WHAT IT DOES

What updateUserConsentWithId does on Fusionauth

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

RISK

Why updateUserConsentWithId is rated Medium

This tool modifies user consent records, which are sensitive personal data in an identity and access management system (FusionAuth). An AI agent misusing this could alter user consent preferences for data processing, privacy settings, or regulatory compliance (GDPR, CCPA).

From the tool's definition The tool description states it "Updates a single User consent by Id," which is a modification operation on user data. The tool name includes "update," confirming it performs a write (reversible modification) rather than read or destructive action.
