Show HN: Free WhatsApp MCP (+UI) – Give Your AI Agents Access to WhatsApp

11 pointsby 45m ago

Hi,

I built Chat-Man because I wanted a cheap way to give my agents access to WhatsApp without integrating a WhatsApp library separately in every project.

You get WhatsApp MCP server, so you can connect WhatsApp to an agent and programmatically read, search, extract and send messages - but also have a web UI for non-techies.

You can also receive webhooks for incoming messages for starred conversations.

What you can do with the MCP? -Read WhatsApp messages and turn them into CRM records -Summarise conversations or groups -Extract structured information from messages -Find messages, participants or other WhatsApp data -Send messages -Manage group memberships

Of course.. you always need to follow data protection regulation.

The web UI: -Edit group details -See who joined or left -See who is most active -Export group members -Match members against a CSV (e.g. from a CRM) -Bulk message members -Bulk kick members -Create invite links For individual contacts, you can send messages directly from the UI.

Why I built it for myself? I needed WhatsApp access for several projects (hermo.ai, florahaus.co.uk, …) and didn't want to pay for a WhatsApp integration for each project.

I’d love to get some feedback, especially from people building agents that need access to WhatsApp. Fabian

Do I understand correctly that your service works as a registered device into my whatsapp account with full "admin" like access? This seems a bit harsh for the sensitive data that peoples wahatsapp contain? Or am I missing a usecase here where that is unproblematic? Business accounts maybe?

24m agoHN ↗

Businesses should be using WhatsApp business accounts. They cost money per message sent and don’t support groups, but it’s the officially sanctioned way to do it.

22m agoHN ↗

Businesses can use the official API which is costly and takes time to set up. Correct.

22m agoHN ↗

Not quite sure what you mean with admin access. There no such concept. But you can basically do anything a user can do - but via MCP.

Does this require a Meta / WhatsApp business account?

If not, is this a solution using WhatsApp Web in the backend (like Baileys does)? If this is the case, how does your solution avoid getting blocked or banned? I used Baileys once in an MVP with only 7 users, and my agent got blocked really quickly after just a few days of using it. So I guess the official path is the only way to go?

23m agoHN ↗

If you use it for personal and not excessively you won’t get banned is my experience. You if you start messaging new contacts on a large scale you probably will.

22m agoHN ↗

Am I correct in guessing that this is a ToS violation and could lead to getting blocked?

18m agoHN ↗

You are right that this is a consideration and risk. But it can make your life much easier. The reality is that these tool are available now. This is in fact not the first one like this. It can make the work of small businesses or clubs more more efficient.

Any opening of proprietary chat to useful tools will be used for spam too. It is a curse.

Are people really this nonchalant about giving away their private whatsapp conversations to the likes of Anthropic and Openai?

And you typically use them for business, not on private accounts.
