No - Cursor works, but with this issue

Hey, thanks for the report. A 503 error from marketplace.cursorapi.com suggests a server-side issue.

Could you please try again and let us know if the issue persists? This might be a temporary outage.

If it’s still happening, please check:

• Can you manually install or update extensions from the marketplace UI?
• Does restarting Cursor resolve it?

Let me know what you find!
