# Third-party AI agents  
_inside WhatsApp_

A new WhatsApp setting lets you add your own AI agent as a chat. Here is how it connects, what it can and cannot see, and when you need a connector that works on your whole account instead.

What is new

## What are WhatsApp third-party agents?

WhatsApp third-party agents are AI agents or bots, hosted by another service, that you add as a chat inside WhatsApp. [WABetaInfo reported the feature](https://wabetainfo.com/whatsapp-is-rolling-out-chats-with-third-party-agents/) on September 4, 2026 in WhatsApp beta for Android 2.26.35.3, rolling out gradually to more accounts.

You create an agent from the app settings: a name, an optional photo, and WhatsApp generates an API key. You paste that key into the service that runs the agent, which can be built on the agent platforms of companies like OpenAI, Google or Anthropic. From then on the agent answers you in its own chat.

The limits are clear. Up to five agents per account. Agents work in individual chats only, not in groups or communities. An agent sees what you share in its chat, not your other conversations, contacts or media. And those chats are not end-to-end encrypted: the agent's developer can access the messages, while your personal chats stay encrypted.

So a WhatsApp agent is someone you talk to, not something that acts on your account. If you want an assistant to read a thread with a client, draft the reply and send it from your number, or to send the same message by email, you need a different tool: an MCP connector on your linked account.

Definition
Third-party agent (WhatsApp)

An AI agent or bot run by an outside service and added as a chat in WhatsApp through an API key that WhatsApp generates. It only sees the messages exchanged in that chat.

Shown in the WhatsApp settings as Agents.

How it connects

## Adding a third-party agent, step by step

1. 01  
### Open the Agents setting  
On an account that has the feature, create a new agent from the app settings.
2. 02  
### Name it  
Give it a name and, if you like, a profile photo. That is how it appears in your chat list.
3. 03  
### Copy the API key  
WhatsApp generates an API key for this agent.
4. 04  
### Paste it where the agent runs  
Enter the key in the service hosting your agent. It can then receive and answer the messages you send in its chat.

Two different jobs

## WhatsApp agent chat or an MCP connector on your account

One is a chat with a bot. The other gives the assistant you already use tools to work on your WhatsApp and email.

Setup

## Give your assistant your WhatsApp instead

1. 01  
### Create a free account  
Sign up at app.unlimitedmessaging.app, without a credit card, and link your WhatsApp number by QR code, like WhatsApp Web.
2. 02  
### Add the connector  
In Claude, ChatGPT, Claude Code or Cursor, add the MCP server https://mcp.unlimitedmessaging.app and approve the OAuth sign-in.
3. 03  
### Ask in plain language  
"Summarize what Paul sent me this week and draft a reply": the assistant reads the thread, shows the draft and sends it from your number when you confirm.

Good to know

### Privacy works differently in both cases

A WhatsApp agent chat is readable by the agent's developer. A connector also passes messages through the service and your AI provider. Share only what you would share with that provider, and keep a human check before anything is sent. UnlimitedMessaging is not affiliated with Meta.

FAQ

Up to five per account, according to WABetaInfo's report on the beta for Android 2.26.35.3.

No. Chats with third-party agents are not end-to-end encrypted, and the agent's developer can access those messages. Your personal chats and calls stay end-to-end encrypted.

The feature is rolling out gradually, starting with some beta users on Android. WhatsApp has not announced when every account will get it.

A WhatsApp agent is a bot you chat with. An MCP connector gives an assistant like Claude or ChatGPT tools to read your chats and send messages from your number, and with UnlimitedMessaging, emails from your own mailbox too.
