WHY IT NEEDS A POLICY

Why mikrotik_disable_user needs a policy

This tool modifies user account state by disabling it. Disabling an account is reversible (it can be re-enabled later), so it falls under Write rather than Destructive. The severity is medium because disabling a user account on a network device could disrupt legitimate access, but the impact is localized to access control and the action is not irreversible.

From the tool's definition Tool name is 'mikrotik_disable_user' and description states it 'Disables a user account'. Disabling is a reversible modification (the account can be re-enabled), not a deletion.
