How do I connect Claude, ChatGPT or Cursor to QRCodeStack?

Claude

1. Open Customize → Connectors in Claude.
2. Add a custom connector and paste https://qrcodestack.com/mcp.
3. Claude opens our authorize page. Sign in and click Authorize.
4. In a new chat, try: Create a trackable QR code for https://example.com/summer named "Summer flyer".

If QRCodeStack already appears in Claude's connector directory, add it from there instead of pasting the URL.

ChatGPT

1. Open Settings → Apps / Connectors. Turn on developer mode if the public listing is not available to you yet.
2. Add the same URL: https://qrcodestack.com/mcp.
3. Sign in on the authorize page and approve the access.

Cursor

Go to Settings → MCP → Add new MCP server and choose HTTP (Streamable HTTP):

{
  "mcpServers": {
    "qrcodestack": {
      "url": "https://qrcodestack.com/mcp"
    }
  }
}

If Cursor asks you to sign in, that is the same authorize page Claude uses. The full public setup notes live on the connector page.

What the assistant can and cannot do

The server offers 19 tools, in four groups:

• Account — check which account is connected and how close it is to its quota.
• QR codes — create a dynamic code, list and search codes, fetch one, repoint or rename it, and read its scan analytics.
• Short links — list, fetch, create, update and delete short links.
• Domains — list, add, verify and remove a branded short-link domain, and the same four for a white-label QR scan domain.

Reads run without interrupting you. Anything that creates, changes or deletes asks you to confirm in the assistant first.

Permissions and revoking access

The consent screen lists exactly what you are granting. Most clients ask for two permissions: view your QR codes, and create and update them. A client that also wants short links asks for two more — view your short links and their click analytics, and create and update them.

We do not push your data to Claude, ChatGPT or Cursor; their client calls us with a token you issued, and that token expires. To revoke a connection, remove the connector in the assistant and email support@qrcodestack.com from the address on the account.

Common problems

Authorizing works but every tool call fails

You are on the free trial. The consent screen is open to trials, tool calls are not — they unlock when the trial ends or you subscribe.

The assistant says it is missing a scope

The connection was approved without the permission that tool needs, most often the short-link permissions. Remove the connector, add it again, and approve everything the consent screen lists.

The assistant made up a QR code image instead of using the tool

Ask it directly to use QRCodeStack — for example use the QRCodeStack connector to create a trackable QR code for this link. A drawn image is not tracked and cannot be repointed.

Nothing connects from Cursor

Check the server type is HTTP / Streamable HTTP rather than a local command, and that the URL has no trailing path after /mcp.
