What it can do

  • Build workflows and AI agents with a large integration library
  • MCP server trigger and MCP client, human approval for tool calls
  • Code steps (JS/Python), webhooks, and API control of n8n itself
  • Hosted and self-hosted options

What it can't do / limits

  • You must design and maintain the workflows; it is not an investor app out of the box
  • Cloud Starter is limited to 1 shared project and 5 concurrent executions
  • Hosted plan data is stored in the EU (Frankfurt) per the pricing FAQ
  • Overage behavior: workflows keep running, but overage charges may apply if you do not upgrade
