WHAT IT DOES

What calls_batch_read does on HubSpot MCP

RISK

Why calls_batch_read is rated Low

This tool retrieves existing call records from HubSpot CRM without any side effects. It performs a read-only query operation that returns data. The batch capability does not change the classification—it is still fundamentally a retrieval operation. Low severity because unauthorized access to call records, while potentially sensitive, does not immediately enable destructive, financial, or system-compromising actions.

From the tool's definition Tool name contains 'read' and description explicitly states 'Read multiple call records in a single request' with no modification, deletion, or execution capabilities.
