WHAT IT DOES

What reorder_niagara_module does on Unreal-MCP

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

RISK

Why reorder_niagara_module is rated Medium

This tool modifies VFX module configuration in a way that can be undone (reverted, re-ordered again), making it Write rather than Destructive. The empty description reduces confidence slightly. Medium severity reflects that misuse could corrupt complex visual effects pipelines, but the effects are reversible and confined to a specific subsystem.

From the tool's definition Tool name 'reorder_niagara_module' indicates it modifies the sequence or arrangement of Niagara VFX modules. The 'reorder_' prefix suggests a reversible structural change to Niagara systems (particle effects in Unreal Engine 5).

RECOMMENDED RULE

The rule that runs reorder_niagara_module safely

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

reorder_niagara_module Rate-limited

reorder_niagara_module 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.
