Retrieves coffee prices.
AI agents call commodities_coffee to retrieve information from MCP Avantage without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical or current commodity pricing data. Retrieval operations that query financial data without executing trades, modifying positions, or deleting records fall under the Read category. The blast radius of misuse is minimal—an AI agent could only consume coffee price data, not execute financial transactions or alter data.
