WHY IT NEEDS A POLICY

Why updateStage needs a policy

This is a Write operation because it modifies/updates existing data reversibly. It does not delete data (thus not Destructive), does not execute arbitrary code (thus not Execute), and does not involve financial transactions. The medium severity reflects that updating workflow stages in a CRM could impact business processes, but the effect is reversible and contextual to the specific stage being modified.

From the tool's definition Tool name 'updateStage' indicates modification of existing data. Server description mentions 'CRUD operations' including update capability. The tool updates a stage (likely a deal stage or workflow stage) without irreversible deletion.
