**Multica implements workspace isolation and role-based access control through a layered middleware architecture that validates JWT tokens, resolves workspace IDs from HTTP headers or query parameters, and enforces database-backed membership checks before injecting authorization context into request handlers.**

The multica-ai/multica repository provides a multi-tenant platform where data isolation and granular permissions are critical. This guide examines the complete Multica security model for workspace isolation and RBAC, tracing how the Go backend authenticates users, validates workspace membership, and enforces role hierarchies using middleware and database constraints.
