Frequently asked questions
Can I fetch pre-rendered HTML for my components instead of raw JSON?
Yes! Use the get_html tool. It returns pre-rendered HTML for a specific model and URL, which is perfect for quick inspections or server-side integrations.
Do I need a Private API Key to use this server?
A Public Key is required for all read operations (get_content, query_graphql). However, a Private Key is mandatory for write operations like create_content, update_content, or admin_graphql.
Can I perform administrative tasks like managing Spaces or Models?
Yes, the admin_graphql tool allows you to execute administrative queries and mutations against the Builder Admin API, provided you have supplied a Private API Key.
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.
