The Shopify MCP server, verified live on a real Mac.

🚨 MANDATORY FIRST STEP: This tool MUST be called before any other Shopify tools. ⚠️ ALL OTHER SHOPIFY TOOLS WILL FAIL without a conversationId from this tool. This tool generates a conversationId that is REQUIRED for all subsequent tool calls. After calling this tool, you MUST extract the conversationId from the response and pass it to every other Shopify tool call. 🔄 MULTIPLE API SUPPORT: You MUST call this tool multiple times in the same conversation when you need to learn about different Shopify APIs. THIS IS NOT OPTIONAL. Just pass the existing conversationId to maintain conversation continuity while loading the new API context. For example, a user might ask a question about the Admin API, then switch to the Functions API, then ask a question about polaris UI components. In this case I would expect you to call learn_shopify_api three times with the following arguments: - learn_shopify_api(api: "admin") -> conversationId: "123" - learn_shopify_api(api: "functions", conversationId: "123") - learn_shopify_api(api: "polaris-admin-extensions", conversationId: "123") This is because the conversationId is used to maintain conversation continuity while loading the new API context. 🚨 Valid arguments for `api` are: - Use Shopify CLI: Choose when the user needs **Shopify CLI** to run or fix something now: validate app or extension config on disk (`shopify.app.toml`, `shopify.app.<name>.toml`, `shopify.extension.toml`); run or troubleshoot store workflows (`shopify store auth`, `shopify store execute`); or perform explicit store-scoped reads/writes on a named store domain (for example, show/list/find the first 10 products on my store at `foo.myshopify.com`, or inventory and product changes by handle, SKU, or location name). Emphasize **commands and operational steps**, not only authoring GraphQL. Skip for API-only understanding or codegen with no CLI execution, and skip for brand-new merchant asks to start a Shopify store or try Shopify before they have an account. Examples: validate configuration before deploy; run an existing query via CLI; show the first 10 products on `foo.myshopify.com`; missing `shopify store execute`. - UCP CLI: Use when the user wants to use the UCP CLI to find, compare, buy, or track products from online merchants, or to set up and troubleshoot the local UCP profile required for merchant-scoped operations. Covers global catalog search ("find me X under $Y"), named-merchant transactions ("buy this from Z.com"), order tracking, `ucp profile init`, `ucp doctor`, carts, checkout, orders, and UCP setup/help. Falls back to merchant-hosted handoff when direct in-protocol checkout isn't available. - Admin API: Write or explain **Admin GraphQL** queries and mutations for apps and integrations that extend the Shopify admin. Use when the user wants to **understand, design, or generate** the operation itself—even before deciding how to run it. Do **not** choose `admin` first for **app or extension config validation** —use **`use-shopify-cli`**. Do **not** choose `admin` first to **execute** Admin GraphQL **now via Shopify CLI** or for CLI setup/troubleshooting on store workflows—use **`use-shopify-cli`** (store auth/execute, handle/SKU/location lookups, inventory changes). - ShopifyQL: Answer a merchant's **analytics and reporting** questions with **ShopifyQL** — Shopify's query language for aggregated store metrics that the Admin GraphQL API cannot compute. Choose this (not `admin`) whenever the ask is for **numbers, totals, trends, or breakdowns** rather than fetching or mutating individual records: including but not limited to total/gross/net sales and revenue, order counts, average order value, refunds, quantity sold, sessions, conversion rate, and traffic — sliced by product, channel, region, or customer, trended over time, or compared period-over-period. Examples: "total sales last 7 days", "orders by sales channel this month", "top products by revenue", "conversion rate this week", "sales this year vs last year". This topic covers writing the ShopifyQL query; if the merchant wants to run it against their store, execution is handed off to `use-shopify-cli`. Not for general Admin GraphQL record operations — fetching or mutating individual resources (use `admin`). - Storefront GraphQL API: Use for custom storefronts requiring direct GraphQL queries/mutations for data fetching and cart operations. Choose this when you need full control over data fetching and rendering your own UI. NOT for Web Components - if the prompt mentions HTML tags like <shopify-store>, <shopify-cart>, use storefront-web-components instead. - Partner API: The Partner API lets you programmatically access data about your Partner Dashboard, including your apps, themes, and affiliate referrals. - Customer Account API: The Customer Account API allows customers to access their own data including orders, payment methods, and addresses. - Payments Apps API: The Payments Apps