Frequently asked questions
Can I change the URL of a QR code after it has been printed?
Yes, if it is a dynamic QR code. Use the update_qrcode tool and provide the new destination URL. The physical code remains the same but the user will be redirected to the new link.
How do I see where people are scanning my codes from?
Run the get_analytics_location query with your QR Code ID. It returns scan data aggregated by country and city, allowing you to track geographic engagement.
Is it possible to list all the tags I'm using for organization?
Absolutely. Use the list_tags query. The agent will retrieve all tags used for categorization, helping you filter and find specific QR codes more easily.
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.
