Kairos launches open-source risk and fraud decisioning platform
What happened
Kairos, an open-source risk and fraud decisioning platform, was featured on the Hacker News front page on November 4. It covers signup, login, orders, payments and withdrawals, returning approve, step-up verification, manual review or block in real time and storing risk scores and decision reasons. Agents such as Claude Code, Cursor and Codex can use MCP to build workflows, propose model experiments and ship winning versions. Experiments split training, selection and test data by time; models combine Grayson answers with business numbers using logistic regression or gradient-boosted trees.
