WHAT IT DOES

What hubspot_create_deal does on Access

AI agents use hubspot_create_deal to create or update resources in Access — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Access environment.

WHY IT NEEDS A POLICY

Why hubspot_create_deal needs a policy

This tool creates new data (a deal record) in HubSpot, which is reversible (deals can be deleted or archived by the user). The severity is medium because misuse by an AI agent could create unwanted deal records, pollute the CRM, and cause business confusion, but the impact is limited to CRM data and can be remedied.

From the tool's definition Tool description states 'Create a new deal in HubSpot CRM' and 'the deal is immediately created in the specified pipeline' — this is a create operation that modifies data in an external system (HubSpot).
