Show HN: WhatsApp MCP – An MCP server for interacting with WhatsApp (github.com)

A new open-source project named WhatsApp MCP (Model Context Protocol) allows AI agents to interact seamlessly with individual WhatsApp accounts while prioritizing user privacy. By linking a server to a WhatsApp account via a QR code, users can enable their AI agents—such as Claude Code and Cursor—to read chats, send and receive messages, and handle media without revealing their phone numbers. All data, including messages and contacts, is AES-256-GCM encrypted and stored on the server, ensuring that personal information remains protected even as agents access and process it. The significance of WhatsApp MCP for the AI/ML community lies in its potential to bridge the gap between artificial intelligence and popular communication platforms. With real-time message handling, customizable toolsets, and protections against unwanted bans, this solution empowers developers to create more sophisticated AI-driven applications for messaging. However, users must be cautious, as the software operates through an unofficial client, which may violate WhatsApp's terms of service. Thus, while it holds promise for enhanced interaction capabilities, adherence to legal and compliance requirements is crucial for users employing this tool.
