WHAT IT DOES

What brighty_unfreeze_card does on Brighty MCP Server

WHY IT NEEDS A POLICY

Why brighty_unfreeze_card needs a policy

Unfreezing a card re-enables financial transactions on it. This is a reversible state change (the card can be re-frozen), so it's Write rather than Destructive. However, the blast radius is high because re-enabling a card allows new payments and authorisations to proceed, which could have significant financial consequences if misused by an AI agent.
