imicros‑acl is a Moleculer service that adds fine‑grained, rule‑based access control to microservices. It stores group memberships and permission grants in Neo4j, issues short‑lived tokens for users (full or restricted based on group grants), and provides a middleware, mixin, and API actions to request, verify, and evaluate those tokens against customizable rulesets—making it ideal for developers building secure, permission‑driven Node.js microservice architectures.
