hi @kanwardeep007 thank you for the detailed bug report.

Currently I can not reproduce the issue.

Could you please confirm or provide following info:

  • Does this happen also in a new chat?
  • Do you have any MCPs or API keys configured?
  • Which model are you using?
  • For the request ID you posted is the Privacy setting Disabled? (We would need a request ID with privacy disabled to be able to look into the request).
  • Are there any errors in Help > Toggle Developer Tools > Console , copy errors here.

  1. Yes it happens in a new chat. (i restarted the laptop, reinstalled cursor but still the same error occurs)

Ok I found the issue
I was testing mcp servers and had 63 tools enabled using 6 mcp servers. That was causing the error message.

If I remove the mcp servers everything works.
It would be nice if cursor can say in the error message that the tools is creating a large message context or something along those lines

Thanks for the feedback and for finding the solution.

Yes we will check why this happened and how we can improve the error detection as well as message.

@kanwardeep007 Could you share how you got 63 tools enabled? The user interface only allows 40.
