Definition
n8n is one of the leading open-source workflow automation platforms (think Zapier, but self-hostable and code-friendly). The Agent node is n8n's native AI agent execution layer, powered under the hood by LangChain. It accepts a model, tools (any n8n action becomes a tool), memory, and a system prompt, then runs the agentic loop inside the workflow. The node lets non-engineers build agents that are tightly integrated with the rest of their automation: an n8n agent can read from a webhook, query a database, call an LLM, transform the result, and push to Slack, all in one workflow.
When To Use
Use the n8n Agent node when AI is one step in a larger automation workflow. Skip when the agent itself is the product (use a code-first framework like LangGraph or Pydantic AI for that).
