Unable to Use Cursor Due to Persistent Error Message

Hey, thanks for the report. I can see the video and the screenshot with the error.

As @Naufaldi_Rafif mentioned, this is often related to MCP. Please try the following:

  1. Disable MCP: Settings > Tools & MCP. Turn it off, restart Cursor, and try again.
  2. Check .cursorrules: if the project has a large .cursorrules file or rules in .cursor/rules/, they automatically add context to every message.

If the issue still happens, please share:

  • Are MCP servers enabled? (Settings > Tools & MCP)
  • Is there a .cursorrules file in the project? If yes, how big is it?
  • Request ID (Chat menu > Copy Request ID)
