. If you get an error, run:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Installation

Claude Code

Install via the plugin marketplace:

/plugin marketplace add adamrdrew@marketplace
/plugin install applescript-mcp@adamrdrew

Restart Claude Code or run /mcp to verify it's connected.

Claude Desktop

Add this to your config file at ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "applescript-mcp": {
      "command": "npx",
      "args": ["-y", "applescript-mcp"]
    }
  }
}

Restart Claude Desktop.

Claude Code Permissions

Claude Code will ask you every time you use an MCP server command for the first time, meaning when you start using the MCP server you will get lots of "are you sure you want to do this?" prompts, which is a pretty terrible experience. After installing the plugin you can allowlist calls to the MCP server bu adding this to your .claude/settings.json

{
  "permissions": {
    "allow": [
      "mcp__plugin_applescript-mcp_applescript-mcp-server__*"
    ]
  }
}

System Permissions

The first time Claude tries to control an app, macOS will ask for permission. Grant these in System Settings → Privacy & Security:

| Permission | When It's Needed | |------------|------------------| | Automation | Controlling any app (Finder, Music, Safari, etc.) | | Accessibility | Keyboard simulation, UI automation | | Full Disk Access | Some file operations |

When prompted, allow your terminal app (Terminal, iTerm, Warp, etc.) or Claude Desktop to control the requested application.

What Apps Work?

Claude can control any "scriptable" macOS application. Most built-in apps are scriptable:

• Finder — File and folder operations
• Music — Playback, playlists, library access
• Safari — Tabs, URLs, reading lists
• Mail — Send, read, organize emails
• Calendar — Events and reminders
• Notes — Create and manage notes
• Reminders — Tasks and lists
• Messages — Send messages
• Photos — Albums and organization
• Contacts — Address book access
• Keynote/Pages/Numbers — Document automation
• Terminal — Script execution

Many third-party apps are also scriptable (Adobe apps, BBEdit, OmniFocus, etc.).

Safety Features

The server protects you from accidental damage:

| Risk Level | What Happens | Examples | |------------|--------------|----------| | Low | Runs normally | Get info, read data | | Medium | Warning shown | Sending emails, keystrokes | | High | Blocked until you confirm | Shell commands, quit all apps | | Critical | Blocked until you confirm | Delete all files, empty trash |

If Claude tries something risky, you'll see a warning and can decide whether to proceed.

Learning System

The server gets smarter over time:

• Remembers what works — Successful scripts are saved for future reference
• Suggests fixes — When something fails, it offers specific solutions
• Skill files — Curated examples for popular apps live in ~/.applescript-mcp/skills/

Helpful Error Messages

When something goes wrong, you get actionable fixes:

❌ Automation permission denied for Safari.

HOW TO FIX:
1. Open System Settings
2. Go to Privacy & Security → Automation
3. Find your terminal app
4. Enable the toggle for "Safari"
5. Restart your terminal

Troubleshooting

"Xcode is not installed" Install Xcode from the App Store, then run:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

"Permission denied" errors Open System Settings → Privacy & Security → Automation and enable the app.

Commands don't work on an app Not all apps are scriptable. Ask Claude to run list_scriptable_apps to see what's available.

Server not connecting

• For Claude Code: Run /mcp to check status
• For Claude Desktop: Restart the app after editing config
