A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

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.
Once installed, just ask Claude things like:
Claude discovers what's possible, learns what works, and handles errors gracefully.
After installing Xcode, run this to verify it's set up correctly:
sdef /System/Applications/Notes.app | head -5If you see XML output, you're good. If you get an error, run:
sudo xcode-select -s /Applications/Xcode.app/Contents/DeveloperInstall via the plugin marketplace:
/plugin marketplace add adamrdrew@marketplace
/plugin install applescript-mcp@adamrdrewRestart Claude Code or run /mcp to verify it's connected.
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 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__*"
]
}
}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.
Claude can control any "scriptable" macOS application. Most built-in apps are scriptable:
Many third-party apps are also scriptable (Adobe apps, BBEdit, OmniFocus, etc.).
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.
The server gets smarter over time:
~/.applescript-mcp/skills/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"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.