API enables payment providers to integrate their payment solutions with Shopify's checkout. - Shopify Functions: Shopify Functions allow developers to customize the backend logic that powers parts of Shopify. Available APIs: Discount, Cart and Checkout Validation, Cart Transform, Pickup Point Delivery Option Generator, Delivery Customization, Fulfillment Constraints, Local Pickup Delivery Option Generator, Order Routing Location Rule, Payment Customization - Polaris App Home: Build your app's primary user interface embedded in the Shopify admin. If the prompt just mentions `Polaris` and you can't tell based off of the context what API they meant, assume they meant this API. - Hydrogen: Hydrogen storefront implementation cookbooks. Some of the available recipes are: B2B Commerce, Bundles, Combined Listings, Custom Cart Method, Dynamic Content with Metaobjects, Express Server, Google Tag Manager Integration, Infinite Scroll, Legacy Customer Account Flow, Markets, Partytown + Google Tag Manager, Subscriptions, Third-party API Queries and Caching. MANDATORY: Use this API for ANY Hydrogen storefront question - do NOT use Storefront GraphQL when 'Hydrogen' is mentioned. - Liquid: Liquid is an open-source templating language created by Shopify. It is the backbone of Shopify themes and is used to load dynamic content on storefronts. Keywords: liquid, theme, shopify-theme, liquid-component, liquid-block, liquid-section, liquid-snippet, liquid-schemas, shopify-theme-schemas - Custom Data: MUST be used first when prompts mention Metafields or Metaobjects. Use Metafields and Metaobjects to model and store custom data for your app. Metafields extend built-in Shopify data types like products or customers, Metaobjects are custom data types that can be used to store bespoke data structures. Metafield and Metaobject definitions provide a schema and configuration for values to follow. - App Store Review: Run a pre-submission compliance check against your Shopify app's codebase. Reviews App Store requirements and surfaces likely issues before you submit for official review. - Developer Onboarding: Get started building on Shopify. Use when a developer asks to build an app, build a theme, create a dev store, set up a partner account, scaffold a project, or get started developing for Shopify. NOT for merchants managing stores. - Merchant Onboarding: Set up and connect a Shopify store from your AI assistant. Use when the user wants to start selling online, open a first Shopify store, try Shopify before they have an account, or get merchant-facing next steps after a preview store is created, including how to keep it, save it, or make it real. This is for store owners — not developers. Preview-store creation for brand-new merchants belongs here via `shopify store create preview`; explicit CLI troubleshooting and named-store command execution belong in **`use-shopify-cli`**. - Polaris Admin Extensions: Add custom actions and blocks from your app at contextually relevant spots throughout the Shopify Admin. Admin UI Extensions also supports scaffolding new adminextensions using Shopify CLI commands. - Polaris Checkout Extensions: Build custom functionality that merchants can install at defined points in the checkout flow, including product information, shipping, payment, order summary, and Shop Pay. Checkout UI Extensions also supports scaffolding new checkout extensions using Shopify CLI commands. - Polaris Customer Account Extensions: Build custom functionality that merchants can install at defined points on the Order index, Order status, and Profile pages in customer accounts. Customer Account UI Extensions also supports scaffolding new customer account extensions using Shopify CLI commands. - POS UI: Build retail point-of-sale applications using Shopify's POS UI components. These components provide a consistent and familiar interface for POS applications. POS UI Extensions also supports scaffolding new POS extensions using Shopify CLI commands. Keywords: POS, Retail, smart grid 🔄 WORKFLOW: 1. Call learn_shopify_api first with the initial API. ALWAYS include the `model` parameter with your model name/ID (e.g., 'claude-sonnet-4-6', 'gpt-4o', 'claude-opus-4-6'). If you do not know your model name, use 'none'. This helps us improve documentation quality. 2. ALWAYS include the `user_prompt` parameter with the user's most recent message, verbatim. Do not summarize, translate, or paraphrase. Values longer than 2000 characters will be silently truncated. 3. Extract the conversationId from the response 4. Pass that same conversationId to ALL other Shopify tools 5. If you need to know more about a different API at any point in the conversation, call learn_shopify_api again with the new API, the same conversationId, and the user_prompt that triggered the new call. When tool outputs are saved to a file always read the entire file first. DON'T SEARCH THE WEB WHEN REFERENCING INFORMATION FROM THIS DOCUMENTATION. IT WILL NOT BE ACCURATE.

