Overview

A Model Context Protocol server that allows AI agents to play notification sounds when tasks are completed. This TypeScript-based MCP server provides a simple, configurable notification system with bundled sounds that work out of the box with npx!

✨ Features

🔧 Tools

  • play_notification - Play a notification sound to indicate task completion
    • Takes an optional message parameter to display with the notification
    • Supports cross-platform sound playback (Windows and macOS)
    • Works with bundled sounds - no manual downloads required!

🎵 Built-in Sound Library

5 high-quality notification sounds bundled with the package:

  • cosmic - Space-themed notification 🌌
  • fairy - Magical, whimsical tone 🧚‍♀️
  • gentle - Soft, pleasant default sound (default) 🔔
  • pleasant - Balanced, professional tone 📞
  • retro - Nostalgic, vintage-style notification 🕹️
  • random - Randomly plays one of the 5 sounds 🎲

🚀 Quick Start

Option 1: Use Bundled Sounds (Recommended) ⭐

Just run it with npx - sounds included!

{
  "mcpServers": {
    "notifications": {
      "command": "npx",
      "args": ["-y", "@pinkpixel/notification-mcp"]
    }
  }
}

Option 2: Choose a Different Bundled Sound

{
  "mcpServers": {
    "notifications": {
      "command": "npx",
      "args": ["-y", "@pinkpixel/notification-mcp"],
      "env": {
        "MCP_NOTIFICATION_SOUND": "cosmic"
      }
    }
  }
}

Option 3: Random Sound Each Time 🎲

{
  "mcpServers": {
    "notifications": {
      "command": "npx",
      "args": ["-y", "@pinkpixel/notification-mcp"],
      "env": {
        "MCP_NOTIFICATION_SOUND": "random"
      }
    }
  }
}

Option 4: Use Your Own Custom Sound

{
  "mcpServers": {
    "notifications": {
      "command": "npx",
      "args": ["-y", "@pinkpixel/notification-mcp"],
      "env": {
        "MCP_NOTIFICATION_SOUND_PATH": "C:\\path\\to\\your\\sound.mp3"
      }
    }
  }
}

⚙️ Configuration

The notification sound can be configured using environment variables:

Environment Variables

| Variable | Description | Default | |----------|-------------|---------| | MCP_NOTIFICATION_SOUND | Choose from bundled sounds: cosmic, fairy, gentle, pleasant, retro, random | gentle | | MCP_NOTIFICATION_SOUND_PATH | Absolute path to your own MP3 file (overrides bundled sounds) | null |

Priority Order

  1. Custom Path (MCP_NOTIFICATION_SOUND_PATH) - highest priority
  2. Bundled Sound (MCP_NOTIFICATION_SOUND) - choose from 5 included sounds
  3. Default - gentle chime if nothing is specified

💻 Usage

Once configured, your MCP client can call the play_notification tool:

await client.request({
  method: "tools/call",
  params: {
    name: "play_notification",
    arguments: {
      message: "Task completed successfully! 🎉"
    }
  }
});
