How to Connect Magento 2 to ChatGPT and Claude (2026)

“Connecting Magento to ChatGPT or Claude” means one of three different things. You can make your store readable so the assistants find and cite it. You can connect your live store to an assistant as a connector, so a shopper can search, build a cart and order in the chat. Or you can connect your Magento code to a coding agent such as Claude Code. Each needs different work. This guide covers all three.

Checked on 7 October 2026. Assistant features and plans change often – check the vendor documentation before you build on a detail here.

The three ways at a glance

Way 1: Make ChatGPT and Claude able to read your store

There is no button that “connects” a store to ChatGPT or Claude. They find stores the way search engines do: their crawlers read your pages. ChatGPT can also read a product feed you send to OpenAI.

1. Allow the search crawlers in robots.txt. OAI-SearchBot decides if you can appear in ChatGPT search. Claude-SearchBot indexes for Claude. ChatGPT-User and Claude-User open a page when a person asks about it. Blocking GPTBot or ClaudeBot only stops training – it does not remove you from answers. Remember: a named group in robots.txt does not inherit your User-agent: * rules, so repeat your Disallow lines. See robots.txt for AI crawlers in Magento 2.
2. Publish Product JSON-LD on the server. With offers.availability as a full URL such as https://schema.org/InStock. Not through Google Tag Manager – most AI crawlers do not run JavaScript. See Product JSON-LD for AI search.
3. Add llms.txt. A short map of your key pages. No AI vendor has promised to read it, but it costs little. See llms.txt.
4. For ChatGPT shopping results, send an ACP product feed. Apply at chatgpt.com/merchants. As of September 2026 there is a waitlist, and shopping is live for US users. A feed is not required – OpenAI says a store can also appear through crawling – but it gives you control over price and stock. See ChatGPT Shopping for Magento 2.

Check the result with the free AEO scan or bin/magento angeo:aeo:audit.

Way 2: Connect your store to ChatGPT or Claude as a connector

A connector uses the Model Context Protocol (MCP). Your store runs an MCP server with tools such as search_products, add_to_cart and place_order. The assistant calls those tools with live data. Claude and ChatGPT both support remote MCP servers.

Step 1: Install an MCP server on Magento

composer require angeo/module-mcp-server angeo/module-mcp-checkout
bin/magento module:enable Angeo_McpServer Angeo_McpCheckout
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento cache:flush

Start with the read-only server only. Add mcp-checkout when you want orders, and set its limits first: maximum order value, item count and a rate limit. Under Agent presentation, set “Store name for agents” to the name your customers use. Check the setup with bin/magento angeo:mcp:tools. Other Magento MCP projects exist – see the comparison of 17 projects.

Step 2: Put an OAuth 2.1 layer in front

Claude and ChatGPT connect to custom connectors through OAuth. With angeo/module-mcp-server, the store’s own /mcp path uses a bearer token and has no OAuth flow, so you cannot paste it into Claude or ChatGPT – the attempt fails with an unclear error. You put an OAuth 2.1 layer in front: it checks the shopper’s token and calls Magento with its own credential. See authentication and exposure. Some other Magento MCP modules build OAuth 2.1 into the module itself – compare them in the MCP server comparison. A bearer token is fine for Claude Code (Way 3).

Step 3a: Add it to Claude

1. Open Settings -> Connectors and click Add custom connector.
2. Name it after the store and paste the OAuth-capable URL.
3. Leave the advanced Client ID and Secret fields empty if your endpoint supports dynamic registration.
4. Complete the consent step. Set read-only tools to “Always allow” so a search does not stop for a click.

Custom connectors work on Free, Pro, Max, Team and Enterprise plans. The free plan allows one custom connector.

Step 3b: Add it to ChatGPT

1. In Settings, turn on Developer Mode (Plus, Pro, Business, Enterprise or Edu; not the free plan).
2. Go to Apps & Connectors -> Add custom app, enter the URL and complete the OAuth flow.
3. In a chat, open the tools menu and switch the app on.

What to expect

The connector wins every question about your store: what you sell, your return policy, shipping to a postcode, the cart. It often loses a cold request that names no shop, such as “find me a grey backpack” – the assistant uses its own product search. A connector is not a discovery channel. It helps people who already know you. Payment never happens in the chat: the order comes back with a payment link to your own gateway. See the MCP checkout documentation and a real order placed by Claude.

Way 3: Connect Magento code to Claude Code

Claude Code is Anthropic’s coding agent in the terminal. It can use MCP servers too, so it can read Magento-specific data while it works on your code.

Developer-side options documented by their projects:

• Magento 2 and Adobe Commerce PhpStorm plugin – exposes MCP tools from the IDE.
• n98-magerun2 – includes an MCP server since version 9.3.0, for CLI and database tasks.
• Adobe Commerce Developer MCP – Adobe’s tooling for Adobe Commerce as a Cloud Service.

Add a server with the claude mcp add command, then check it:

# an HTTP server
claude mcp add --transport http my-store https://shop.example/mcp --header "Authorization: Bearer YOUR_TOKEN"

# a local command (stdio) server
claude mcp add --transport stdio my-tool -- <command> [args]

claude mcp list      # list servers
# inside Claude Code, type /mcp to see connected servers and tools

Use claude mcp add --help for all options, and each project’s README for its exact start command.

Be careful with write access. Developer MCP servers can run CLI commands, edit files and query the database. Point them at a local or staging copy, not production. Treat product descriptions and code comments as data, not instructions – they can carry prompt injection. One project, elgentos magento2-dev-mcp, is marked abandoned and has a published security advisory.

Which one should you do first?

For most stores: Way 1 first. It is the only one that can bring new customers, and it is cheap. Way 2 makes sense when you have customers who would add your store to their assistant, or for internal use – for example merchandisers asking “which in-stock products have no images?”. Way 3 is a developer choice and does not change what shoppers see.

Questions

Can I connect Magento to ChatGPT without coding? For Way 1, mostly yes: free Composer modules handle robots.txt, schema, llms.txt and the feed, and a developer can install them in an afternoon. A store connector (Way 2) needs an OAuth layer, which is real engineering work.

Is there an official Magento app in ChatGPT or Claude? No built-in one. You use crawling, a product feed, or your own MCP connector.

Can a shopper pay inside ChatGPT? Normally not. Since March 2026, purchases that start in ChatGPT finish on the merchant’s own site. With an MCP connector, the order comes back with a payment link.

Is it safe to let an assistant place orders? Only with limits enforced in Magento, not in the prompt: authentication, order value and quantity caps, rate limits, guest checkout only, and a confirmation before every order.

Does it cost anything? The angeo modules are free and MIT-licensed. Discovery in ChatGPT has no fees. Your costs are engineering time and, for a connector, hosting the OAuth layer.
