WHAT IT DOES

What remove_niagara_module does on Unreal-MCP

AI agents call remove_niagara_module to permanently remove resources in Unreal-MCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why remove_niagara_module is rated Critical

The word 'remove' strongly suggests irreversible deletion of a Niagara particle system module within Unreal Engine 5. Removing a module from a VFX system is typically not easily undoable and could break dependent effects. With no description available, confidence is moderate, but the name pattern aligns with Destructive more than any other category.

From the tool's definition Tool name 'remove_niagara_module' — 'remove' implies deletion of a Niagara VFX module. Description is empty, lowering confidence.
