Could you build this?

Partial The MCP wrapper and Cloudflare Workers plumbing are easy to vibe-code, but reading a personal WhatsApp account's messages has no official API, so the core data access depends on unofficial protocol work.

What it would actually take: The stack would be a TypeScript MCP server on Cloudflare Workers with a message store such as D1 or R2 and full-text search. The hard part is ingesting messages: a personal account needs an unofficial multi-device client (for example, a Baileys-style WhatsApp Web protocol implementation) running on a persistent host, because Workers cannot hold a long-lived WebSocket session. That requires reverse-engineering experience, handling of protocol changes and bans, and careful key and encryption handling.
