Midas

MIDAS is an open-source authority governance engine that determines whether an automated agent is within authority to perform a consequential action. Every evaluation produces exactly one outcome and one tamper-evident audit envelope — capturing what was requested, what authority was resolved, and why the outcome was reached. It is designed for use cases where automated decisions carry real operational or financial risk, such as loan approvals, fraud detection, insurance underwriting, and compliance workflows.

Authority flows in one direction through MIDAS: DecisionSurface → AuthorityProfile → AuthorityGrant → Agent. A surface defines what is governed (a business decision boundary), a profile sets the confidence threshold, consequence limit, and escalation mode, and a grant links an agent to a profile. This model maps directly to business rules management systems like FICO Blaze Advisor, making MIDAS a natural open-source alternative for organizations managing high-stakes decision automation.

MIDAS provides an integrity guarantee through hash-chained audit events: each event's SHA-256 hash derives from the previous event, and the final hash anchors in the envelope's integrity section. It ships with an interactive developer sandbox (Explorer), supports both in-memory and PostgreSQL backends, and can integrate with Kafka for event streaming. The platform is written in Go and runs as a single binary or via Docker Compose.
