WHAT IT DOES

What remove_niagara_custom_hlsl_pin does on Unreal-MCP

AI agents call remove_niagara_custom_hlsl_pin 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_custom_hlsl_pin is rated Critical

Removing a pin from a Custom HLSL node destroys that pin's connections and configuration. This action cannot be trivially undone (unless the editor has undo history), and rebuilding the signature alters the node permanently. This fits Destructive as the most applicable category, with medium severity since it affects a single node in an Unreal Engine project rather than broader data loss.

From the tool's definition 'Remove a pin from a Custom HLSL node and rebuild its signature' — removing a pin is an irreversible structural modification that deletes part of the node's configuration
