Show HN: WhatsApp MCP running free on Cloudflare (github.com)

A new project, named WhatsApp MCP, allows users to leverage AI agents to read their WhatsApp messages through a small server hosted on Cloudflare. By linking the server to their WhatsApp account (similar to WhatsApp Web), users can utilize any MCP-compatible AI client, like Claude, for read-only access to their chat history. This means users can ask questions such as "What did Dana say about the flights?" or "Summarize my family group messages this week." The server connects once daily to sync messages, ensuring the user's phone retains its functionality while data remains private within a SQLite database on the Cloudflare platform. This development is significant for the AI/ML community as it showcases the integration of AI agents with popular messaging platforms, enabling enhanced search and summarization capabilities using AI. Although leveraging WhatsApp's protocol in this way raises legal concerns since it violates WhatsApp's terms of service, the project's technical implementation—using Cloudflare Workers and Durable Objects—offers a practical approach to accessing personal messaging data without sending it to external servers. It highlights the potential for personalized AI tools to improve our interaction with existing communication technologies.
