WHAT IT DOES

What vanta_update_vendor does on Freshdesk

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

RISK

Why vanta_update_vendor is rated Medium

The tool creates or modifies data (vendor information) in a reversible manner. It does not execute arbitrary code, delete data irreversibly, or move money. However, it has medium severity because unauthorized vendor updates in a compliance/security platform like Vanta could affect organizational compliance posture, vendor risk assessments, and security controls.

From the tool's definition Tool name includes 'update' and description states 'Update an existing vendor in Vanta' — this modifies vendor data reversibly.
