Let’s dive in!

What is n8n AI Agent?

An AI Agent in artificial intelligence refers to an autonomous system that can perceive its environment, process information, and take actions to achieve goals.

The n8n AI Agent is a feature within n8n that lets users build such agents directly inside workflows. These agents can:

• Process natural language prompts

• Use tools (like HTTP requests, Google Sheets, APIs)

• Store memory and knowledge base

• Generate structured outputs (JSON, text, summaries)

• Work autonomously without constant supervision

In simple terms, n8n turns AI models like GPT, Gemini, Ollama, and others into “agents” that can interact with your data, apps, and workflows.

Is n8n AI Agent Free and Open Source?

One of the most common questions is:

• Is n8n AI Agent free?

  ✅ Yes, n8n itself is free and open-source. You can self-host and use the AI Agent without cost.

• Is n8n AI Agent open source?

  ✅ Yes, the core platform is open source under the Fair Code License.

• Does n8n have AI Agents?

  ✅ Yes, introduced in recent updates, they integrate with LLMs and external APIs.

For teams or enterprises, n8n also offers a cloud-hosted version with pricing plans,
making it easier to scale without managing servers.

How Does n8n AI Agent Work?

The n8n AI Agent works as a special workflow node. You provide:

1. Prompt or Instruction – e.g., “Summarize this document” or “Check stock prices.”

2. Tools – like HTTP Request, Google Sheets, Web Search, or custom APIs.

3. Memory or Knowledge Base – to remember previous interactions.

4. Output Format – JSON, text, or structured data.

The AI Agent then:

• Reads the prompt

• Decides which tools to use

• Executes actions

• Returns results in the specified format

This process is similar to frameworks like LangChain or MCP, but with the simplicity of n8n’s drag-and-drop workflow builder.

n8n AI Agent Tutorial for Beginners

If you’re just getting started, here’s a step-by-step n8n AI Agent tutorial:

Step 1: Install n8n

• Use Docker, npm, or n8n Cloud.

Step 2: Add the AI Agent Node

• Search for AI Agent in the workflow editor.

Step 3: Connect Your AI Provider

• Use OpenAI, Anthropic, Google Gemini, or Ollama.

• Add API keys inside n8n.

Step 4: Configure Tools

• Example tools:

  • HTTP Request → to fetch data

  • Google Sheets → to read/write spreadsheets

  • Webhook → to interact with external apps

Step 5: Run and Test

• Input: “Get the latest Bitcoin price and store it in Google Sheets.”

• Output: AI Agent fetches the price, formats it, and saves to a sheet.

✅ You’ve built your first n8n AI Agent workflow!

n8n AI Agent Examples

Here are some practical examples of n8n AI Agent:

n8n AI Agent vs Other Frameworks

When comparing n8n AI Agent with frameworks like MCP, LLM Chain, and LangChain, here are the key differences:

• Open Source → All four (n8n AI Agent, MCP, LLM Chain, and LangChain) are open source.

• Visual Workflow → Only n8n AI Agent provides a drag-and-drop visual workflow. The others require coding knowledge.

• Beginner Friendly → n8n AI Agent is the most beginner-friendly, while MCP, LLM Chain, and LangChain are more technical.

• Supports Memory → All four frameworks support memory, allowing agents to remember context.

• Integration Tools → n8n AI Agent offers 500+ integrations out of the box. MCP and LLM Chain have limited integrations, while LangChain provides a medium range of connectors.

👉 In short, n8n AI Agent is the best option for non-developers and businesses that want both AI + automation in a single platform, while frameworks like LangChain or MCP are better suited for developers who prefer coding-heavy setups.
