WhizzyCommerce MCP server

WhizzyCommerce MCP

Run your online shop from Claude: orders, prices, sales, catalogue, translations and design, with nothing changing until you confirm.

WhizzyCommerce is an ecommerce platform that is free until you sell. Its remote MCP server lets Claude, ChatGPT or any MCP client read the shop and propose changes in plain language.

This repository holds the documentation for the connector and its plugin manifests for Claude and ChatGPT. The server is hosted by WhizzyCommerce; there is nothing to run.

How it works

• Reads are direct. Orders, products, customers, sales, stock, settings.
• Writes are proposals. A tool that would change the shop returns a preview of every row before and after, plus a confirmation link. Only the merchant, signed in to the WhizzyCommerce dashboard, can apply it.
• Every change leaves a receipt. It lands in the shop's change log with who proposed it and who confirmed it, and most changes can be undone from there. An email that has been sent, or money that has left, cannot.
• Design edits are drafts. Theme changes never touch the live shop until the merchant publishes them.
• Scoped access. Out of the box a connection can only propose price changes and sales. The merchant widens that, or picks a named agent: Analyst (reports only), Shopkeeper (orders, catalogue, reports), Merchandiser (prices, catalogue, reports) or Front desk (customers, orders, reports). None of them includes refunds.

Connect

One address for every shop: when you sign in, you pick the shop the connection is for. Each shop also has its own address, https://app.whizzycommerce.com/mcp/, on the shop's AI screen in the dashboard.

claude.ai

1. Settings, Connectors, Add custom connector.
2. Paste the address and name it whizzy-merchant.
3. Sign in to WhizzyCommerce, pick the shop and allow the connection.

Custom connectors need a Claude plan that allows them; that plan pays for the thinking.
