Your own AI coding agent can now work on a store's DataJet scripts and functions. Connect , , , or any other MCP client to DataJet's new MCP server and let it list, read, create, update, validate and debug scripts from your own editor or terminal.

Open , tick and save. The block shows the setup for each client — for Claude Code it's a single command. The first connection opens an approval page in your DataJet admin: pick the permissions, approve, and go back to your editor.

Scripts and functions created by an agent are until you turn them on, exactly like scripts from the AI Assistant.

Seven new Liquid filters make type conversion explicit. Values from CSV files, metafields, webhooks and API responses often arrive as text — now you can turn them into exactly the type you need, without workarounds.

Your dashboard has been redesigned from the ground up to answer one question at a glance:

— the new top strip shows your active scripts, runs and errors from the last 24 hours, what's running right now (live), and your credit usage with a projection of when you'll hit your limit.

— failing scripts now surface themselves. Criticals and warnings across your whole store appear at the top of the dashboard with occurrence counts, deep links to pre-filtered logs, and per-issue dismissal.

✨ — when a script fails, DataJet's AI analyzes the error, your code, and your configuration, then tells you what went wrong in plain language. When the fix is a code change, you get a side-by-side diff you can apply with — and the issue switches to "Monitoring" until a successful run confirms the fix.

— every task now has its own page with an AI-generated description of what it does, statistics, last-run status, performance hints, and its full configuration — no more digging through modals.

— task and function settings render in a clean two-column layout with grouped sections, named product/collection pickers, inline validation, and unsaved-change protection.

— shared variables and secrets moved out of a modal into a dedicated page, including a "used by" column showing which tasks reference each value.

— logs open in a slide-out panel with severity, date, and category filters, live streaming, and one-click export. "View logs" from Needs attention lands you exactly on the errors that matter.

— scripts checkout functions now get automatic plain-language descriptions: a one-liner in the list and a full explanation on the details page.

The Functions Console gets a fifth category: . Write JavaScript that reshapes the cart itself — bundle products together, break bundles apart, or change how lines are presented, with any logic you can express in code.

Open the folder in the Functions Console and click . Pick the family, or to build rules around product and customer tags — think "merge everything tagged into one discounted line". Write a function body that returns transform operations; the starter code documents the exact shapes, and the editor's autocomplete knows your input inside out.

Turn the function on and it runs on — buyers see merged bundles and expanded components in the cart immediately, no checkout required.

The Functions Console gets a fourth category: . Write JavaScript that applies automatic discounts at checkout — any rule you can express in code, from "10% off tagged products" to "amount off orders over a threshold for returning customers".

Open the folder in the Functions Console and click . Pick a family — the same 13 families you know from validations and customizations decide which checkout data your code sees — and write a function body that returns discount operations. The starter code documents the exact shapes, and the editor's autocomplete knows your input inside out.

Turn the function on and the discount is live at checkout immediately. It also shows up on the Shopify admin page like any other automatic discount, and it combines with your existing discounts.

You can now write JavaScript that runs — synchronously, on every order, enforced by Shopify itself. Where scripts react to events after they happen, Functions let you set rules that apply the order is placed.

Head to the new in the app and click . Pick a family — it decides which checkout data your code receives (cart, customer, addresses, tags, selling plans, time and more) — and write a plain JavaScript function body. The editor gives you full autocomplete for your input data, adjustable so values like thresholds can be changed without touching code, and built-in — every save is committed, and you can view diffs and restore any previous version.

A few things worth knowing:

Not sure where to start? We've collected ready-to-use examples — order limits, PO Box blocking, B2B payment rules, free-shipping perks for loyal customers, and more.

The number of simultaneously active functions depends on your plan (Advanced: 1, Pro: 5, DataJet: 25). See the Functions documentation for full details.

Managing many open tasks just got easier.

for quick actions:

— grab any tab and drop it where you want it. Your tab order is remembered, so it's right where you left it next time you open the Developer Console.

Closed a tab by accident? (Alt+Shift+T) brings it back.

The Developer Console just got a lot faster to move around in. Press (Ctrl+Alt+K) — or — anytime to see the full shortcut list right in the editor.

You can now export a script's full log history and have it delivered straight to your inbox — no more scrolling through the log viewer or copying entries by hand.

Open the next to any script and choose , enter the email address to send to, and we'll do the rest in the background.

Switching between scripts in the editor now feels instant and remembers exactly where you left off.
