Search the USDA FoodData Central database for foods. Returns nutrition information per 100g serving.
AI agents call search_food to retrieve information from Food Tracker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The search_food tool retrieves and returns nutritional data from a public database without creating, modifying, deleting, or executing any operations. It is purely informational with no capability to alter data or trigger external actions. Low severity because misuse poses minimal risk—an agent cannot harm the user or system by searching food data.
From the tool's definition Tool description states it 'Search[es] the USDA FoodData Central database for foods' and 'Returns nutrition information per 100g serving.' This is a read-only query operation with no side effects.
