Connect your Melba account to ChatGPT via Apps to drive your recipes, stocks, production and invoices in natural language. The connection relies on the MCP protocol (Model Context Protocol): no API key to copy-paste, and you keep full control over the scopes granted. It takes about two minutes.

Step 1 — Open the Apps catalog

In ChatGPT, open Apps & connectors from the settings menu, or visit chat.openai.com/apps.

Step 2 — Find Melba

Search for Melba in the gallery. If the app isn't listed yet, use Add custom app and paste https://mcp.melba.io.

Step 3 — Start the connection

Click Connect or Install. ChatGPT opens an OAuth window that redirects you to Melba.

Step 4 — Approve the scopes

Sign into Melba if needed, then approve the requested scopes. You can untick any scope you'd rather not grant, and revoke access at any time from your Melba account.

Step 5 — First prompt

Back in ChatGPT, try: "List my last 5 recipes" or "Parse my last Metro invoice". ChatGPT calls Melba and answers.
