🔔 macOS Notification MCP

A Model Context Protocol (MCP) server that enables AI assistants to trigger macOS notifications, sounds, and text-to-speech.

✨ Features

  • 🔊 Sound Notifications: Play system sounds like Submarine, Ping, or Tink
  • 💬 Banner Notifications: Display visual notifications with customizable title, message, and subtitle
  • 🗣️ Speech Notifications: Convert text to speech with adjustable voice, rate, and volume
  • 🎙️ Voice Management: List and select from available system voices
  • 🧪 Testing Tools: Diagnostic utilities to verify all notification methods

🚀 Quick Start with uvx (Recommended)

The fastest way to use this tool is with uvx, which runs packages without permanent installation:

# Install uv if you don't have it
curl -LsSf https://astral.sh/uv/install.sh | sh

# Run the MCP server directly (no installation needed)
uvx macos-notification-mcp

⚙️ Configure Claude Desktop

Add this to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "macos-notification-mcp": {
      "command": "uvx",
      "args": ["macos-notification-mcp"]
    }
  }
}

Then restart Claude Desktop.

📦 Alternative Installation Methods

Standard installation:

pip install macos-notification-mcp

🔒 Implementation Details

  • ⏱️ Rate Limiting: Notifications are processed one at a time with a minimum interval of 0.5 seconds
  • 🔄 Queuing: Multiple notification requests are handled sequentially
  • 🪟 OS Integration: Uses native macOS commands (afplay, osascript, say)
  • 🔌 FastMCP: Built on the FastMCP framework for AI communication

⚠️ Troubleshooting

  • 🔐 Permissions: Ensure notifications are allowed in System Settings → Notifications
  • ⏳ Timing: Only one notification is processed at a time
  • 🌐 Environment: If using the command directly (not uvx), you may need to use full paths
