Printify MCP

An MCP server for running a print-on-demand store from an AI assistant: create products on Printify, price them from their production cost, publish them, push them to every Shopify sales channel, and render ad creative from the product mockups.

Fork of TSavo/printify-mcp, substantially extended. See Differences from upstream.

Why it exists

The Printify API alone gets you about two thirds of a working pipeline. The gaps that this fills, each found by hitting it in production:

• Prices are hand-typed. Printify reports each variant's production cost, but nothing derives a price from it. set_prices does, in margin, markup or fixed mode, rounding upward so rounding never eats the target margin.
• Publishing reaches one channel. Printify publishes to Shopify's Online Store publication and stops. TikTok, Google & YouTube, Pinterest, Shop and POS stay unpublished until something else pushes them. publish_to_sales_channels does that.
• Printify guesses the product type wrong. A flask arrives typed "Mug", a candle as "Home Decor". Downstream channels map their taxonomy from that field. set_product_category derives it from Shopify's own category.
• Ad creative is manual. create_product_carousel and create_product_ads build vertical posts from the product's real mockups.

Install

git clone https://github.com/<you>/printify-mcp.git
cd printify-mcp
npm install
npm run build
cp .env.example .env      # then fill in PRINTIFY_API_KEY

Register it with your MCP client. For Claude Code:

{
  "mcpServers": {
    "printify": {
      "type": "stdio",
      "command": "node",
      "args": ["/absolute/path/to/printify-mcp/dist/index.js"]
    }
  }
}

The server resolves .env from its own package directory, not the working directory, so it works no matter where the host launches it from.

Only PRINTIFY_API_KEY is required. Shopify and Replicate credentials unlock the sales-channel and image-generation tools respectively; without them those tools refuse with setup instructions rather than failing obscurely.

Tools

Shops and catalog — get_printify_status, list_shops, switch_shop, get_blueprints, get_blueprint, get_print_providers, get_variants, get_defaults, set_default

Products — list_products, get_product, create_product, update_product, delete_product, publish_product, unpublish_product, get_product_mockups, upload_image

Pipeline — create_and_publish runs create → price → publish → fan out to sales channels → fix category in one call, reporting each stage separately so a partial failure tells you exactly how far it got.

Pricing — set_prices (margin / markup / fixed, dryRun to preview)

Sales channels (Shopify credentials) — list_sales_channels, publish_to_sales_channels, get_channel_sales, list_channel_products

Categories (Shopify credentials) — suggest_product_category, set_product_category, audit_product_categories

Creative — create_product_carousel (numbered 1080×1920 photo slides), create_product_ads (three vertical video variants; needs ffmpeg on PATH)

Orders — get_orders, get_order, get_orders_by_day, get_orders_by_hour, get_orders_by_month, get_orders_in_range

Webhooks — list_webhooks, create_webhook, delete_webhook

Images (Replicate) — generate_image, generate_and_upload_image

Docs — how_to_use with a topic (pipeline, product_creation, blueprints, print_providers, variants, images, publishing, image_generation) returns the reference an agent should read before guessing.

Notes worth knowing

• Never publish a product twice. Publishing an already-published product creates a second channel listing and orphans the first — no Printify link, still purchasable, unfulfillable. publish_product refuses unless republish is passed.
• external.id is not reliably a Shopify product ID. Immediately after publishing it can carry a printify.me handle. The channel tools wait until it points at the configured store; pass shopifyProductId to skip the lookup.
• Errors are real errors. No tool returns empty or placeholder data to paper over a failed request. A bad API key fails loudly at startup rather than quietly serving fabricated shops.
• Creative is built from product photography and text — no generative model touches it, so the output carries no AI provenance metadata.

Differences from upstream

Added: order history and range queries, cost-based pricing, Shopify sales-channel publishing, channel sales reporting, product-category correction, photo carousels and video ads, tags/key features/sales-channel properties on create, print placement (x/y/scale/angle plus image stacking), duplicate-title guard, and the create_and_publish pipeline.

Fixed: list_products passed (limit, page) into a (page, limit) signature; the products list silently returned an empty page on failure; a rejected API key produced two fake shops and reported success; update_product forwarded camelCase variant keys the API ignores, so price updates reported success and changed nothing; publish_product sent a partial payload where Printify requires all seven flags.

Requirements

Node 18+. ffmpeg on PATH for create_product_ads (the carousel tool does not need it).
