What is n8n?
n8n is a node-based workflow automation platform, source-available under a fair-code license, that connects apps and services through visual workflows and includes an AI Agent node for building LLM-driven automations.
How It Works
n8n lets you build automations by wiring nodes together on a canvas. Each node is a step: a trigger such as a webhook or a schedule, an app action, a data transform, or an AI Agent node that calls an LLM. It is source-available under n8n's Sustainable Use License, a fair-code model that is free to self-host for internal use but restricts resale. n8n can act as both an MCP client and an MCP server. For example, a workflow can start when a form is submitted, enrich the lead, and post a summary to a team channel. In my view, n8n suits deterministic, repeatable pipelines while a Claude agent suits open-ended reasoning tasks, and many builds use both.

AI Agents
Autonomous software programs powered by artificial intelligence that can perceive their environment, make decisions, and take actions to accomplish specific goals.
Webhook
A webhook is an HTTP callback: when something happens in one system, it sends the event data as a POST request to a URL you provide, so you receive updates instead of repeatedly polling for them.
Model Context Protocol (MCP)
Model Context Protocol (MCP) is an open standard, introduced by Anthropic in November 2024, that lets AI applications connect to tools and data sources through one common protocol instead of custom integrations.
