Frequently asked questions
Can I fetch profile details for any Hashnode user?
Yes! Use the get_user tool with the specific username handle. The agent will return their profile information, bio, and social links.
Does the publishing tool support Markdown formatting?
Absolutely. Both create_post and update_post accept contentMarkdown, allowing you to publish rich technical content with code blocks, headers, and links.
How do I list posts from a specific blog domain?
Use the get_publication_posts tool and provide the host domain (e.g., 'engineering.hashnode.dev' or your custom domain). It will return a list of recent posts from that publication.
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.
