list_price_references
AI agents call list_price_references to retrieve information from Fuul MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name strongly suggests retrieving or enumerating price references without modification. Despite the empty description lowering confidence slightly, the naming convention places this clearly in the Read category with low severity, as it poses minimal risk if misused by an agent (returns data only).
