Hey, thanks for the report.

ERROR_BAD_REQUEST is usually related to MCP settings or the Override OpenAI Base URL setting. Please try:

  1. Settings > MCP: disable all MCP servers and restart Cursor
  2. Settings > Models > API Keys: make sure Override OpenAI Base URL is turned off, and temporarily disable any custom keys if you have them
  3. Create a new chat and check if it works there

If the issue still happens, please send:

  • Screenshots of Settings > Tools & MCP and Settings > Models > API Keys
  • Confirmation on whether it works in a new chat
  • A new Request ID after doing the steps above
  • Errors from Help > Toggle Developer Tools > Console

Let me know which step fixed it.
