[FEATURE] Shopify connector: connect several stores (development stores) at the same time

Same request filed on the Shopify side (the connector is Shopify's setup.shopify.com/mcp): https://community.shopify.dev/t/shopify-connector-for-claude-allow-several-development-stores-at-the-same-time/38283

Hey @oguzhanpisgin I’m building Manager for Shopify, an app for managing Shopify stores with AI. Your nine-store setup and repeated reauthorization problem caught my attention. Would you be open to trying giving it a shot, you can install it and connect claude code directly to it? I can share a short demo of how it handles store connections. It's at https://manager.vikasmaur.com/

Until the connector supports this, the Shopify CLI already handles the multi-store part from Claude Code. It keeps one stored token per store, so switching never revokes anything, and parallel agents can each name their own store.

Why the connector can't do it today. This is from its own tools/list and OAuth metadata, read today:

• switch-shop's description says it "Revokes the current store's access token so the next tool call will prompt authorization for a new store." None of the other tools take a store argument; they all act on "the connected store".
• setup.shopify.com's OAuth metadata has no registration_endpoint and no client_id_metadata_document_supported. So I'd expect adding the same URL a second time in Claude Code under another name to have nothing to register against. I haven't tried that.

Workaround with Shopify CLI store commands (docs):

# once per store; "stores an online access token for later reuse"
shopify store auth --store writer-5.myshopify.com --scopes read_products,write_products
shopify store auth --store writer-6.myshopify.com --scopes read_products,write_products
shopify store auth list            # stores authenticated this way

# any agent, any store, no switching
shopify store execute --store writer-6.myshopify.com --query-file seed.graphql --allow-mutations

• store execute runs an Admin API GraphQL query or mutation. Per the docs, "Mutations are disabled by default. Re-run with --allow-mutations". For larger seeding there's store bulk execute.
• Theme work already takes a store per command: shopify theme push --store writer-5 (the store prefix is enough).
• shopify store list lists the stores in your organization. Putting your nine store domains and their roles (source / CI / writer-N / review) in CLAUDE.md lets each agent pick the right --store.
• These are online tokens. The docs say to re-run store auth "if the stored token is missing, expires, or no longer has the scopes you need." Expect to re-auth now and then, once per store, without affecting the other stores.

I haven't run these against a store myself (no Shopify org on my side). The commands and quotes are from shopify.dev as of 2026-10-04.

Thanks for reaching out, @VikasMaur-2nd, and for the offer. For now I'd like to keep store access within Shopify's own tools and the official connector, so I'll pass on trying a third-party app. I appreciate you taking the time to reply.

Thank you, @sean-park-funda, for the careful write-up, and especially for checking the connector's tools/list and OAuth metadata. It matches what we see. Our theme work already uses a separate key per store, so the gap is data seeding through the Admin API. shopify store auth / store execute looks like a good fit for that; we'll try it on one development store first and post the result here. The connector request still stands, since it would also cover claude.ai, not only the CLI.

A short follow-up to my earlier reply: on checking our setup, we already use shopify store auth / store execute as our per-store access path from Claude Code, and it works for us. One limit we hit: running several of these commands at the same time on one owner login broke that login, so we run them one at a time. So the CLI covers Claude Code for us; the request here still stands for the connector, so that claude.ai (and parallel agents) can work with several stores too.

Hey @oguzhanpisgin ,
That's completely fine with me if you at the moment don't prefer to use my application. But I would just like to tell that my application uses shopify provided tools only (shopify cli, shopify connector, official AI providers like claude code, codex) etc. Everything is offical and shopify provided only. I just consider my application to be a better UI and overall experience to use those tools.

Just wanted to tell you this, rest is ofcoursely your choice. I would also highly encourage you to atleast visit my website, there's a dummy demo of the app in the website itself so as to give you a look and feel of how the application would be.

So yeah, that's it from my side. I would not annoy you any further.
Thanks,
Vikas

Thanks for checking. On the "parallel runs broke the login" limit, I read the CLI source (Shopify/cli main @ 7e4e6ac, packages/store/src/cli/services/store/auth/session-lifecycle.ts). The parts that match what you saw:

• Every store execute loads that store's stored session. If the access token is within 4 minutes of expiresAt, it refreshes it with the stored refresh token. There's no lock around that refresh, so parallel commands near expiry each refresh at the same time.
• If a refresh fails for any reason, the CLI deletes the stored session (clearStoredStoreAppSession), then asks you to re-run store auth. One failed refresh in the batch is enough to log out every command after it.
• Sessions are stored per store (key <client id>::<store>), so a failed refresh on writer-5 only clears writer-5.

Why a refresh fails under concurrency isn't visible in the code. Shopify's docs on expiring offline tokens say the previous refresh token stays usable until the new one is used, so plain reuse shouldn't fail by itself. Two ways to narrow it down:

1. shopify store auth list --json shows expiresAt per store. If it's hours away when the breakage happens, refresh isn't your trigger.
2. Run the parallel batch with --verbose. A failing refresh logs Token refresh failed with HTTP <status>: <body>, which names the cause (for example a 429 or a rejected refresh token).

If it is the refresh, you can keep most of the parallelism:

• Run in parallel across stores, but keep commands for the same store in one queue. Refresh and delete are both per store.
• When a store's expiresAt is close, run that store's commands one at a time until store auth list shows a new expiresAt, then go back to parallel.

I haven't reproduced this; I don't have a Shopify org.
