Finic open-sources real-time risk control decision system Kairos, tuned by coding agents

Finic has open-sourced the real-time risk control decision system Kairos, which makes real-time pass, step-up verification, manual review, or block decisions for events such as registration, login, orders, payments, and withdrawals, while retaining the signals behind each decision. Kairos connects to agents such as Claude Code, Cursor, and Codex via MCP; the agents build workflows, design model variants, and have the server train and test them, then release the winning version. The system ships with Finic's decision model Grayson, which can be combined with logistic regression and XGBoost-compatible gradient boosted trees, and offers TypeScript and Python SDKs, a CLI, and Docker self-hosting under the Apache 2.0 license.
