Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details
From the project README🔔 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
Install from source:
git clone https://github.com/devizor/macos-notification-mcp
cd macos-notification-mcp
pip install .

🔒 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

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
