(solved) Unable to Connect to Gemini-2.5 Models in Agent Mode

Support Bug Reports
1

In Agent mode, the Gemini-2.5-pro-exp-03-25 and Gemini-2.5-pro MAX models do not work. I always get the following error message:
“We’re having trouble connecting to the model provider. This might be temporary - please try again in a moment.”

This issue has been occurring since yesterday, and I have not been able to use Agent mode at all. It is affecting my use of Cursor and impacting my work.

Steps to reproduce the issue:

  1. Select Agent mode.
  2. Choose one of the Gemini 2.5 models (either Gemini-2.5-pro-exp-03-25 or Gemini-2.5-pro MAX).

The error happens immediately.

Hey, try disabling your MCP servers and see if that resolves the issue.

Hey deanrie, would you mind confirming how one does this on Cursor?

Hey, do you mean disabling MCP servers? If you haven’t added them, I don’t think you should have them.

Thank you for confirming, that is indeed what I was referring to.

Im curious why I might be having the issue then. I haven’t been able to use the Gemini 2.3 Pro max model. I have a Pro plan and have only used 37 of my monthly requests. Extremely frustrating to say the least, its driving me crazy lol. I tried reinstalling the application, all other models seem to work except for this one.

To use Max models, you need to enable the usage-based pricing option in your account settings.

Do you have MCP servers enabled? If so, try disabling them, as this might be causing the error. I just checked, and it works for me. Also, try starting a new chat.

I did check this before as I saw this was a recommended solution in the past but found I currently have none enabled. I did create a new chat for this so I will see what comes from that. Thanks for this input
