RISK

Why hubspot_create_note is rated Medium

This tool creates new notes in HubSpot CRM, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. The severity is medium because misuse could pollute CRM data with false or misleading notes that might influence business decisions, though the operation is reversible through note deletion/updates.

From the tool's definition Tool name 'hubspot_create_note' combined with description 'Create a note and optionally associate it with a HubSpot object' explicitly indicates data creation/writing action.
