WHY IT NEEDS A POLICY

Why crm_batch_create_leads needs a policy

This tool creates new lead records in HubSpot's CRM system. Creation is reversible (leads can be deleted), so it falls under Write rather than Destructive. The severity is medium because bulk lead creation could enable spam/phishing attacks, data pollution, or automated enrollment of unwilling contacts into marketing workflows, but the impact is limited to lead records rather than financial or highly sensitive data.

From the tool's definition Tool name 'crm_batch_create_leads' explicitly indicates creation of leads; description confirms 'Create multiple leads in a single request'; this is a batch write operation on CRM data.
