Since Update, I cant use my Agent & Chat anymore?


I am not sure why I cant use my Agents / Chats anymorel, its stuck. I tryed to check it manually, with the little I know and researched, restarted also etc . I am still Pro-User till the 9th payed a lot money the past month so I am devistated and if its because of that I lost 4 Days of the cursor usage.

Hey, thanks for the report. I can see the screenshot with the “Bad Request” error.

The ERROR_BAD_REQUEST issue is usually fixed with these steps:

  1. Settings > Tools & MCP: disable all MCP servers and restart Cursor
  2. Settings > Models > API Keys: make sure “Override OpenAI Base URL” is turned off. If you’re using custom keys, try disabling them temporarily
  3. Create a new chat: the issue is often caused by accumulated context in an old chat

Many users fixed it just by creating a new Agent chat: "error_bad_request

If that doesn’t help, please send:

  • Screenshots of Settings > MCP and Settings > Models > API Keys
  • Whether it works in a new chat
  • Logs from Help > Toggle Developer Tools > Console

Let me know which step worked.
