MCP Real-time Notifications Test
This is a test MCP server that demonstrates real-time notifications in Cline.
Setup
- Install dependencies:
pip install -r requirements.txt- Run the server:
python server.py- 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
- Make sure the server is running (you should see "Starting server on http://127.0.0.1:8000")
- In Cline, use the MCP tool:
- Server:
notification-test - Tool:
start_notifications - Arguments:
{"count": 5}
- 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_messagewithout arelated_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
