WHAT IT DOES

What set_niagara_module_enabled does on Unreal-MCP

AI agents use set_niagara_module_enabled 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 set_niagara_module_enabled is rated Medium

Based on the name, this tool likely enables or disables a Niagara VFX module within the Unreal Engine editor, which is a reversible modification (it can be toggled back). The server context confirms it operates within the UE5 editor. Empty description lowers confidence. Classified as Write since enabling/disabling a module is a reversible state change rather than destructive, execute, or financial.

From the tool's definition Tool name: set_niagara_module_enabled — description is empty and uninformative.
