Overview

AI-generated overview

Lets an assistant manage a Shopify store through the Admin GraphQL API, including products, orders, inventory, and optional AI image generation via ComfyUI.

What you can do
Wraps the Shopify Admin GraphQL API in tools for products, variants, collections, metafields, metaobjects, draft orders, fulfillment, webhooks, customers, and ShopifyQL analytics. Write tools create, update, and delete store data, and fulfillment tools can mark orders shipped and notify customers. When a ComfyUI URL is configured, bridge tools generate product images and can create or update products with them in one call.
When to use it
Use it when an assistant should read or change a Shopify store directly, for example bulk product edits, inventory updates, draft orders, fulfillment, or running ShopifyQL reports. The ComfyUI bridge is worth adding only if you also run ComfyUI and want generated product imagery attached automatically.
Requirements
Runs locally as an npm package (Node 20+) over stdio or streamable HTTP. Requires SHOPIFY_STORE and the secret SHOPIFY_ACCESS_TOKEN (a shpat_ Admin API token with the needed scopes); SHOPIFY_API_VERSION is optional. The ComfyUI bridge tools need COMFYUI_URL, and optionally COMFYUI_PUBLIC_URL and COMFYUI_DEFAULT_CKPT. Network access to Shopify and, for the bridge, to ComfyUI.
Before you install
The Admin API token grants write access to store data: tools create, update, and delete products, variants, collections, metafields, metaobjects, draft orders, and webhooks, and can complete draft orders and create fulfillments that notify customers. Keep SHOPIFY_ACCESS_TOKEN secret and scope it narrowly. Webhook tools register external callback URLs. Bridge tools send prompts and images to the configured ComfyUI instance, and Shopify fetches generated images from the public URL.

Installation

In SourceWeft

  1. Open Shopify Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

The pitch

Every other Shopify MCP is a plain Admin API wrapper. This one pairs with @miller-joe/comfyui-mcp so you can say things like:

"Create a product called 'Nebula Dreamer'. Generate a cosmic abstract image for it, description matching the vibe, tagged astrology, status draft."

Claude then runs ComfyUI, gets an image back, creates the Shopify product, and attaches the image, all in one call.

Install

bash
# npx, no installnpx @miller-joe/shopify-mcp \  --shopify-store your-store.myshopify.com \  --shopify-access-token shpat_xxx
# Dockerdocker run -p 9110:9110 \  -e SHOPIFY_STORE=your-store.myshopify.com \  -e SHOPIFY_ACCESS_TOKEN=shpat_xxx \  -e COMFYUI_URL=http://comfyui:8188 \  ghcr.io/miller-joe/shopify-mcp:latest

Connect an MCP client

bash
claude mcp add --transport http shopify http://localhost:9110/mcp

Or point your MCP gateway at the Streamable HTTP endpoint.

Transports

The server speaks streamable HTTP by default (great for Claude Code, MetaMCP, raw fetch). Pass --stdio (or set MCP_TRANSPORT=stdio) to switch into stdio mode, which is what stdio-first clients like Claude Desktop and the MCP Inspector expect:

json
// claude_desktop_config.json{  "mcpServers": {    "shopify": {      "command": "npx",      "args": ["-y", "@miller-joe/shopify-mcp", "--stdio"],      "env": {        "SHOPIFY_STORE": "my-store.myshopify.com",        "SHOPIFY_ACCESS_TOKEN": "shpat_…"      }    }  }}

Getting a Shopify access token

Easy path, existing dev store: Shopify Admin → Apps → Develop apps → Create custom app → enable relevant Admin API scopes (write_products, read_orders, write_inventory, read_customers) → install → copy the admin API access token (starts with shpat_).

For new apps (post-Jan 2026): legacy custom-app tokens are deprecated for freshly-created apps. Use the Dev Dashboard token-exchange flow once to obtain a working token, then supply it here. Multi-tenant OAuth is on the roadmap.

generate_product_imageGenerate an image and attach it to an existing product.
refine_product_imageRun img2img on a product's featured image (or an explicit URL) and attach the refined result. Tune denoise (0–1) for how far the result drifts from the source.
bulk_regenerate_imagesFor all products matching a query, run the generator with a templated prompt and attach fresh images.

Template placeholders for bulk_regenerate_images: {title}, {handle}.

Example: the whole pitch in one call

Claude, use generate_and_create_product:  prompt: "minimalist sunset mountain silhouette, warm gradient, vector style"  title: "Mountain Sunset Poster"  status: DRAFT  tags: ["posters", "nature", "minimalist"]

ComfyUI generates the image, Shopify creates the product with the image attached, and you get the product ID and image URL back. One prompt, one call, real listing.

Bridge tools call ComfyUI directly over HTTP, get an image URL, and pass it to Shopify's productCreateMedia mutation. Shopify fetches and hosts the image on its CDN.
