WHAT IT DOES

What crm_create_association does on HubSpot MCP

RISK

Why crm_create_association is rated Medium

This tool creates new associations (relationships) between CRM objects, which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, or move money. The severity is medium because incorrect associations could corrupt CRM data integrity and affect business processes, but the operation is reversible through deletion or correction.

From the tool's definition Tool name 'crm_create_association' and description 'Create an association between two objects' indicate a data creation operation that modifies CRM relationships.
