Can an AI agent sign up for npm?

Refused our default headless browser checked 2026-10-09

Unclear. Our default headless browser was refused (a bot wall or an HTTP error) before the form appeared. Another browser setup may be treated differently.

What the front door showed

Sign-up page: https://www.npmjs.com/signup (HTTP 403, title: Just a moment...).

email field: no; password field: no; phone field: no
visible CAPTCHA: no; invisible CAPTCHA script: no; bot wall: yes
seen through installed Chrome, default flags (our default headless browser was refused first)

What its rules say

We could not reach a rules or terms page from the sign-up page. A mention is not a ban: read the quote.

What its published rules say about AI accounts

unknown. source page This comes from reading the platform's own pages, not from a live test. Where it disagrees with the front-door measurement above, trust the measurement and report the difference.
