Connect ChatGPT

Updated 2026-10-17

Only a remote (hosted) server works. ChatGPT cannot start a local npx process.

Steps

In ChatGPT Settings, turn on Developer mode. The switch is usually under Apps / Connectors → Advanced, and under Security on some accounts.
On the connectors page press Create. Use The Face Analysis as the name, one sentence as the description (for example Face measurement statistics, face type rules and a face shape classifier) and the URL below.
Choose No authentication, tick the trust box and create the connector.
In a new chat, enable the connector from the tools menu.

Check it works

Ask: “Using The Face Analysis, what is the median fWHR across your 102 reference faces?” The answer should be 1.78.

Which plans include Developer mode, and its menu names, change on OpenAI's side. On Business and Enterprise an admin may have to allow custom connectors. None of the tools writes anything; all seven are read-only.
