Frequently asked questions
What is Nutri-Score?
Nutri-Score is a front-of-pack nutrition label that rates food products from A (healthiest) to E (least healthy). It's widely used across Europe and helps consumers make informed dietary choices at a glance.
What is the NOVA classification?
The NOVA classification assigns a score from 1 to 4 depending on how much a food is processed. 1 means unprocessed/minimally processed foods, while 4 indicates ultra-processed food and drink products.
Is the allergen data reliable?
The allergen data is derived from product labels uploaded by contributors. While extensive, you should always double-check physical packaging for severe allergies as formulations can change.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
