How does MCP enforce least privilege access?

• A. By making all data publicly readable
• B. By using only biometric authentication
• C. By granting access based on role and need-to-know, with periodic permission reviews
• D. By requiring password changes every day

Answer: (C)

Least privilege is about giving each user only the access necessary to do their job, nothing more. In MCP this is done by linking access to a user’s role and need-to-know, so someone can see and use only the data and tools required for their tasks. Permissions are reviewed regularly, and adjustments are made when roles change or tasks shift, ensuring that unnecessary access is revoked promptly. This minimizes risk if credentials are compromised and keeps operations auditable. The other approaches don’t enforce this principle: making data publicly readable removes access control entirely; relying on biometric authentication speaks to identity verification but doesn’t govern what a user may do or see; and demanding daily password changes is a password policy, not a mechanism to restrict privileges.
