n8n AI Agents

Introduction

n8n is an open-source, low-code workflow automation platform. It uses a visual, node-based system to connect over 400 applications and APIs.

Its AI Agent functionality allows users to build autonomous workflows powered by Large Language Models (LLMs) that can make decisions, interact with apps, and execute complex, multi-step tasks without constant human input.

While standard n8n workflows follow a linear path (Trigger → Action → Action), the AI Agent functionality introduces autonomy.

What is an AI agent?

In n8n, an AI Agent acts as a “brain” within your workflow. Instead of following a strict set of pre-defined steps, an Agent uses a Large Language Model (LLM) to:

• Understand natural language input.
• Reason about the best way to solve a problem.
• Select Tools (such as search, database lookups, or API calls) to gather information.
• Execute complex, multi-step tasks without constant human intervention.

Accessing n8n

n8n is hosted on our Kubernetes/Rancher infrastructure.

Prerequisites

• Account: A valid MetaCentrum account is required.
• Platform: Access via Rancher https://rancher.cloud.e-infra.cz/.
