You want an AI agent — Claude, ChatGPT, Grok, Cursor or your own — to work with WhatsApp. The first decision isn't which model to use. It's **which kind of WhatsApp number** the agent should drive: an ordinary number linked the way WhatsApp Web is, or an official number on Meta's **WhatsApp Business API** (the Cloud API).

They behave very differently. One gives an agent everything you can do on your phone — groups, contacts, calls, reactions — but sits outside WhatsApp's terms of service. The other is the officially supported route for businesses, with a verified name and message templates, but it plays by Meta's rules and Meta's per-message pricing.

WhatsMCP supports both from one workspace and one MCP endpoint, so you don't have to commit to a single answer. This guide compares them side by side, walks through the trade-offs that matter for AI agents, and ends with a simple way to choose.

## The short answer

- **Choose a Personal number** if the agent works for *you*: your own chats, your groups, your contacts, your calls. Assistants, personal automation, small-team coordination, prototypes.
- **Choose a Business API number** if the agent talks to *customers*: support, bookings, order updates, notifications — anything at volume, or anything where a verified business name and compliance matter.
- **Use both** if you need both. In WhatsMCP each number has its own plan, and one workspace can mix Personal and Business numbers.

## How each one connects

### Personal number: a linked device

A Personal number joins WhatsMCP as a **linked device**, exactly like WhatsApp Web or Desktop. You scan a QR code from **WhatsApp → Settings → Linked devices** on your phone, and your phone stays the primary device. Your recent chats, groups and contacts come with it.

Because WhatsMCP connects to WhatsApp the way a WhatsApp client does, a new Personal number reaches WhatsApp through WhatsMCP's **Default Random VPN** (or through your own WireGuard tunnel or SOCKS5 proxy, if you prefer — see [egress options](/blog/whatsapp-egress-socks5-wireguard)).

### Business number: Meta's Cloud API

A Business number is registered on the **WhatsApp Business Platform**. In WhatsMCP you press **Connect with Facebook**, pick or create your WhatsApp Business Account in Meta's dialog, and WhatsMCP registers the number on the Cloud API. No phone has to stay online and no tunnel is involved: Meta's own infrastructure sends and receives.

## What the agent can do

| | Personal number | Business API number |
|---|---|---|
| Send and read messages | ✓ | ✓ |
| Images, documents, audio | ✓ | ✓ |
| Start a conversation | ✓ any time | Only with an approved **template** |
| Reply freely | ✓ | Within **24 hours** of the customer's last message |
| Message templates | — | ✓ create, list, delete, send |
| Groups and channels | ✓ create, join, admin | — |
| Contacts and profiles | ✓ | — |
| Reactions, edits, deletes | ✓ | — |
| Typing / presence | ✓ | — |
| Blocklist | ✓ | — |
| Call history and voice calls | ✓ on plans with voice | — |
| Webhooks for inbound messages | ✓ on paid plans | ✓ every plan |
| Verified business name | — | ✓ |
| Phone must stay linked | Phone stays the primary device | No phone needed |
| MCP tools available | up to 42 | 15 |

On a Business number, a tool that needs a Personal-only feature answers with a clear `backend_capability` refusal naming the feature, and `wa_list_accounts` lists each number's features up front — so an agent knows before it tries.

## Rules and risk

This is the part that should drive the decision for anything customer-facing.

**Personal numbers fall outside WhatsApp's terms of service.** WhatsMCP is an independent service, not affiliated with Meta, and connecting a number as a linked device for automation isn't something WhatsApp endorses. WhatsApp may restrict a number it sees as misused. That's an acceptable trade-off for a personal assistant on a number you can spare — keep traffic personal, no bulk or unsolicited messages — and the wrong one for your company's main customer line.

**Business numbers are the supported route.** Meta built the Cloud API for exactly this: businesses automating conversations with customers. The price of that is Meta's rules:

- **Templates to start conversations.** Anything that opens a conversation — or re-opens one after 24 hours — must use a template Meta has approved. See [how to write templates Meta approves](/blog/whatsapp-message-templates-meta-approves).
- **The 24-hour window.** Free-form replies are allowed for 24 hours after the customer's last message.
- **Opt-in.** Meta expects customers to have agreed to hear from you.

