Frequently asked questions
Can my AI create a new verification application?
Yes. Use create_application with the customer name and email. The agent starts the verification process and returns the application ID.
How do I check document verification results?
Use get_document with the application and document IDs. The agent returns verification status, document type, and any flags.
Can I track the overall verification status?
Yes. get_verification_status returns the current status of any application — pending, approved, or rejected.
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.
