Link your WhatsApp

One QR code, about a minute. Your account becomes reachable from any MCP client — and stays yours: unlink it from your phone whenever you want.
Most clients can send you here themselves: add https://wacli.me/mcp as a server and let it ask for authorization — then there is no token to copy at all.

Press start, then scan with WhatsApp.

Also allow sending messages. Leave this off to link read-only — you can ask for it later.

Open WhatsApp on your phone Settings → Linked devices → Link a device. On Android it sits behind the three-dot menu.
Scan the code on the left It is WhatsApp's own linking code, the same one WhatsApp Web shows. It expires after a minute; this page keeps replacing it, so there is no rush.
Copy your endpoint and token They appear here the moment WhatsApp confirms. The token is shown once — put it somewhere safe.
Paste both into your client Instructions for Claude, ChatGPT and everything else appear below once you are linked.

What this does on our side. Linking creates a device session and a private store for your account, and syncs your history into it so search works. Nobody else's token can reach that store. Ask us to delete it and it is gone — see Privacy and Security.

You're linked

Add these two values to your MCP client. The token is a password for your message history — treat it like one.

  --header "Authorization: Bearer <token>"

Then ask it something: “What did I miss in the family group since Friday?”

History takes a moment. Your messages sync in the background after linking. Chats appear within seconds; older history keeps filling for a few minutes. history_coverage tells you how far back it reaches.
