WHAT IT DOES

What enable_2fa does on CloudStack MCP Server

WHY IT NEEDS A POLICY

Why enable_2fa needs a policy

This tool creates or modifies user authentication configuration by enabling 2FA, which is a reversible write operation. It does not execute arbitrary code, delete data, move money, or read sensitive information. However, severity is medium because misconfigured 2FA could impact account access controls, and in a multi-tenant cloud environment, enabling 2FA on wrong accounts could cause operational issues.

From the tool's definition Tool name is 'enable_2fa' and description states 'Enable two-factor authentication for user', which modifies user security settings.
