Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

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
