Add the connector
In Claude, open settings, go to connectors and add a custom connector with the URL https://nilyo.com/mcp, choosing OAuth. Claude registers itself and opens a browser once so you sign in and authorize the accounts it may reach. The same connected account is then available on claude.ai, in the desktop app and in Claude Code.
Pair the number by QR code
WhatsApp itself is connected in Nilyo by scanning a QR code from your phone, the same pairing the desktop app uses. The code refreshes every forty seconds or so, and your phone can go offline afterwards. No Business account, no templates, no brand number.
Long threads are the use case
Ask what was agreed rather than what was said last. Claude reads the exchange in order, distinguishes the decision from the small talk around it, and tells you what is still open — which is work nobody does by scrolling back through six weeks of messages.
“Read my conversation with the supplier and tell me what we agreed on delivery.”
“Which WhatsApp conversations are waiting for an answer from me?”
Reading sends nothing
Listing and reading are read-only: nothing is marked read for your correspondent and no receipt is sent. Replying is a separate action you request, and when several contacts match a name nothing is sent and Claude asks which one.
Twenty new conversations a day
Brand new chats are capped at twenty per day per account and spaced fifteen seconds apart; replies inside existing conversations are unrestricted. Put the rule you want in a Project instruction — never contact someone who has not written first, for instance — and every conversation in that project inherits it.
Next to your other accounts
The question people actually ask is rarely per-channel. With LinkedIn and a mailbox connected too, did anyone ask about the September order, anywhere is one answer instead of three searches, and WhatsApp stops being the channel nobody checks.
Common questions
Can Claude read my WhatsApp?
Yes, once the number is paired by QR code. It lists conversations, reads threads and replies when you ask; reading never sends anything.
Do I need WhatsApp Business?
No. A personal or business account pairs the same way. The Business Cloud API and its templates belong to the brand-number route.
Does my phone need to stay on?
No, the session is independent once paired, like any linked device.
Can it answer automatically?
Only if you ask for that explicitly, and the sane version is one reply per person rather than a loop. Reading never sends by itself.
How WhatsApp works with Nilyo
Connection. Scan a QR code shown in the conversation (WhatsApp › Linked devices), or type a pairing code on your phone. The line stays linked like any other device.
What your agent can do. Contacts and chats, message history, text, media and native voice notes, reactions, groups, checking whether a number is on WhatsApp.
Pacing and safety. 20 new conversations per day with 15 seconds between them; existing chats are not limited beyond serialization.
- “Send a WhatsApp to Julien” resolves the person among your recent chats and contacts; two matches mean the agent asks.
- Disconnecting from the phone marks the account for reconnection; the same account is re-linked with a new QR, never duplicated.
