WHAT IT DOES

What list_niagara_data_interface_functions does on Unreal-MCP

AI agents call list_niagara_data_interface_functions to retrieve information from Unreal-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_niagara_data_interface_functions is rated Low

The tool lists (retrieves) available Niagara data interface functions—a read-only operation with no side effects. Despite the empty description reducing confidence slightly, the naming convention clearly indicates data retrieval. In the Unreal editor context, this is analogous to querying available API functions, which is a safe informational lookup.

From the tool's definition Tool name 'list_niagara_data_interface_functions' uses the verb 'list', which indicates retrieval of information without modification. The context describes a server controlling Unreal Engine 5 editor, and listing functions is a query operation.
