WHAT IT DOES

What createIPAccessControlListWithId does on Fusionauth

AI agents use createIPAccessControlListWithId 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 createIPAccessControlListWithId is rated Medium

This tool creates a new IP access control list, which is a reversible write operation that modifies system configuration. IP ACLs control network access and their creation could impact security policies and system access rules, warranting a high severity due to potential for misconfiguration affecting authentication and authorization flows in a FusionAuth identity system.

From the tool's definition Creates an IP Access Control List with optional Id specification. The verb 'Creates' indicates data modification. The function name contains 'create' and the description explicitly states 'Creates an IP Access Control List.'

RECOMMENDED RULE

The rule that runs createIPAccessControlListWithId safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Fusionauth, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For createIPAccessControlListWithId, this is the rule to start with:

createIPAccessControlListWithId Rate-limited

createIPAccessControlListWithId stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
