Connect Second Order

Second Order is the lab’s experiment platform. You use it entirely through Claude or ChatGPT: you describe a study in a chat, and the AI builds, tests and hosts it. See the workflow for how it fits into a project.

  1. Get an invite. Second Order is invite-only, so ask Kit for a sign-up link. Links can only be used once and expire after 7 days.
  2. Create your account. Open the link and create a passkey, which signs you in with your fingerprint, face or device PIN instead of a password.
  3. Add it to Claude or ChatGPT. On claude.ai, go to Settings › Connectors, choose Add custom connector, name it Second Order and paste this URL:
    https://2ndorder.live/mcp
    In ChatGPT, add the same URL as a custom connector in its settings.
  4. Sign in. Click Connect, sign in with your passkey and allow access. To check it worked, ask Claude/ChatGPT “which Second Order account am I signed in as?”
