E-commerce to MCP: Connect Shops to Claude and ChatGPT

TL;DR: AnythingMCP turns your shop and your marketplace accounts into MCP tools for Claude, ChatGPT and Copilot. Thirteen shops and marketplaces have a ready adapter, from Amazon Seller Central and eBay to Kaufland, OTTO and Zalando; install one, authorise it, and ask about orders, stock and returns across all of them in one conversation.

Which shops and marketplaces are supported

† Built from the vendor's published API documentation and not yet exercised against a live seller account.

What each adapter covers differs, and the setup guides list every tool. Two things to know up front: the Shopware 6 adapter uses the Store API, so it reads the storefront catalog (products, categories, cross-sells) but not orders; and WooCommerce, with 49 tools, is the most complete, including refunds, coupons and reports.

Step 1 — Run AnythingMCP

Shop and marketplace APIs are on the internet, so AnythingMCP Cloud is the quickest start. To keep the credentials in-house, self-host it:

mkdir anythingmcp && cd anythingmcp
curl -fsSLo docker-compose.yml \
  https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d   # → http://localhost:3000

Step 2 — Install one connector per channel

Click Install in the table (Cloud) or open Connectors → Store. Marketplaces with OAuth (Amazon, eBay, Etsy, OTTO, Zalando, Mercado Libre) send you to the vendor to authorise; the others ask for an API key or a user and password. Put every channel on the same MCP server and the AI can compare them in one answer.

Step 3 — Keep writes behind a role

Most marketplace adapters only read. The shop systems can also change data: WooCommerce, Magento, BigCommerce and Ecwid can create or update products and orders, OTTO Market can update stock and prices, eBay can update an offer's price. Give the AI a read-only role first and add write tools deliberately.

Step 4 — Connect Claude, ChatGPT or Copilot

• Claude: Customize → Connectors → Add custom connector, paste the MCP server URL (step by step).
• ChatGPT: add the public HTTPS URL as a connector (app) in ChatGPT's settings.
• Claude Code, Cursor, VS Code / Copilot: add the URL with an X-API-Key header.

Example prompts

• "Which orders from yesterday have not shipped yet, on Kaufland and OTTO?"
• "Which products are low on stock in WooCommerce, and how fast did they sell last month?"
• "Summarise this week's returns by reason across all channels."
• "What are the Amazon fees on SKU A-1043 at 24.90 EUR?"
• "Which Etsy reviews this month are below four stars, and what do they say?"
• "Raise the price of offer 1234 on eBay to 39 EUR." (write tool, needs an explicit role)

Security and governance

• Roles decide the tools: an MCP server exposes only the tools its role whitelists.
• Response mapping strips customer addresses, phone numbers or payment details before they reach the model.
• Audit log: every call with input, output, duration and status.
• Credentials are encrypted with AES-256-GCM; OAuth tokens are refreshed automatically.

FAQ

How do I connect my shop to Claude? Install your shop's adapter in AnythingMCP, authorise it, and add your MCP server URL to Claude as a custom connector.

Can I ask about several marketplaces at once? Yes. Put all your channel connectors on one MCP server; the AI calls each and combines the answers.

Can ChatGPT use it too? Yes, as a connector with the public HTTPS URL of your MCP server, for example on AnythingMCP Cloud.

Can the AI change prices, stock or orders? Only through write tools, and only if a role gives it access. Most marketplace adapters only read.

My shop system is not in the list. Can I still connect it? If it has a REST API with an OpenAPI spec, import the spec (OpenAPI to MCP); GraphQL APIs work the same way (GraphQL to MCP).

Does customer data reach the AI provider? Only the fields a tool returns, and response mapping lets you drop personal data before it leaves your AnythingMCP instance.
