Macos MCP server

mcp-macos

A safe-by-default Model Context Protocol server that lets an agent observe and operate a Mac — read files, list processes and apps, take screenshots (read-only); write files, set the clipboard, post notifications, open things (read-write); and, behind explicit opt-ins, run commands / AppleScript, delete to Trash, kill processes and drive the GUI (admin).

It starts read-only. Every high-impact power needs both admin mode and its own flag, and the most dangerous ones ask the human to approve each call. Part of the dockndevai MCP server suite — one governance model across all of them.

Pure Node + osascript/screencapture — no native add-ons. macOS only.

What it gives an agent

The server starts read-only (see Safe by default); higher-capability tools are only registered when you raise the mode.

Install

npx -y @dockndevai/mcp-macos

Requires macOS and Node ≥ 22. click/move_mouse also need cliclick (brew install cliclick).

Configure

{
  "mcpServers": {
    "macos": {
      "command": "npx",
      "args": ["-y", "@dockndevai/mcp-macos"],
      "env": {
        "MACOS_MODE": "read-only"
      }
    }
  }
}

See docs/CLIENTS.md for Claude Code / Cursor / Codex / VS Code / Windsurf snippets, and .env.example for every supported variable.

Safe by default

This server can drive an entire Mac, so the access model (enforced by src/security.ts) is deliberately strict — defence in depth, not documentation:
