How to Connect Muse to WhatsApp (No Code, 2-Minute Setup)

If your customers, suppliers and team all write to you on WhatsApp, you probably spend a big part of your day scrolling through chats. Once you connect Muse to your WhatsApp, you can just ask:

  • "Who's waiting for a reply from me since yesterday?"
  • "What did the supplier group decide about Friday's delivery?"
  • "Tell Ana we have it in blue and I can deliver Thursday."

Muse reads your chats, finds what you need, and sends messages from your own number, but only when you ask it to.

This guide shows you how to set it up with WhatsApp MCP. There are no settings to dig through: you copy one prompt, paste it into a Muse chat, and Muse does the rest. You don't need to install anything, write code or get a new number, and it takes about two minutes.

What you need

  • WhatsApp on your phone. Regular WhatsApp or WhatsApp Business, with the number you already use.
  • Muse by Meta. The Muse app on your phone (iPhone or Android) or on your computer. Any Muse plan works, including the free one. You set it up once and it works in all of them.
  • Two minutes, with your phone nearby.

You don't need a new phone number, Meta's WhatsApp Business API, a developer, or a server.

Step 1: Get your setup prompt

  1. Go to wa-mcp.com.
  2. Under Which AI do you use?, choose Muse.
  3. Click Generate my Muse link.
  4. You'll see a prompt with your personal WhatsApp link already in it. Click the copy button to copy the whole prompt.

Save your link somewhere safe, like a password manager or a private note. It's shown only once, and it works like a password: anyone who has it can use your WhatsApp. For the same reason, don't share the prompt or a screenshot of it. If you ever lose the link, generate a new one and link the same phone. Your account and subscription carry over.

Step 2: Paste the prompt into Muse

  1. Open Muse and start a new chat.
  2. Paste the prompt and send it.

Muse saves WhatsApp MCP as a custom connector, stores your link securely, and checks that the connection works before it tells you it's done. If Muse asks you to allow the connector or one of its actions, choose Allow.

That's it for Muse. The connector is saved to your Muse account, so later chats can use WhatsApp without pasting anything again, on your phone and on your computer. You can find it under Settings → Connectors.

Step 3: Link your WhatsApp

Right after the setup, Muse asks how you want to link your WhatsApp. There are two ways:

With a QR code (best if Muse is open on your computer)

  1. Muse shows you a QR code.
  2. On your phone, open WhatsApp → Settings (iPhone) or the ⋮ menu (Android) → Linked devices → Link device.
  3. Scan the QR code.

With a pairing code (best if you're using Muse on the same phone)

  1. Choose the pairing code and give Muse your phone number with country code.
  2. Muse gives you an 8-character code.
  3. In WhatsApp, go to Linked devices → Link device → Link with phone number instead, and type the code.

This is the same way WhatsApp Web links to your account. WhatsApp MCP shows up as a linked device, and you can remove it from that screen at any time.

Step 4: Try it

Start with a few questions to see how it works:

  • "Who's waiting for a reply from me in the last 24 hours?"
  • "Summarize my chat with Carlos from this week."
  • "Find the address Laura sent me."
  • "Tell Ana I'll be there at 7."

Before sending anything, Muse should confirm the recipient and the message with you. Nothing goes out unless you ask for it.

What Muse can see after you link

When you link a new device, WhatsApp shares some of your recent messages with it, the same as when you open WhatsApp Web for the first time. From then on, every new message is available.

  • Muse can read the recent messages in a chat, including what WhatsApp shared when you linked.
  • Search covers messages that arrived after you linked, up to the last 90 days.

So if you link today, "What did we quote John last week?" may find nothing yet. A week from now it will.

How much it costs

  • Free trial: 1 hour of every feature, no credit card.
  • After that, free: Muse can still read, summarize and search your chats and send text messages to people who've written to you in the last 90 days. Messages it sends end with "Sent via wa-mcp.com".
  • Pro: removes that line and adds sending files, scheduling, and editing, reacting to and deleting messages. US$9/month, US$7/month billed quarterly, or US$4/month billed annually. Every plan has unlimited use.

To subscribe, just ask Muse: "Subscribe me to WhatsApp MCP." It gives you a secure Stripe checkout link.

If something doesn't work

  • The QR code expired. Ask Muse for a new one.
  • Muse doesn't seem to know about WhatsApp. Start a new chat and ask "Is my WhatsApp connected?". If that doesn't help, check that the WhatsApp connector is still under Settings → Connectors.
  • The setup failed or Muse says the link is wrong. Remove any WhatsApp connector under Settings → Connectors, start a new chat and paste the prompt again. Don't paste it into the same chat twice, or you may end up with two connectors.
  • You lost your link. Generate a new one at wa-mcp.com, remove the old connector under Settings → Connectors, paste the new prompt into a new chat, and link the same phone. Your account and subscription carry over.

Frequently asked questions

Does it work with WhatsApp Business? Yes. It connects to the number you already use, on regular WhatsApp or WhatsApp Business. There's no new number and nothing to migrate.

Will my customers know Muse sent the message? No. Messages go out from your own number, exactly as if you had typed them.

Can this get my number banned? To WhatsApp, it's a normal linked device, like WhatsApp Web. Most bans come from sending too much, too fast, especially to people who never wrote to you, so WhatsApp MCP has guardrails built in: “typing…” before every message, no bulk sending, and new conversations spaced out (at most 1 a minute and 10 every 12 hours). Chats with people who've written to you aren't limited. Other WhatsApp tools send whatever the AI asks. No tool can fully remove the risk on an unofficial connection, but this keeps your usage looking like a person, not a bot.

Does my phone need to stay on? No. Linked devices work on their own, so your phone can be off or offline.

Can I keep using WhatsApp on my phone as usual? Yes. Nothing changes on your phone.

Is my data private? WhatsApp MCP stores your messages only so Muse can search them, and deletes them automatically after 90 days. Your data is never sold or used to train AI models. The messages Muse reads are also processed by Meta under its own privacy policy, as with anything else you share with Muse.

Muse and WhatsApp are both Meta. Is this an official Meta product? No. WhatsApp MCP is an independent product. It isn't made, endorsed or sponsored by WhatsApp or Meta. It connects to your WhatsApp as a linked device, and to Muse as a custom connector.

Can I connect two numbers, like personal and work? Yes. Generate one link per number and paste each prompt into its own new chat, so you get two connectors, for example "WhatsApp Personal" and "WhatsApp Work". Each number needs its own subscription.

How do I disconnect or delete everything? Ask Muse to "unlink my WhatsApp", or remove the device under Linked devices in WhatsApp. To remove WhatsApp from Muse, disconnect it under Settings → Connectors. To delete your account and data, ask Muse to "delete my WhatsApp MCP account". That also cancels your subscription. Your WhatsApp account and chats on your phone aren't affected.