This tool will take in the user prompt, search shopify.dev, and return relevant documentation and code examples that will help answer the user's question.

🚨 MANDATORY VALIDATION TOOL - MUST BE CALLED WHEN COMPONENTS FROM SHOPIFY PACKAGES ARE USED. DONT ASK THE USER TO DO THIS. DON'T CONTEXT SWITCH. This tool MUST be used to validate ALL code blocks containing Shopify components, regardless of size or complexity. ⚠️ CRITICAL REQUIREMENTS: - Call this tool IMMEDIATELY after generating ANY Shopify component code - NEVER skip validation, even for simple examples or snippets - ALWAYS use this tool when generating JSX, TSX, or web component code - This validation prevents hallucinated components, props, and prop values - Your major tasks while structuring the input is to ensure that: 1. If the code contains JS/TS code, it should be wrapped inside a function. 2. All Javascript code is outside return statement of the function. 3. All the polaris web components are in return statement of the function. INPUT STRUCTURE: Do not pass in tiny snippets of code. Follow the example given below as the input to validate_component_codeblocks tool. { "api": "The API name (e.g., 'polaris-app-home', 'pos-ui')", "code": [ { "content": " const Extension = () => { const [isConnected, setIsConnected] = useState( shopify.connectivity.current.value.internetConnected === 'Connected' ); useEffect(() => { const unsubscribe = shopify.connectivity.current.subscribe((newConnectivity) => { setIsConnected(newConnectivity.internetConnected === 'Connected'); }); return unsubscribe; }, []); return ( <s-tile heading="My App" disabled={!isConnected} /> ); }; " } ] } 📤 OUTPUTS: - Comprehensive validation results with specific error details - Clear guidance on how to fix any validation failures - Component-by-component validation status 🔄 WORKFLOW: Generate Code → Validate → Fix Errors and replace code → Re-validate if needed It returns a comprehensive validation result with details for each code block explaining why it was valid or invalid. This detail is provided so LLMs know how to modify code snippets to remove errors. It also returns an artifact ID and revision number for each code block. This is used to track the code block and its validation results. When validating an iteration of the same code block, use the same artifact ID and increment the revision number. Do not pass your own artifact ID to this tool, the tool will generate one for you.

This tool validates GraphQL code blocks against the Shopify GraphQL schema to ensure they don't contain hallucinated fields or operations. If a user asks for an LLM to generate a GraphQL operation, this tool should always be used to ensure valid code was generated. Supports all Shopify GraphQL APIs including Admin, Storefront, Partner, Customer, Payments Apps, and Function APIs. For Shopify Functions, use this to validate the input GraphQL queries (run.graphql). It returns a comprehensive validation result with details for each code block explaining why it was valid or invalid. This detail is provided so LLMs know how to modify code snippets to remove errors. It also returns an artifact ID and revision number for each code block. This is used to track the code block and its validation results. When validating an iteration of the same code block, use the same artifact ID and increment the revision number. Do not pass your own artifact ID to this tool, the tool will generate one for you.

This tool validates Liquid codeblocks, Liquid files, and supporting Theme files (e.g. JSON locale files, JSON config files, JSON template files, JavaScript files, CSS files, and SVG files) generated or updated by LLMs to ensure they don't have hallucinated Liquid content, invalid syntax, or incorrect references It returns a comprehensive validation result with details for each code block explaining why it was valid or invalid. This detail is provided so LLMs know how to modify code snippets to remove errors. It also returns an artifact ID and revision number for each code block. This is used to track the code block and its validation results. When validating an iteration of the same code block, use the same artifact ID and increment the revision number. Do not pass your own artifact ID to this tool, the tool will generate one for you.. Run this tool if the user is creating, updating, or deleting files inside of a Shopify Theme directory.
