I am on the latest update: 1.7.39.

The loop is happening rarely, few times only. U can fix it, stopping the current generating and changing the question like even if u add a comma “.”, it will start working right. This works always for me

Hi, this looping phenomenon has reappeared, but not in auto mode, but in the use of a certain model. Specifically, it is a bug caused by switching between ask and agent modes in the same session using the suopernova-1m model.

I spent the last 2 hours trying to identify the issue. Restarting Cursor, restarting my Mac, and even downgrading Cursor didn’t work. Once I turned off Auto Mode, the agent started working fine.
@deanrie do you still working on this issue?

@canserufukisler @liudhzhyym Could you share the request ID? You’ll need to disable privacy mode first.

Cursor IDE

Describe the Bug

When I asked the Agent to use my MCP server for work purposes. The Agent called a few times and then got an error “Unrecoverable agent model looping detected.” This completely affected my work process. When I went back to the Cursor screen to check how far the Agent had gone, I saw this error. What are you guys trying to detetch? You guys are doing meaningless work and affecting my work.
