Frequently asked questions
Can I scrape any web page and extract structured data?
Yes. The web scraping tool uses AI to extract structured data from any URL. Specify what data you want to extract and the tool returns it in a structured format.
Can I generate SQL queries from natural language?
Yes. The text-to-SQL tool converts natural language descriptions into SQL queries. Provide your schema and a plain English question to get the corresponding SQL.
How does JigsawStack authentication work?
JigsawStack uses a custom x-api-key header (not Bearer) for all requests to api.jigsawstack.com/v1.
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.
