shopify-mcp

MCP server for Shopify. Full Admin GraphQL API tooling plus an AI-driven product creation bridge via ComfyUI image generation.

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 install
npx @miller-joe/shopify-mcp \
  --shopify-store your-store.myshopify.com \
  --shopify-access-token shpat_xxx

# Docker
docker 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.

Configuration

CLI flag	Env var	Default	Notes
`--shopify-store`	`SHOPIFY_STORE`	(required)	`my-store` or `my-store.myshopify.com`
`--shopify-access-token`	`SHOPIFY_ACCESS_TOKEN`	(required)	Admin API token (`shpat_…`)
`--shopify-api-version`	`SHOPIFY_API_VERSION`	`2026-04`	GraphQL Admin API version
`--host`	`MCP_HOST`	`0.0.0.0`	Bind host (HTTP mode only)
`--port`	`MCP_PORT`	`9110`	Bind port (HTTP mode only)
`--stdio`	`MCP_TRANSPORT=stdio`	(unset)	Speak MCP over stdio instead of HTTP. Use when launched as a subprocess by a stdio-first MCP client (Claude Desktop, mcp-inspector).
`--comfyui-url`	`COMFYUI_URL`	(optional)	Enables bridge tools when set
`--comfyui-public-url`	`COMFYUI_PUBLIC_URL`	same as `--comfyui-url`	External URL used for image references passed to Shopify
(no flag)	`COMFYUI_DEFAULT_CKPT`	`sd_xl_base_1.0.safetensors`	Default checkpoint for bridge tools

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:

// 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.

Example: the whole pitch in one call

code

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.
