WHAT IT DOES

What apply_and_save_niagara_scratch_pad does on Unreal-MCP

AI agents use apply_and_save_niagara_scratch_pad 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 apply_and_save_niagara_scratch_pad is rated Medium

This tool modifies Niagara VFX assets by applying edits from a scratch pad and persisting them to disk. While 'save' suggests persistence, the operation is reversible (assets can be reverted, re-edited, or deleted), making it Write rather than Destructive. Severity is medium because unintended modifications to VFX assets could require rework but don't cause permanent data loss or external side effects.

From the tool's definition Tool name contains 'apply_and_save', description states 'Apply & Save button' - both indicate creation/modification of asset data. Affects Niagara VFX scratch pad modules which are reversible edits.
