Shopify Dev MCP

Gives an AI coding assistant Shopify's developer documentation and API schemas while you build apps, themes and extensions.

What it is and why it matters

Shopify Dev MCP is a documentation and schema server for builders. When you ask an AI coding assistant to write a Shopify app, theme change or API query, the assistant normally guesses from whatever it learned in training, which can be out of date. Connected to Shopify Dev MCP, it can look up Shopify's current developer documentation and API schemas first, then write code that matches them.

It is aimed at developers and agencies who build on Shopify, not at merchants who want to chat with their sales data. It does not read or change a live store. Think of it as giving your assistant the official manual, open at the right page.

What it does

  • Searches Shopify developer docs
  • Looks up the GraphQL Admin API schema
  • Helps validate generated code against the schema

Best for

Developers and agencies building Shopify apps and customizations.

How to connect it

  1. Install Node.js, because the server is started with npx on your own machine.
  2. Open the MCP settings of your AI tool (Claude Desktop, Claude Code, Cursor or VS Code).
  3. Add a server that runs the Shopify Dev MCP package, using the exact command shown in Shopify's Dev MCP documentation.
  4. Restart the tool and ask a Shopify development question to confirm the assistant now cites current docs.

Exact commands and addresses change. Use the official documentation for the current steps.

Questions you can ask it

  • Write a GraphQL Admin API query that lists the 10 most recent orders with their line items.
  • Which access scopes does my app need to read inventory levels at each location?
  • Review this Liquid snippet against the current theme documentation and fix any problems.
  • How do I add a metafield definition to products through the API?

What it cannot do

  • It does not connect to your store, so it cannot read orders, products or customers.
  • It cannot deploy changes or publish a theme.
  • It does not replace testing: generated code still has to be run and reviewed.

Staying safe

  • The documentation tools are low risk because they do not touch store data.
  • Do not paste API keys, access tokens or customer data into prompts while developing.
  • Review generated code before running it, especially anything that writes data or deletes records.

Watch out for: It helps write code. It does not operate a live store by itself.

Frequently asked questions

+Is Shopify Dev MCP the same as Shopify Storefront MCP?

No. Dev MCP helps developers write code using Shopify's documentation and schemas. Storefront MCP is a per-store endpoint that lets shopping assistants search a catalog and work with a cart. They solve different problems.

+Do I need a Shopify store to use it?

You do not need a store to look up documentation. You will need a development store or a real store when you actually build and test something.

+Can it edit my theme?

Not by itself. It helps an assistant write correct theme code. Applying the code to a theme is a separate step you perform and review.
