n8n Agents The n8n AI Agent node ( @n8n/n8n-nodes-langchain.agent ) is a multi-turn LLM driver with sub-nodes for the model, memory, tools, and an optional output parser. This skill is the deep guide to designing agents and the LangChain family around them. For the high-level "where an agent fits in a workflow" picture, see n8n-workflow-patterns ai_agent_workflow.md — this skill goes one level down into how to build it well . For node-type formats: in workflow JSON the LangChain nodes use the long @n8n/n8n-nodes-langchain.* form ( .agent , .lmChatOpenAi , .memoryBufferWindow , .outputParserStructured , .toolWorkflow , .toolHttpRequest , .toolCode ). When you call get_node / validate_node , use the short form ( nodes-langchain.agent ). See n8n-mcp-tools-expert for the format rules. Pick the right node first Reaching for an Agent when the task is one-shot classification or extraction is the most common over-build.
