Shopify Multi-Store MCP

One MCP server. Every Shopify store.

Query, compare, report, and make guarded updates across Shopify stores from Claude, Codex, Cursor, VS Code, and other MCP clients.

Version 1.6.0

This branch adds guided Admin workflows, ShopifyQL charts, schema validation, sample-product cards, resumable bulk exports, and real preview stores with claim links. See feature coverage and acceptance requirements. Full Shopify ChatGPT parity is not yet verified.

See it work

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

Tool	Purpose
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_compare_catalog	Compare products by handle, status, vendor, type, and variants.
shopify_catalog_gap_report	Find products that are missing or have different statuses.
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.”
• “Search every store for products related to protein.”
• “Show unfulfilled orders older than two days, grouped by age.”
• “Find products that are active in one store but missing or draft in another.”
• “Find price differences and duplicate SKUs across these stores.”
• “Compare inventory for SKU A123 and B456 across retail and wholesale.”
• “List unfulfilled orders from the last seven days in three stores.”
• “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.

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.

Add this server to the client's MCP configuration:

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

Add this server to .vscode/mcp.json:

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

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

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.
