Set up the StoreHero MCP in ChatGPT

Last updated: May 25, 2026

The StoreHero MCP lets you ask margin, sales, and ad performance questions directly in ChatGPT — using your real StoreHero data, not platform-reported metrics. Setup takes about three minutes.

This guide walks you through the install, what to try first, and a few things worth knowing once you're up and running.

Before you start

You'll need:

  • An active StoreHero account with full permissions or admin access and at least one store connected

  • A ChatGPT account (chatgpt.com) on Plus, Pro, Business, or Enterprise/Edu — custom MCP connectors are not available on Free

  • To be signed into StoreHero in another browser tab — this matters for the authentication step

If you manage multiple stores under one StoreHero login (common for agencies), the MCP will automatically have access to all of them once connected.

A note on Business and Enterprise/Edu plans: only a workspace admin or owner can enable Developer Mode, and on Enterprise/Edu they can scope access to specific users via role-based permissions. If the toggle in Step 1 is missing, talk to your workspace admin.

Step 1 — Enable Developer Mode in ChatGPT

Go to chatgpt.com and sign in.

Click your profile icon in the bottom-left of the screen, then select Settings. In the left-hand menu, click Connectors, then scroll to the bottom and click Advanced settings.

Toggle Developer Mode to ON. ChatGPT will show a warning about unverified connectors — confirm to proceed.

A few things to know once Developer Mode is on:

  • ChatGPT's memory is automatically disabled in any chat where a custom connector is in use. This is by design — it keeps the MCP server from getting access to context from your other chats.

  • Custom connectors are not reviewed by OpenAI. You should only add MCP servers from sources you trust. StoreHero is fine; random connectors off the internet are not.

Step 2 — Open Connectors → Create

Back in Settings → Apps, click Create Appat the top of the page.

A dialog will appear asking for the connector details.

Step 3 — Enter the StoreHero connector details

Fill in the fields:

  • Name: StoreHero

  • Description: Optional. "StoreHero margin and performance data" works.

  • MCP Server URL: https://app.storehero.ai/api/mcp

  • Authentication: Select OAuth

Do not select "No authentication" or "API key" — StoreHero uses OAuth so that the connector inherits your existing StoreHero permissions and store access. There's no API key to copy and no OAuth client ID to paste — ChatGPT and StoreHero handle the handshake between them.

Tick the box to confirm you trust the connector, then click Create.

Step 4 — Authenticate with StoreHero

ChatGPT will now prompt you to sign in to StoreHero in a popup. Make sure popups aren't blocked.

If you're already signed into StoreHero (which you should be from the prerequisite step), this is a single confirmation click. You'll be returned to ChatGPT automatically once authentication completes. Alternatively if you're not already signed in you may need to do so first.

The MCP will now have read-only access to every store connected to your StoreHero user account.

Step 5 — Confirm it's working

Start a new chat. Click the + icon in the message bar and enable Developer Mode, then toggle StoreHero on for the conversation. You'll see an orange border around the input field — that's ChatGPT telling you a developer-mode connector is live in this chat.

Now try one of these:

Use StoreHero to give me a sales and profit snapshot for this month vs last year.

Use StoreHero to find my biggest wasted ad spend this week.

ChatGPT will ask you to confirm each tool call the first time it runs them. After that, it pulls live data from your StoreHero account and returns the answer inline.

What to ask next

The two example prompts above are a starting point. We've built a full prompt library covering the most useful workflows — sales and profitability reports, paid ads audits, conversion rate analysis, and customer success workflows.

Each prompt is click-to-copy, ready to paste straight into ChatGPT:

👉 storehero.ai/ai-prompts-for-e-commerce-brands-agencies

The reports we hear about most from new users:

  • Sales & profit snapshot — month-to-date vs last year, with the three things worth investigating next

  • Find Meta Ads waste — catches the gap between Meta-reported ROAS and your real blended CPA

  • Gross margin opportunity score — your business benchmarked against your industry on COGS, fees, returns, and fulfilment, with a dollar opportunity in each

  • New customer acquisition picture — CAC payback, profit LTV, and the products driving your most profitable cohorts

Working with multiple stores

If you have more than one store connected to your StoreHero account, just tell ChatGPT which store you mean in the message:

Use StoreHero to give me a sales snapshot for Store Name this month.

ChatGPT will scope the analysis to that specific store. If you don't specify a store, it will ask which one you want to look at.

Agencies running multiple client accounts can switch between stores naturally in conversation. No need to disconnect and reconnect, and no separate logins per client.

Troubleshooting

A few things that trip people up on the ChatGPT side specifically:

  • No Developer Mode toggle. You're either on Free, or on a Business/Enterprise/Edu plan where the admin hasn't enabled it. Check your plan, then check with your workspace admin.

  • OAuth popup is blocked. Allow popups for chatgpt.com and try again.

  • Connector isn't appearing in chat. Click the + in the message bar and make sure the StoreHero toggle is on. Connectors are per-chat, not global.

  • "Memory unavailable" notice. Expected. Memory is intentionally disabled in any chat where a custom MCP connector is active.
