About whatsapp-mcp

Let your AI agent read your WhatsApp messages.

This is a small server that runs in your own Cloudflare account. You link your phone to it once, the way you'd link WhatsApp Web, and from then on any MCP client (Claude Code, Claude Desktop, anything that speaks MCP) can search and read your chats. It can read and search your messages, and remember names you give it for phone numbers. It can't send anything.

- "What did Dana say about the flights?" - "Find every message where someone mentioned the lease, across all my chats." - "Summarize what I missed in the family group this week."

Your phone stays the source of truth. The server is a linked device that your agent talks to.

It doesn't stay connected to WhatsApp. When your agent asks for something, and once a day, it connects, collects whatever WhatsApp queued for it since last time, writes that to its own database, and hangs up. Your phone keeps working normally and keeps getting notifications.

Your messages live in a SQLite database inside a Durable Object in your Cloudflare account. Nothing goes anywhere else.

You need a Cloudflare account on the Workers Paid plan (see the note below), Node 20 or later, and your phone.

Wrangler prints your URL, something like https://whatsapp-mcp.your-name.workers.dev. Open it. The front page has the two remaining steps:

1. Link WhatsApp. Scan the QR code with WhatsApp (Settings, Linked Devices, Link a Device). If you're on the phone itself and can't scan a screen, use the phone number option instead. The first link imports your history. The page shows progress, and you can close i
