# Overview

aac.muthub.org: a public, working prototype of an architecture control plane, with catalogs, OPA policies, waivers, an executive scorecard, a CLI and an MCP server that brings the rules into coding agents. It is modeled in its own notation and passes its own rules.[^s1]

Organization: Personal project. Period: 2026.

# Read the original

The case study is on muthub.org: [Architecture-as-Code Reference Platform (open prototype)](https://muthub.org/initiatives/aac-reference-platform).
