Developers can now order food through ChatGPT using Zomato's MCP server, bypassing OAuth whitelist issues that plague other clients. The key is using ChatGPT Developer Mode, which is already whitelisted by Zomato's OAuth system. This unlocks features like restaurant discovery, menu browsing, and order placement directly within the chat interface.

The process involves enabling Developer Mode in ChatGPT settings, creating an app with the Zomato MCP server URL, and authenticating via phone number and OTP. While alternatives like Claude Desktop and VSCode fail with connection errors, ChatGPT's redirect URI is pre-approved, eliminating the common Node.js module and npm installation problems developers face elsewhere.

This workaround highlights a growing trend of platforms selectively whitelisting specific AI clients for API integrations. For developers, it offers a practical shortcut to building food ordering workflows without debugging OAuth errors. If Zomato expands its whitelist, the provided config for Claude Desktop could become universally useful.
