Terminal demonstration of a multi-store Shopify health check and product search

The demonstration uses sample stores and sample data. The server keeps each real store credential separate.

Quick start

Install the server, connect your stores, and run the health check:

npm install --global shopify-multi-store-mcp-server
shopify-multi-store setup
shopify-multi-store doctor

Claude Code users can add the server with one command:

claude mcp add shopify-multi-store -- npx -y shopify-multi-store-mcp-server start

Each store gets a permanent alias and a separate secure credential. Every store operation requires that alias.

What you get

Capability	Result
Multiple active stores	Keep every Shopify store available in one AI conversation.
Cross-store reports	Search products, compare catalogs, find stock gaps, and report fulfillment SLA breaches.
Parallel GraphQL	Run one read-only query across up to ten stores.
Guarded mutations	Target one store and pass an explicit confirmation for each update.
Secure credentials	Use macOS Keychain, Windows Credential Manager, or Linux Secret Service.
Portable skills	Guide Claude, Codex, Cursor, and other compatible agents.

This server and Shopify Dev MCP

The two servers solve different problems. Use both when an agent needs Shopify reference material and access to your stores.

Capability	Shopify Multi-Store MCP	Shopify Dev MCP
Primary purpose	Operate connected Shopify Admin stores.	Search Shopify developer resources.
Store data	Read and compare configured stores.	Does not connect to Shopify Admin store data.
Multiple stores	Keep named stores active in one session.	Not designed for store portfolio operations.
Reports	Provide ready-made operations and catalog reports.	Provide developer documentation and API schemas.
Updates	Run guarded mutations against one selected store.	Does not run Admin API updates against your stores.
Authentication	Use separate credentials for each store.	Needs no authentication.

Shopify Dev MCP helps an agent create and examine Shopify code. This server runs the approved operation against the selected store.

Ready-made reports

`shopify_portfolio_snapshot`	Summarize products, orders, customers, currency, plan, and store identity.
`shopify_order_summary`	Summarize order values, discounts, tax, shipping, cancellations, and statuses.
`shopify_customer_growth`	Compare new-customer counts across equal periods.
`shopify_get_product_everywhere`	Find one exact SKU or handle across stores.
`shopify_search_products_many`	Search products across stores with one query.
`shopify_compare_inventory`	Compare inventory quantities for selected SKUs across stores.
`shopify_low_stock_report`	Find low inventory and cross-store transfer opportunities.
`shopify_compare_prices`	Highlight price and compare-at-price differences for exact SKUs.
`shopify_duplicate_sku_report`	Find repeated SKUs inside stores and shared SKUs across stores.
`shopify_list_unfulfilled_orders`	List open fulfillment work across selected stores.
`shopify_fulfillment_sla_report`	Find late unfulfilled orders and show age buckets.

`shopify_catalog_health`	Find missing merchandising, SEO, media, alt text, and inventory data.
`shopify_recent_product_changes`	List products updated during a selected period.
`shopify_compare_collections`	Compare collection content and configuration by handle.
`shopify_store_locations`	Review location, fulfillment, inventory, and address coverage.

Try prompts like these:

“Give me a portfolio snapshot for every connected store.”
“Summarize orders and current order values for the last 30 days. Keep currencies separate.”
“Show low, zero, and negative inventory across retail and wholesale.”
“Show products that are out of stock here but available in another store.”
“Find SKU A123 across every store and compare its status, price, and inventory.”

“Audit catalog health and show the products with missing SEO or media data.”
“Compare the active catalog and featured collections across these stores.”

Connect an AI client

The server works in clients that support local stdio MCP servers. Agent Skills improve tool selection when the client supports them.

Claude Code

Add the MCP server:

claude mcp add shopify-multi-store -- npx -y shopify-multi-store-mcp-server start

Copy the included skill for personal use:

mkdir -p ~/.claude/skills/shopify-multi-store
cp .claude/skills/shopify-multi-store/SKILL.md ~/.claude/skills/shopify-multi-store/SKILL.md

Claude Code also discovers .claude/skills inside this repository.

Claude Desktop and Cursor

Add this server to the client's MCP configuration:

{
  "mcpServers": {
    "shopify-multi-store": {
      "command": "npx",
      "args": ["-y", "shopify-multi-store-mcp-server", "start"]
    }
  }
}

VS Code

Add this server to .vscode/mcp.json:

{
  "servers": {
    "shopify-multi-store": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "shopify-multi-store-mcp-server", "start"]
    }
  }
}

Other LLM clients

Use npx as the command and -y shopify-multi-store-mcp-server start as the arguments.

