How do you manage multi-tenant environments within MCP?

• A. Use a single global schema with universal permissions.
• B. Merge all tenants into a single database.
• C. Only allow read-only access for all tenants.
• D. Isolate data by tenant, enforce tenant-specific permissions, and monitor cross-tenant access.

Answer: (D)

In a multi-tenant setup, the priority is strict data isolation and tenant-scoped governance. The best approach is to isolate data by tenant, enforce tenant-specific permissions, and monitor cross-tenant access. You achieve data isolation by giving each tenant its own boundaries—such as separate databases or schemas, or a shared database with a tenant identifier and row-level security—to ensure one tenant cannot access another’s data. Enforcing tenant-specific permissions means access controls are scoped to the tenant, so users and services from one tenant cannot operate on another tenant’s resources, using least-privilege, RBAC or ABAC, and ensuring service accounts are tenant-scoped. Monitoring cross-tenant access provides visibility through audit logs, alerts, and anomaly detection, enabling quick detection and remediation of any boundary violations. The other options undermine isolation and governance: a global schema with universal permissions risks data leakage; merging tenants into one database makes cross-tenant access hard to prevent; and granting read-only access for all tenants eliminates needed write capabilities and flexibility.
