WHAT IT DOES

What clear_niagara_module_input does on Unreal-MCP

AI agents call clear_niagara_module_input 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 clear_niagara_module_input is rated Critical

The word 'clear' typically indicates an irreversible removal operation. In the context of Niagara (Unreal Engine's VFX system), clearing a module input would remove configured parameters, which may not be easily undone. However, the empty description significantly reduces certainty — it could be a reset/write operation rather than a true destructive one.

From the tool's definition Tool name 'clear_niagara_module_input' — 'clear' implies removal/deletion of input data on a Niagara VFX module. Description is empty, lowering confidence.
