LoopBudget is a sidecar integration for Cursor sessions: live spend estimates → soft warn → hard stop policy → a session receipt you can hand to finance (or your future self).
Why: mid-loop agent spend is fog until the invoice or a rate limit. Vendor meters don’t give you a dollar policy on the session.
What it does
- Watches Cursor session trails via the LoopBudget Cursor binary/sidecar
- Ingests into LoopBudget → soft/hard $ caps
- Soft warn + hard stop decisions + alerts + receipt in the dashboard
Honest early-access note: hard stop is recorded and alerted in LoopBudget today; we don’t SIGKILL Cursor mid-tool-call. Soft warn comes first. Cursor + Claude Code both supported.
