WHAT IT DOES

What patchIPAccessControlListWithId does on Fusionauth

AI agents use patchIPAccessControlListWithId 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 patchIPAccessControlListWithId is rated Medium

This tool modifies IP access control list configuration, which is a security-critical resource. While reversible (Write rather than Destructive), unauthorized modifications could grant or revoke network access, affecting system availability and security posture. High severity reflects the security-sensitive nature of access control modifications, though the change is not inherently irreversible.

From the tool's definition Tool name contains 'patch' (update operation) and description states 'Update the IP Access Control List with the given Id', indicating modification of an existing security control resource.
