MCP Real-time Notifications Test

This is a test MCP server that demonstrates real-time notifications in Cline.

Setup

1. Install dependencies:

pip install -r requirements.txt

2. Run the server:

python server.py

3. Add the server to Cline's MCP settings:
   • Open the Cline MCP settings file (you can find the path in VS Code)
   • Add this configuration:

{
  "mcpServers": {
    "notification-test": {
      "type": "streamableHttp",
      "url": "http://127.0.0.1:8000/mcp",
      "disabled": false,
      "autoApprove": []
    }
  }
}

Testing

1. Make sure the server is running (you should see "Starting server on http://127.0.0.1:8000")

2. In Cline, use the MCP tool:

   • Server: notification-test
   • Tool: start_notifications
   • Arguments: {"count": 5}

3. You should see VS Code notification popups appearing in real-time as the server sends them!

How it works

• The server sends notifications using send_log_message without a related_request_id
• This makes them standalone notifications that arrive immediately
• Cline's McpHub now has notification handlers that display these as VS Code popups
• The notifications also appear in the console for debugging

What you'll see

• VS Code info notifications like: "MCP notification-test: [notification_demo] Notification 1/5 sent after 0.52s total (waited 0.52s)"
• Console logs with full notification details
• Real-time updates as each notification arrives
