Frequently asked questions
Can I list all my active surveys using my AI agent?
Yes! Use the list_surveys tool to retrieve a full list of surveys in your Formbricks environment.
How do I check responses for a specific survey?
Simply provide the Survey ID to the list_responses tool. Your agent will fetch all submissions associated with that survey.
Can I delete a survey using this agent?
Yes, use the delete_survey action and provide the unique Survey ID.
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.
