Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Check a product CSV, handles, variant matrices and metafield keys. 4 of 6 free.

product_csv_check | Check a product CSV's header row against Shopify's current columns. FREE. Catches the failure that wastes the most time: a template copied from an out-of-date guide, using column names Shopify renamed. Typical input {"header_row": ["Handle" Inputs: header_row, mode |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.moltlinestudio.com/shopify. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
