MCPing - macOS Notification MCP Server

I got a notification! 🎉

MCPing is a Model Context Protocol (MCP) server that enables AI assistants to send desktop notifications on macOS. Finally, your AI can tap you on the shoulder instead of just sitting there quietly being brilliant.

Installation

Prerequisites: Node.js 18+ and macOS (for notifications)

Quick Start (Recommended)

Add to your MCP client settings:

{
  "mcpServers": {
    "toolprint-mcping": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@toolprint/mcping-mcp@latest"]
    }
  }
}

Manual Installation

npm install -g @toolprint/mcping-mcp@latest
mcping-mcp

Configuration

For Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "mcping": {
      "command": "npx",
      "args": ["-y", "@toolprint/mcping-mcp@latest"]
    }
  }
}

For Development (HTTP Mode)

# Run in HTTP mode for testing
npx @toolprint/mcping-mcp@latest --transport http --port 3000

# Test with curl
curl -X POST http://localhost:3000/mcp \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "send-notification",
      "arguments": {
        "title": "Hello World",
        "message": "This is a test notification"
      }
    }
  }'

Usage

Once configured, ask your AI assistant:

• "Send a notification saying the build is complete"

• "Send a critical alert that the server is down"

• "Send a quiet reminder to take a break"

• "Notify me with title 'Tests Passed' and message 'All 127 tests passed'"

Tool: send-notification

Send desktop notifications on macOS with rich formatting options.

Parameters:

• title (required): Notification title (1-100 characters)

• message (required): Notification message (1-500 characters)

• subtitle (optional): Additional context (max 100 characters)

• urgency (optional): "low" | "normal" | "critical" (default: "normal")

• sound (optional): Play notification sound (default: true)

• timeout (optional): Display duration in seconds, 1-60 (default: 10)

Examples:

// Basic notification
{
  "title": "Task Complete",
  "message": "Your build finished successfully"
}

// Critical alert with subtitle
{
  "title": "Server Down",
  "message": "Production server is not responding",
  "subtitle": "api.example.com",
  "urgency": "critical",
  "sound": true,
  "timeout": 60
}

// Quiet reminder
{
  "title": "Break Time",
  "message": "You've been coding for 2 hours",
  "urgency": "low",
  "sound": false,
  "timeout": 10
}

Troubleshooting

Notifications Not Appearing?

1. Check Permissions: System Preferences → Notifications → Terminal (allow notifications)

2. Do Not Disturb: Ensure DND is disabled or use urgency: "critical"

3. Verbose Mode: Run with --verbose flag for detailed logs

Common Issues

• "Permission denied": Grant Terminal notification permissions in System Preferences

• "Not available": Ensure you're running on macOS

• "Rate limited": Wait between sending multiple notifications
