[Create a free account](https://app.unlimitedmessaging.app)[See pricing](https://unlimitedmessaging.app/pricing) The concept ## How do you get ChatGPT to send and read WhatsApps? The Model Context Protocol (MCP) is an open standard that describes how an assistant like ChatGPT discovers and calls external tools; [the MCP protocol](https://modelcontextprotocol.io) has become the foundation of connectors on OpenAI's side. Concretely, you add UnlimitedMessaging's MCP server as a connector in ChatGPT. From there, you talk to ChatGPT as usual: "Tell Léa on WhatsApp that I'll be late", or "Summarize my latest WhatsApp messages". ChatGPT understands the intent, picks the right tool and runs it - no copy-paste, no macro to set up. The server relies on your normal WhatsApp account, already linked to UnlimitedMessaging. So messages go out from your usual number, seen by your contacts like any WhatsApp - with no Meta Business account, no template approval and no per-message billing. Access is protected by an OAuth flow: you authorize ChatGPT once, you stay in control, and you can revoke the connection at any time. It's the opposite of a Zapier script or a patched-together webhook that holds keys in plain text and breaks at the slightest change. ![Illustration: a laptop showing a chat conversation.](https://unlimitedmessaging.app/_next/image?url=%2Fassets%2Farticles%2Fcovers%2Fmcp-chatgpt-en.png&w=3840&q=75) Definition MCP connector for ChatGPT An MCP connector is a server that exposes tools (read messages, send a WhatsApp, list conversations) to an assistant like ChatGPT. Once added in ChatGPT, the model can call these tools on its own whenever your request calls for it. Also called: ChatGPT MCP server, ChatGPT connector, ChatGPT WhatsApp integration, ChatGPT WhatsApp agent.
