Show HN: Give your AI agents access to WhatsApp

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

it looks like a dangerous. i can't trust the LLM

monononon34•about 2 hours ago

does it have any security system?

kreidema•about 2 hours ago

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?

asteroidburger•about 2 hours ago

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.

fabian_shipamax•about 2 hours ago

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

fabian_shipamax•about 2 hours ago

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.

blueplanet200•about 2 hours ago

Exactly. OP meant that it has permission to do anything, hence "admin".

lordgrenville•about 2 hours ago

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

gcgbarbosa•about 2 hours ago

This is ToS violation for sure. OP will soon receive a letter from Zuck's lawyers

fabian_shipamax•about 2 hours ago

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.

dpoloncsak•about 2 hours ago

...with the risk of getting banned, you can't reasonably use this for anything 'important'.

In order to make my life easier, it probably needs to be doing important stuff.

You can't hide behind 'other apps are doing it too', if my 'important business account' or whatever gets banned from using your tool, I'd be upset at you.

How do you guarantee your uptime SLA if my account may get banned any second?

LawrenceKerr•about 2 hours ago

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?

fabian_shipamax•about 2 hours ago

No it doesn’t.

fabian_shipamax•about 2 hours ago

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.

thomasjeff1•about 2 hours ago

That is normal when you lose your contacts and do an external backup. WhatsApp thinks I am texting large number of strangers whereas I already know those contacts. Happened to me. Lost access to WhatsApp.

Breaks ToS

Will be used to spam

liotier•about 2 hours ago

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

TZubiri•11 minutes ago

might be orthogonal to whether it's proprietary or Free Software in theory (although correlated in practice), couldn't a communication software be Open Source and free licensed BUT ask that users only use the software in a manual fashion and never automated?

A harder version of the clause, that only a specific interface be used, might be contrary to Free Software howeer, as it would infringe in the right to modify (the interface), but not the right to study the software.

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

robertclaus•about 2 hours ago

I'm much more concerned about the odds that this tool is vibe coded and will leak the conversations everywhere other than the LLM agent I've already vetted.

dpoloncsak•about 2 hours ago

This can be used locally, no?

testycool•about 2 hours ago

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

lbrito•about 2 hours ago

Most of the use cases in the page are personal, like Family Group, Sports Group and so on.

"Pick members and send them a personal direct message".

fabian_shipamax•about 2 hours ago

It’s a cloud product

dpoloncsak•about 2 hours ago

Sorry, I may has misphrased what I meant. Can I use this with a local model? Or is it locked to Claude

addag•about 2 hours ago

Oh gosh, if only it was just the whatsapp chats...