Copy skills/shopify-multi-store/SKILL.md into the client's skills directory when supported. Clients without skill support still get every MCP tool.

Store authentication

Method	Command	Best fit
Admin API access token	`shopify-multi-store setup`	An existing Shopify admin-created app and token.
Client credentials	`shopify-multi-store oauth`	Stores in the same organization as the app.
Authorization code	`shopify-multi-store oauth`	Standalone app installations.

Authorization code setup uses http://127.0.0.1:3456/oauth/callback. Add it as an allowed redirect URL first.

The default authorization code scopes are read-only. Grant only the Admin API scopes required for the task.

Manage stores

shopify-multi-store list
shopify-multi-store doctor
shopify-multi-store remove store-alias

Import an existing stores.json file

shopify-multi-store import /absolute/path/to/stores.json

The import copies credentials into the operating system credential store and preserves configured stores. Delete the old credential file after checking the import.

MCP tools

Tool	Action
`shopify_list_stores`	List configured store aliases.
`shopify_get_shop_info`	Read one store's identity.
`shopify_portfolio_snapshot`	Create a cross-store summary.
`shopify_order_summary`	Summarize recent orders and monetary totals by currency.
`shopify_customer_growth`	Compare new-customer counts across equal periods.
`shopify_get_product_everywhere`	Find one exact SKU or handle across stores.
`shopify_search_products_many`	Search products across selected stores.
`shopify_compare_inventory`	Compare SKU inventory.
`shopify_low_stock_report`	Find low inventory and transfer opportunities.
`shopify_compare_prices`	Compare exact SKU prices.
`shopify_duplicate_sku_report`	Find duplicate and shared SKUs.
`shopify_list_unfulfilled_orders`	Report fulfillment work.
`shopify_fulfillment_sla_report`	Report order age and SLA breaches.
`shopify_compare_catalog`	Compare product catalogs.
`shopify_catalog_gap_report`	Find missing products and status differences.
`shopify_catalog_health`	Audit product merchandising and SEO data.
`shopify_recent_product_changes`	List recently updated products.
`shopify_compare_collections`	Compare collections by handle.
`shopify_store_locations`	Review store location coverage.
`shopify_graphql_query`	Run a read-only Admin GraphQL query.
`shopify_graphql_query_many`	Run one query across up to ten stores.
`shopify_graphql_mutation`	Change one store after exact authorization.

Read-only operations can run in parallel. Mutations stay isolated to one selected store.

Shopify companion skills

Install Shopify's official Admin GraphQL and ShopifyQL skills:

shopify-multi-store install-shopify-skills

The command installs both skills for supported agents. Pass --agent <name> to select one agent.

The skills search Shopify documentation and check custom GraphQL operations. ShopifyQL adds sales, revenue, order, conversion, and trend analysis.

This server still controls store selection, credentials, execution, and mutation authorization. Shopify's skill scripts send usage telemetry by default.

Set OPT_OUT_INSTRUMENTATION=true to turn off that telemetry.

This integration uses the official Shopify AI Toolkit. It also reflects useful patterns from Shopify Admin Skills.

Security model

Secrets never enter the main configuration file.

Platform	Credential backend
macOS	Keychain
Windows	Credential Manager
Linux	Secret Service

The configuration stores aliases, domains, API versions, and non-secret OAuth client IDs. Its default path is ~/.config/codex-shopify-multi-store/stores.json.

Set SHOPIFY_MULTI_STORE_CONFIG to use another configuration path.

Never commit access tokens, OAuth client secrets, .env files, or credential-bearing configuration files.
Grant only the Shopify Admin API scopes required for the task.
Confirm the target store before every mutation.
Read SECURITY.md for vulnerability reporting.

Linux credential storage requires a Secret Service provider, such as GNOME Keyring or KWallet.

Other installation options

Run a health check without a global install:

npx -y shopify-multi-store-mcp-server doctor

Install directly from GitHub:

npm install --global github:alex-brecher/shopify-multi-store

Development

git clone https://github.com/alex-brecher/shopify-multi-store.git
cd shopify-multi-store
npm ci
npm test
npm run test:live
npm pack --dry-run

The live test uses configured stores and performs read-only Shopify Admin API calls.
