Make QR codes from Codex CLI: one command, then ask

Codex CLI alone vs Codex CLI with QRFLOW

Codex can write a script that renders a static QR PNG with a library. Not editable after printing, not tracked.

	Codex CLI alone	Codex CLI + QRFLOW
The code you get	A static PNG with your link inside	A dynamic code in your QRFLOW account (static on Free)
Change where it goes after printing	No	Yes, in one sentence
Count scans, by day, country, device	No	Yes
Your own domain in the code	No	Yes, on Premium and Business
Wi-Fi, review, Instagram, PDF and 40 more kinds	Only if you write the format yourself	Ask for the kind by name
Pause, expire, rename, bulk	No	Yes
Where it lives afterwards	In the chat	On your dashboard, tagged with the assistant's name

Once, about a minute

Install the connector

Add it by pasting the address

1
Add the server
In a terminal: codex mcp add qrflow --url https://qrflow.codes/mcp. It lands in ~/.codex/config.toml (shape below).
2
Sign in
codex mcp login qrflow. Your browser opens a QRFLOW page: sign in and press Allow. Codex registers itself and uses a local callback, so the consent screen says it is returning to your own computer.
3
Or use a key instead of signing in
On the Business plan, set bearer_token_env_var = "QRFLOW_KEY" on the server entry and export QRFLOW_KEY in your shell.

Then

1
Ask mid-task
Type /mcp in the Codex TUI to see qrflow and its tools, then: "make a QR code for the preview URL and save the PNG to public/qr.png".

The app screens above are simplified drawings, not screenshots; labels follow each app's own and can move between versions. The QRFLOW consent screen is the real one.

The address to paste

https://qrflow.codes/mcp

Or as JSON, for clients that take a config file

[mcp_servers.qrflow]
url = "https://qrflow.codes/mcp"

Codex treats QRFLOW like any other tool and shows each call before it runs. Because it can also write files, "save the PNG next to the README" works in one go.

Copy and paste

Say this

“Make a QR code for the staging launch page and save the PNG to public/qr-launch.png.”

“List my QR codes and re-point the launch one at the new landing page.”

“Make 30 codes for the seat numbers in seats.csv and write a CSV of seat, short_url.”

“How many scans did the launch code get in the last 7 days?”

Any kind works by name. Popular ones: Link, PDF.

What it cannot do

Add a logo to a code. Logos are added in the QRFLOW dashboard; the assistant's image then includes it.
Make a dynamic code on the Free plan. Free makes static codes (the content is inside the picture); Premium makes dynamic ones you can change later.
See anything outside your QRFLOW account, or act without you: you press Allow once, and deleting a code asks first.
Move money. A Venmo or PayPal code only opens a link you gave it.

Plans

What the assistant can do for you	Free	Premium	Business
Static codes (Wi-Fi, contact card, one-off links)	Yes	Yes	Yes
Dynamic codes: change the destination after printing	No	Yes	Yes
Scan analytics by day, country, device	No	Yes	Yes
Your own link domain (go.yourbrand.com)	No	1	5, chosen per code
Bulk: many codes in one ask	No	500/month	10,000/month
Team	1	1	5 people
Price	$0	$4/month	$29/month

The connector is free. Dynamic codes, analytics and your domain are Premium.

Questions

Can Codex make a QR code for free?

Yes. Codex alone can draw a static QR code, and with the QRFLOW connector the Free plan makes static codes too. A code you can change after printing, name on your domain and track needs QRFLOW Premium ($4 a month).

Is the code safe to print?

Yes. QRFLOW only accepts web, mail, phone, SMS, map and a few app links; a javascript: or data: link is refused. The picture is the same standard QR any phone camera reads.

Can it change a code that is already printed?

If the code is dynamic (Premium or Business), yes: say where it should go now and the printed code follows. A static code cannot change; ask for a new one.

What does the assistant see in my account?

Your codes, their scan numbers and your link domains, and only after you press Allow on a QRFLOW page. It never sees your password. Disconnect any time from Account › Connected apps on qrflow.codes.

Does it work on my phone?

Once connected, yes: connectors follow your Codex account, so the same QRFLOW connection works in the mobile app.

How do I tell which codes an assistant made?

Every code shows its maker on the dashboard: a small "Codex" badge next to the type, the way Canva codes show "Canva".

Where is the config?

~/.codex/config.toml, a [mcp_servers.qrflow] table with url. The same file serves the Codex IDE extensions.