WhatsMCP checks the template and window rules before anything is sent, so an agent gets a refusal it can act on instead of a silent failure.

## What it costs

Both kinds of number are billed per number in WhatsMCP, on separate plan ladders — see [Plans](/plans) for current prices and limits.

- **Personal numbers** start free: your workspace's first Personal number takes the **free line** automatically, with a small daily message allowance, a few days of history and the core tools. Paid Personal plans add webhooks, groups and channels, longer history and voice calls.
- **Business numbers** have their own ladder — Business Starter, Growth and Scale — with higher limits and longer history. Your workspace's first Business plan starts with a **7-day free trial**.
- **Meta's fees are separate.** For a Business number, Meta charges per message under its own pricing and bills your WhatsApp Business Account directly; since 1 October 2026 that includes replies inside the 24-hour window. WhatsMCP adds no markup. Personal numbers have no Meta fees.

## Setup, side by side

| Step | Personal | Business |
|---|---|---|
| 1 | Create a workspace | Create a workspace |
| 2 | **Add a number → Personal WhatsApp → Link a device via QR** | **Add a number → WhatsApp Business → Connect with Facebook** |
| 3 | Scan from your phone's Linked devices | Pick your WhatsApp Business Account and number in Meta's dialog |
| 4 | First number takes the free line; others need a plan | Choose a Business plan (first one starts with a 7-day trial) |
| 5 | Egress: Default Random VPN, or your own tunnel | No egress step |
| 6 | Connect your AI client to `https://api.whatsmcp.com/mcp` | Same endpoint, same client |

The guides for each client cover both paths: [Claude](/blog/connect-whatsmcp-to-claude), [Claude + Business API](/blog/connect-whatsapp-business-api-to-claude), [ChatGPT](/blog/connect-whatsmcp-to-chatgpt), [ChatGPT + Business API](/blog/connect-whatsapp-business-api-to-chatgpt), [Grok](/blog/connect-whatsmcp-to-grok), [Cursor](/blog/connect-whatsmcp-to-cursor) and [Codex](/blog/connect-whatsmcp-to-codex).

## Which one for your use case

| Use case | Best fit | Why |
|---|---|---|
| Personal assistant: triage, replies, reminders | Personal | Needs your real chats, contacts and groups |
| Family or team group coordination | Personal | Groups are Personal-only |
| Prototyping an agent | Personal | Free to start, every tool available on higher plans |
| Customer support inbox | Business | Supported route, verified name, scales |
| Order, delivery and appointment updates | Business | Utility templates are made for this |
| Marketing messages | Business | Requires opted-in recipients and marketing templates |
| Call-centre or PBX bridging | Personal | Calls are Personal-only today |
| Both a personal assistant and a support line | Both | One workspace, two numbers, two plans |

## Can I use both?

Yes. Plans are per number, so a workspace can hold a Personal number for your own assistant and a Business number for customers. Your AI client connects once, to the same endpoint, and `wa_list_accounts` shows every number with its `backend` and `features`, so the agent picks the right one for each task.

## FAQ

### Is the WhatsApp Business app the same as the WhatsApp Business API?

No. The WhatsApp Business *app* is a phone app for small businesses; to WhatsMCP a number on it is linked like any Personal number. The WhatsApp Business *API* (Cloud API) is Meta's platform for programmatic messaging — that's what WhatsMCP's Business numbers use.

### Can an AI agent message customers who never wrote to us?

On a Business number, only with an approved template, and only to people who agreed to hear from you. On a Personal number, technically yes — but unsolicited messages are exactly what gets numbers restricted.

### Which is cheaper?

A Personal number can be free on the free line and never pays Meta. A Business number has a WhatsMCP plan plus Meta's per-message charges. For customer messaging, the Business API is still the right choice: it's the supported, scalable route.

### Do I need a different AI client for each?

No. Claude, ChatGPT, Grok, Cursor and Codex all connect to the same endpoint, and the same connection works for both kinds of number.
