Every Client Store in One AI - A Multi-store Shopify Connector

A digital agency looks after Shopify stores for itself and for clients. The team uses Claude to update products, check orders, write content and fix themes. But Shopify's own connector works with one store at a time. Every time someone moved to another client, they had to disconnect, reconnect and sign in again, on every computer.

Some jobs it couldn't do at all, and any question across all the stores meant asking the same thing store by store.

One connector for every store. Each tool takes a store name, a list of stores or "all", so the AI works across the whole client list in one conversation. Store logins are kept securely in the cloud, so a store added once is ready on every computer in the team. A new client store is added by sending the merchant a single install link to approve.

We matched every tool in Shopify's own connector, then went further: theme editing with rollback, bulk operations, file uploads, menus, translations, markets, policies and full Admin API access for anything else.

Working on someone else's store needs care. Changes to more than one store, deletes, theme publishes and policy changes all need an explicit confirm, and nothing is sent without it. The live theme is protected, publishing returns the exact call to roll back, and a policy is saved before it's replaced. Tokens and secrets are never logged or returned to the AI.

• Shopify Admin GraphQL API: pinned to a tested API version, with built-in handling of Shopify's query cost limits.
• Model Context Protocol: one server used from Claude Desktop and Claude Code on Windows and Mac.
• AWS: a small install service and an encrypted token store shared by the team.

The team moves between client stores mid-conversation, asks questions across every store at once, and does theme and bulk work that used to mean logging into each admin. Nobody disconnects or reconnects anything.
