Multica Security Model for Workspace Isolation and RBAC: A Technical Deep Dive

April 11, 2026 multica-ai/multica ↗

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.
