Frequently asked questions
Can my agent fetch the latest news from Hacker News without an API key?
Yes. This server uses the public Hacker News API, which does not require authentication. You can start exploring stories and comments immediately after subscribing.
How do I read comments for a specific HN story via chat?
Use the 'get_item' tool. Provide the story's numeric ID. The agent will retrieve the detailed contents including all top-level comments, converted cleanly from HTML to Markdown for easy reading.
Can I see the most recent submissions instead of just the top stories?
Absolutely. Use the 'new_stories' tool. This retrieves the most recently submitted stories chronologically, allowing you to track cutting-edge updates and launches in real-time.
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.
