If you already ask Claude to write product descriptions or plan your Diwali sale, you can go one step further: let Claude make those changes on your Opmiz website and store directly.

Opmiz has an MCP server. MCP (Model Context Protocol) is an open standard that lets an AI app like Claude use tools in another service. Once you connect Opmiz to Claude, you can ask in plain words to add a page, write and publish a blog post, update a product or change your site's design, and Claude does it in your Opmiz account.

Setting it up takes about five minutes. There is nothing to install and no API key to copy.

What You Need

• A Claude account. Custom connectors work on every Claude plan. On the Free plan you can add one custom connector; paid plans can add more.
• An Opmiz account. If you don't have one yet, start your free trial: 14 days free, no credit card required.
• The Opmiz connector address: https://mcp.opmiz.com/mcp. You'll also find it with a Copy button in Opmiz under Settings, then AI apps.

Do this once, on claude.ai or in the Claude desktop app.

1. Open Customize, then Connectors. On some versions of Claude this is under Settings, then Connectors.
2. Press + Add, then Add custom connector.
3. For the name, type Opmiz. For the server URL, paste https://mcp.opmiz.com/mcp.
4. Claude detects that Opmiz uses a browser sign-in. Leave the OAuth client ID and secret empty: Opmiz doesn't need them.
5. Press Add.

Press Connect next to Opmiz in your list of connectors.

A new browser tab opens on Opmiz. Your password goes to Opmiz only; the AI app never sees it.

1. Sign in to Opmiz, if you aren't already.
2. Under Which businesses?, choose the businesses it may work on. If you have only one, it's ticked for you.
3. Under What it may do, every permission starts ticked. Untick anything you don't want, such as publishing or orders.
4. Press Allow. The tab sends you back to your AI app.

The app can never do more than you can do yourself in the Opmiz dashboard, and tools for anything you unticked simply don't appear.

In a new chat, press the + button at the bottom left of the message box, choose Connectors, and switch on Opmiz. You can switch it off for chats where you don't need it.

Start with something that only reads, to check the connection:

Claude replies with your business name and pages. You're connected.

Once Opmiz is connected on the web, it also works in the Claude apps on your phone and computer, signed in with the same Claude account.

The first time Claude wants to use an Opmiz tool, it asks you. Press Allow to let it go ahead this once, or Allow always to stop being asked for that tool.

A sensible habit: allow the tools that only read (seeing your site, pages and products) always, and keep approving the ones that change things, at least until you're comfortable. Publishing is a separate step anyway: Claude shows you what will go live and waits for your yes.

Using Claude Team or Enterprise

On a Team or Enterprise plan, an Owner adds Opmiz once for the whole organisation, and each person connects their own Opmiz account.

1. The Owner opens Organization settings, then Connectors, presses Add, chooses Custom, then Web, and enters the name Opmiz and the address https://mcp.opmiz.com/mcp.
2. Each member opens Customize, then Connectors, finds Opmiz and presses Connect, then signs in to Opmiz as in step 2.

Each person's Opmiz role still applies, so a teammate who can only edit content in the dashboard can only edit content through Claude too.

Using Claude Code

If you or your developer use Claude Code, the Opmiz plugin adds the connection along with instructions that help Claude build and edit sites well:

claude plugin marketplace add opmiz-wbos/opmiz-plugin

claude plugin install opmiz@opmiz

Or add only the connection:

claude mcp add --transport http opmiz https://mcp.opmiz.com/mcp

Then run /mcp inside Claude Code and sign in to Opmiz in the browser. Claude Code can also send files, like a spreadsheet of products or a folder of photos, straight to Opmiz.

What to Ask Claude

Talk to Claude the way you'd brief a helpful assistant. A few examples:

Claude reads your site before it changes anything, makes the change in your draft, and can take screenshots to check its own work on desktop and mobile.

How Your Site Stays Safe

Connecting an AI app doesn't hand over your live website.

• Design changes go to your draft. Your customers see nothing until the site is published, and publishing waits for your yes.
• Every change is recorded. Open Settings, then AI apps in Opmiz to see which app changed what, and undo it.
• You can cut it off at any time. Remove the app from AI apps and its access ends at once.
• Some things change the live shop straight away, like product prices, stock, page settings and business details, so the assistant shows you a preview and asks before saving those.

If Something Doesn't Work

• Claude says it has no Opmiz tools. Check that Opmiz is switched on under +, then Connectors in this chat.
• Some tools are missing, like products or orders. Either the permission was unticked when you connected, or you connected before 25 October 2026, when the product, order and content-field permissions were added. Remove Opmiz in Settings, then AI apps in Opmiz, then connect again from Claude.
• You can't add a second custom connector. The Claude Free plan allows one. Remove one you no longer use, or move to a paid Claude plan.
• Claude says your plan doesn't include something. Some features, like delivery fees or bulk uploads, need a particular Opmiz plan. Compare them on the pricing page.
• A change "conflicts" with another one. Someone, or another app, edited the site at the same time. Ask Claude to read the site again and retry.
