Frequently asked questions
Can my AI search for a specific dashboard or data table by keyword?
Yes. Ask the agent to perform an asset search using a natural phrase like 'Q3 revenue report' or 'customer addresses table'. The agent triggers Atlan's semantic asset search, returning linked objects across all connected BI and database sources.
Are custom Atlan Classifications and Tags exposed to the AI?
Yes. The agent can list all organizational classifications configured in Atlan (e.g., Sensitive, Restricted, CCPA). This lets the AI contextualize whether the assets it discovers are safe to be shared globally or subject to governance restrictions.
Can the agent modify or write back metadata to Atlan?
No. This MCP integration focuses strictly on safe discovery and organizational governance retrieval (queries). It guarantees your metadata catalogues remain pristine, acting purely as an active lookup augmentation tool for your agent.
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.
