Connect Claude, ChatGPT, Codex, or Cursor to create and manage QR codes in your account.
Connect with a key for this Shopify store
Open QR Code Hub in your Shopify admin.
Open Settings → API, click Create New Secret Key, and copy the key when it appears. Then choose your assistant below. Replace YOUR_SECRET_KEY in its setup with your key.
Use the key from QR Code Hub, not your Shopify password or a Shopify Admin API token. Browser sign-in to QR Codes Unlimited connects standalone accounts, not your Shopify store.

Bearer YOUR_SECRET_KEY
Request headers are in limited beta. If you do not see that option, use Claude Code, Codex CLI, or Cursor below. Selecting No sign-in alone will not connect your store.
On a team account, your workspace owner may need to add the connector first.
Claude’s connection guideClaude CodeConnect from your terminal
With Claude Code installed, run this command in your terminal, after replacing YOUR_SECRET_KEY with the key you copied:
claude mcp add --scope user --transport http qrcodes https://staging.qrcodesunlimited.com/mcp --header "Authorization: Bearer YOUR_SECRET_KEY"
Open Claude Code and run /mcp to check that qrcodes is connected. You can now ask it to work with this store’s QR codes.
Codex CLIConnect with your store’s API key
With Codex CLI installed, run these commands in your terminal, replacing YOUR_SECRET_KEY with the key you copied:
export QRCODES_API_KEY='YOUR_SECRET_KEY' codex mcp add qrcodes --url https://staging.qrcodesunlimited.com/mcp --bearer-token-env-var QRCODES_API_KEY codex
Start Codex from that same terminal so it can read your key. Set QRCODES_API_KEY again when you open a new terminal.
CursorConnect from your editor
Add this entry to ~/.cursor/mcp.json. If the file already contains servers, add qrcodes inside its existing mcpServers object.
Replace YOUR_SECRET_KEY with the key you copied from this store.
{
"mcpServers": {
"qrcodes": {
"url": "https://staging.qrcodesunlimited.com/mcp",
"headers": {
"Authorization": "Bearer YOUR_SECRET_KEY"
}
}
}
}
Open Cursor’s Customize page and find qrcodes under MCP servers. Make sure the server is enabled. Start a new agent chat to use it.

Look for an option to add a remote MCP server using Streamable HTTP. Use the server URL above and an Authorization header containing Bearer followed by your store’s API key.
