What Do You Need to Run an AI Agent? (Setup Requirements)

TL;DR: Most cloud AI agents need only an account and a few app connections (no coding). Developer agents usually need an API key, a terminal, and sometimes Docker or a VPS for 24/7 use. The honest answer depends on where it runs — so figure that out first.

The 5 things every AI agent needs

1. A way to run it — a cloud account, your computer, or a server (VPS).
2. A model — many cloud agents include one; developer tools often need your own API key.
3. Connections — the apps it acts on (Gmail, Slack, Notion) via login/OAuth.
4. Instructions — what you want it to do.
5. Permissions — what it's allowed to touch and whether it asks before acting.

Cloud agents (easiest — no coding)

Tools like Lindy or Zapier Agents just need an account and app connections. No API key, no terminal, no server. Best for beginners and business users.

Developer agents (more control)

Tools like Claude Code or Aider typically need a terminal, a code project, and an API key. Cursor runs as a desktop app. More power, more setup.

Running 24/7

If you want an agent working while your computer is off, you need a cloud platform or a VPS. Open-source tools like n8n are commonly self-hosted for always-on automation.
