Things sold as "unlimited" are always done so within some scope that makes it hard to abuse, on purpose. Unlimited free refills, but you can't bring a bucket to take home. Unlimited home bandwidth, but you can't use it to run servers.
Yes you can technically do this, but the result is that Cursor will just change their subscription model. Because they rely on the "unlimited" access being within a scope they control that gives them tools to manage volume.
Things sold as "unlimited" are often much more expensive for the average user than proper rate based billing would be (see - mobile data, internet data in general, those soft drinks [incl a couple refills] etc...)
It's "nice" in that neither party explicitly needs to track usage (although to your point, the company almost always does actually monitor and track), and it can alleviate billing anxiety. But... I'm at the spot where I'd rather things like internet, phone, tokens, etc just cost their damn cost (ex - bill me at the actual costs your company incurs to provide the service, plus some markup).
I've paid for cloud services at some non-trivial scale, and pricing them out becomes a big job. Understanding what you're going to pay month to month, how changing one part of your infra changes pricing, etc, is hard. I absolutely don't want to take that work into my personal life.
I'm running Claude Code with Gemma 4 atm and not paying anyone anything, and that's basically what this bridge does as far as I can tell. I dislike Cursor, but was pressured to use it at my last company, and would definitely prefer the CC interface.
Edit: never mind I think it’s so you can use the Claude CLI but with your cursor allowances…
I was tripped up by ‘Claude’ being the name of several different but related things.
This is a thin shim that makes Claude Code talk to Cursor's backend instead. One command, no setup, no background daemon, no configuration.
