n8n-nodes-ai-agent-langfuse

This is a community node for the n8n workflow automation platform that sends Langfuse tracing and observability data for tool-calling AI agent workflows, including reasoning steps, tool calls and structured output.

Visit website github.com

The node integrates with LangChain's AgentExecutor and ToolCallingAgent inside n8n, automatically sending each agent run's reasoning, tool calls and output to a configured Langfuse instance, whether that is Langfuse Cloud or a self-hosted deployment. Custom metadata such as a session ID, user ID or arbitrary structured JSON can be attached to each trace for later filtering.

It is installed like any other n8n community node, either from the n8n UI's community nodes settings, through a preconfigured Docker setup included in the repository, or by installing the npm package directly into an existing n8n installation.

It is published on npm and written in TypeScript.
