Fax from ChatGPT and Codex

Ask ChatGPT or Codex to fax any document to any fax number. Add your pages from your computer or your phone, and check the fax before it goes.

Connect XipFax

In ChatGPT. XipFax is on its way to ChatGPT’s directory. Until it’s there, use Codex, below, or add XipFax by its address where your account allows: go to Plugins, select the plus button, then Add custom MCP server, name it XipFax, enter https://mcp.xipfax.com/mcp under Connection, accept the warning, and select Create as a plugin. Sign in to XipFax with your email: new to XipFax, you make your account as you sign in. Check the account shown, then select Allow.

In Codex. Add XipFax’s plugin:

Your shell

codex plugin marketplace add XipHubHQ/xipfax-plugins
codex plugin add xipfax@xipfax-plugins

Start a new session, and connect XipFax when Codex asks.

Ask

“Fax my signed lease to my landlord.”
“Add pages from my phone to a fax.”
“Has that fax been delivered? I need the confirmation.”
“Where do I fax Form 2848? I live in Ohio.”

Your pages

A PDF at a public link: XipFax fetches it.
In Codex: a PDF or a photo on your computer, made into a PDF first.
On your phone, or attached to the chat: you get a one-time page. Add your pages there, select “Done adding pages”, and say you’re done. The page works once, for 30 minutes. Keep its link to yourself.

Sending

Without a plan: you get a link. Look the fax over there, then send it and pay.
On a plan: choose whether faxes go straight away or come to you first, when you connect or later in Settings › Connected apps.

After it’s sent

Ask how your fax went. Once it’s delivered, you get its confirmation: one page that says who received how many pages, and when.

What XipFax doesn’t do

Fill in forms. Fill in and sign your form first.
Fax numbers outside the United States, its territories and Canada.

Disconnect

In XipFax, go to Settings › Connected apps and select Disconnect. An app stays connected until you disconnect it, or after 30 days unused.
