Connect ChatGPT and Cursor

Both ChatGPT and Cursor connect to Máximo’s server URL, https://app.getmaximo.ai/mcp, and sign you in through your browser with your email. There’s no token to copy. Cursor needs only the URL, while ChatGPT needs a setting turned on first.

Cursor

Section titled “Cursor”
  1. Open (or create) ~/.cursor/mcp.json for every project, or .cursor/mcp.json inside one project.
  2. Add a maximo entry:
{
  "mcpServers": {
    "maximo": {
      "url": "https://app.getmaximo.ai/mcp"
    }
  }
}
  1. Save the file. In Cursor’s MCP settings, Máximo shows that it needs you to sign in. Select it, and a Máximo sign-in page opens in your browser.
  2. Enter the email you use in your Shopify admin, then the 6-digit code Máximo emails you.
  3. Choose which stores Cursor may use (all of them by default), then select Allow access. You’re sent back to Cursor.
  4. In Cursor’s Agent mode, ask something about your catalog. Cursor should call a Máximo tool to answer.

ChatGPT

Section titled “ChatGPT”

ChatGPT connects to custom MCP servers through Developer Mode, which is off by default and only available on a plan that supports it.

  1. In ChatGPT, open Settings, then find Developer Mode (it lives under Connectors → Advanced, or under Security and login depending on your account) and turn it on.
  2. Open Settings → Connectors, and add a custom connector.
  3. Enter a name (for example, “Máximo”), and set the Connector URL to https://app.getmaximo.ai/mcp.
  4. For authentication, choose OAuth.
  5. Save. A Máximo sign-in page opens: enter your email and the code Máximo sends you, choose your stores, and select Allow access. ChatGPT then connects and lists the available tools.
  6. In a new conversation, enable the Máximo connector from the composer’s connector picker, then ask your question.
