🚀 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.

🔒 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
