where is cursor mcp.json settings？

[threhan]

Here is my setting:
"ai-prompts-mcp": {
"type": "sse",
"url": "http://localhost:3000",
"headers": {
"Content-Type": "text/event-stream",
"Cache-Control": "no-cache",
"Connection": "keep-alive"
}
}

Then an error:
SSE error: Invalid content type, expected "text/event-stream"

Use "http://localhost:3000/sse" instead.
I'm working.
