AI API for food search by barcode, brand, ingredients

# MCP server on n8n for product lookup by barcode and ingredients via Chomp API

This automation template transforms the external Chomp Food Database API into an MCP-compatible interface for AI agents. It enables agents to perform precise queries—by barcode, name, brand, or ingredients—with automatic parameter extraction from natural language input.

## Who it´s for
- AI agent developers integrating third-party food databases.
- Nutrition tech companies using AI for dietary analysis.
- Allergen tracking and diet management applications.
- Automated shopping assistants based on personal dietary preferences.

## What the automation does
- Receives requests from AI agents via an MCP server using $fromAI() expressions.
- Extracts parameters such as barcode, name, brand, ingredients, keywords, and filters (e.g., no tree nuts).
- Makes HTTP calls to the Chomp API at chompthis.com.
- Returns structured product data back to the AI agent for user-facing responses.
- Supports four operations: barcode lookup, name search, branded food filtering, and ingredient search.

## What´s included
- Ready-to-use n8n workflow with request handling logic.
- Trigger logic for mcp_server_request and ai_tool_call events.
- Integrations with Chomp Food Database API and external AI agents (e.g., Claude, ChatGPT).
- Basic text instructions for deployment and adaptation.

## Requirements for setup
- Active n8n instance with workflow execution capabilities.
- LangChain-compatible MCP server access.
- Valid API key for Chomp Food Database.
- Configured AI agent capable of tool calling via MCP.

## Benefits and outcomes
- Accelerates integration of AI agents with external food databases.
- Enables smart nutrition assistants without manual label parsing.
- Lowers entry barrier for AI-powered food-tech applications.
- Ensures data accuracy through authoritative Chomp database.
- Extends AI functionality with real-time external lookups.
