My company has 100+ developers on Cursor. One of our devs switched to opus-max thinking "fast" meant cheaper. It costs 35x more per request. He burned $1,200 in a single day before anyone noticed.

That's when I built this. It connects to Cursor's Enterprise APIs and gives you per-developer spend breakdown by model, three-layer anomaly detection (thresholds, z-score, trend analysis), Slack/email alerts on spend spikes, and incident tracking with MTTD/MTTI/MTTR.

We've saved our team ~$6K/month just by identifying devs running long sessions with massive context caches and helping them start fresh chats.
