Interacts with Discord using Electron fallback with Chrome DevTools Protocol for UI automation.
Provides optional Chrome DevTools Protocol fallback for deeper UI inspection of Electron apps (e.g., VSCode, Slack, Discord).
Automates Figma actions such as exporting frames as PNG via UI automation and AppleScript.
Automates macOS system tasks including AppleScript, JXA, shell commands, window management, clipboard, notifications, and more.
Retrieves current URL and title, and performs other browser automation tasks.
Interacts with Slack using Electron fallback with Chrome DevTools Protocol for UI automation.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mac-pilot-mcptoggle dark mode"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
The Problem
There are 7+ macOS automation MCP servers. None of them remember anything. Every session starts from zero — same trial and error, same failures, same wasted tokens.

The Solution
Mac-Pilot is different. It learns from every interaction:
Success? The pattern is auto-saved as app-specific knowledge
Failure? The error is recorded so it won't repeat the same mistake
Multi-step workflow? Save it as a recipe — replay it in one call next time
Ships with 21 built-in recipes so you're productive from the first run.
Quick Start
Install
npm install -g mac-pilot-mcpConnect to your AI client
claude mcp add mac-pilot -- mac-pilot-mcpOr manually add to ~/.claude.json:
{
"mcpServers": {
"mac-pilot": {
"command": "mac-pilot-mcp"
}
}
}Add to claude_desktop_config.json:
{
"mcpServers": {
"mac-pilot": {
"command": "npx",
"args": ["-y", "mac-pilot-mcp"]
}
}
}Add to your MCP settings (.cursor/mcp.json):
{
"mcpServers": {
"mac-pilot": {
"command": "npx",
"args": ["-y", "mac-pilot-mcp"]
}
}
}Add to your MCP config:
{
"mcpServers": {
"mac-pilot": {
"command": "npx",
"args": ["-y", "mac-pilot-mcp"]
}
}
}Grant Permissions
Mac-Pilot needs Accessibility access for UI automation:
System Settings → Privacy & Security → Accessibility
Toggle ON for your terminal app (Terminal, iTerm2, VS Code, Cursor, etc.)
Restart the terminal
How It Works
You: "Export the current Figma frame as PNG"
┌─ First time ─────────────────────────────────────────┐
│ │
│ 1. mac_recipe_search("Figma export") → No matches │
│ 2. mac_state() → Figma is frontmost │
│ 3. mac_run(applescript) → File > Export > PNG │
│ 4. mac_recipe_save("export-figma-png", steps=[...]) │
│ │
│ ✓ Worked! Pattern saved automatically. │
└───────────────────────────────────────────────────────┘
┌─ Next time ───────────────────────────────────────────┐

| Capture screen/window/region as base64 PNG |
| Save a working action sequence as a reusable recipe |
| Replay a saved recipe with parameter substitution |
| Full-text search across recipes and action history |

mac_find_ui { "app": "Finder", "searchText": "Downloads" }Electron apps (VSCode / Cursor / Slack / Discord) — macOS Accessibility
exposes a thin tree for Electron, so Mac-Pilot can optionally fall back to
Chrome DevTools Protocol when the app is launched with
--remote-debugging-port=<PORT>. See docs/ELECTRON-SUPPORT.md.

}Security
Mac-Pilot blocks dangerous operations before they execute:
Layer | Protection |
Hard block |

Risk classification | Every action is rated |
Audit log | All actions (including blocked ones) are logged to SQLite |
Dry run | Test any action with |
Auto-cleanup | Action logs older than 30 days are pruned automatically |
Architecture
~/.mac-pilot/pilot.db (SQLite, WAL mode)
├── action_log — Every action executed, with timing + success/failure
├── action_log_fts — Full-text search index over action history
├── recipes — Saved automation sequences
├── recipes_fts — Full-text search index over recipes
├── app_knowledge — Per-app quirks, selectors, workarounds (auto-learned)
└── security_log — Blocked command audit trailBuilt-in recipes are auto-loaded on first run. Your custom recipes and learned knowledge persist across sessions.
Comparison
Feature | mac-pilot-mcp | Other MCP servers |
Self-learning (auto-saves knowledge) | Yes | No |
Reusable recipes with parameters | Yes | No |
Built-in recipe library | 21 | 0 |
JXA + AppleScript | Both | Usually one |
Full-text search (recipes + history) | Yes | No |

Troubleshooting
Your terminal needs Accessibility permission:
System Settings → Privacy & Security → Accessibility
Toggle ON for your terminal
Restart the terminal app completely
The target app must be running. Open it first:
mac_run { "actionType": "open", "target": "AppName" }Reduce the scale (default is 0.5):
mac_screenshot { "target": "screen", "scale": 0.3 }Recipe names are case-sensitive. Search first:
mac_recipe_search { "query": "your keyword" }Use dry run to check the risk classification:
mac_run { "actionType": "shell", "command": "your-command", "dryRun": true }Requirements
macOS (darwin only)
Node.js >= 18
Accessibility permission for UI automation
