Frequently asked questions
Can I generate documents from templates through the AI agent?
Yes. Browse available templates, inspect their required fields, and generate documents by providing field values. Output documents are created automatically.
Can I browse available apps and templates?
Yes. List all Knackly apps and their associated templates with field configurations, data types, and validation rules.
What API endpoint does Knackly use?
Knackly uses Bearer authentication against api.knackly.io/v1.
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.
