Cursor agent enters endless loop without progressing past review step

[Justin_Clarke]

Describe the Bug

When the agent attempts to review/plan the next steps of an issue, it gets stuck in a loop of repeating the same message. It does eventually stop, but it never self-corrects or properly responds to my prompts. This has started since the new version was released yesterday. Third time this has happened.

Steps to Reproduce

This typically happens when I prompt the agent to do a task. It doesn’t follow the request, so I have to undo changes and provide a new prompt.

hi @Justin_Clarke and welcome to Cursor Forum.

Thank you for your bug report.

Could you post a Request ID with privacy disabled so we can look into the details? Cursor – Getting a Request ID

Please let me know if you used any MCP or API key.

Using Cursor Pro. The only MCP I have enabled is one for Shadcn Vue MCP Server, HelloGGX/shadcn-vue-mcp

[condor]

Does this occur on new Chat or just on a longer chat.

Please try also without MCP. Some of them cause similar issues.

[Justin_Clarke]

This was semi new, it was prompt/response two of a new chat.

[Justin_Clarke]

I will attempt again with your suggestions in a Git branch, with the issue I am trying to fix, having MCPs disabled. To see if the issue recurs.

[condor]

Great , thank you!

+1, getting tons of loops

[condor]

@khh2025 which model are you using?

[ewzxyh]

This bug is very commun for me when i’m using Gemini 2.5 Pro or Gemini 2.5 Flash

[condor]

@ewzxyh are you using any MCP when this issue occurs?

[ewzxyh]

Yes, they are enabled, but it doesn’t necessarily happen when the model calls the MCP. Also, is more commun with the Gemini 2.5 Flash than 2.5 Pro. Soon as i got this error again i will send the request id of the chat.
