Show HN: WhatsApp MCP running free on Cloudflare(github.com)

I wanted my humble Claude on mobile to access my WhatsApp messages but the only options I could find either required WhatsApp Business or an actual server to run Baileys on.

I wanted to run it for free on ClaudeFlare and with my personal WhatsApp account, so I built this.

Important feature - it connects to your Google account as well as WhatsApp to grab the names of all your WhatsApp contacts, otherwise you get only phone numbers for many of them and search doesn't work properly.

This is a single user install because it's both gray area and very private - so point your agent at the repo and let it set things up.

I am not saying this proudly, but given how important is to stay in touch with others, I would never jeopardize my Gmail account and my Whatsapp account. Understand that using a bot to access your Whatsapp account is against TOS and your account could be suspended.

What bothers me about these projects is you are exposing the other side of your conversations to being uploaded to a 3rd party AI company who will ingest it in to their training data. You personally might not care about this privacy intrusion but the people you are messaging never consented to this.

I agree with you on principal but also think that from a practical point, that ship has long sailed.

It's always been a possibility that when you sent an email to someone their provider could be building an ad profile on you. Any third party tool someone else uses to manage their personal files and communications could always have some arbitrary privacy policy that let them do what they see fit.

For the most part, you never know what random SAAS someone on the other end of a relationship is really using.

Yes, and that's exactly why E2EE messaging became a thing. Signal put it on the map through the WhatsApp integration.

To me there is a difference if the server spies on me (that's without E2EE) or if the person I am writing to leaks everything on the Internet.

If the person you're writing to leaks everything on the Internet, you should consider you are talking to them in public. I'm sure you don't say all the same things when you are in the metro or when you are in private, or do you?

Yes but I'd say some people (me) like WhatsApp because of the privacy and end-to-end encryption. Email i assume is less private but still more private than a public post.

Imagine someone puts all the Signal messages someone else sent them through an AI. I dunno. I think problem is most AI doesn't work like Confer.to, also by Signal's founder.

This ship has sailed about two decades ago. At least let's get some cool products out of it.

This has been happening for years... I distinctly remember people giving access to contacts to Whatsapp and having the entire contacts slurped into their cloud.

There is a big difference between leaking the contacts (that is, metadata) and the conversations themselves.

Not like Meta is a saint...since they're competitors

True but WhatsApp is end-to-end encrypted so they shouldn't see any of your messages anyway.

They're using a Facebook product. The privacy damage already occurred.

WhatsApp is end-to-end encrypted, that's probably* better than using Telegram.

* Unless you want to go into a conspiracy theory that all the Meta employees can see the source code and nobody has ever felt like whistleblowing about the backdoor Meta put into WhatsApp, that is.

You never know what the people you're talking to are doing with your data. This isn't any different. The conversation involves 3 parties: Sender, WhatsApp & Recipient. If you want your conversation to be private, you must trust all 3.

I never know that the people preparing my food at the restaurant are doing with it either but if I see someone doing something wrong I'm going to call it out. We should all make an effort to maintain some level of ethics even if we don't have total control over the environment.

Feeding someone else's personal data in to an AI company is unethical even if there is no way as an individual to prevent someone doing that.

I don't get how of the personal assistant can be useful without having to see my conversational data so this is great.

Do you know if running Whatsapp in Cloud risks your account to be banned?

I'm working on a similar tool, connecting all that data to build your context graph that knows all the people and conversations and expose it via MCP. https://lobu.ai/for/personal/

My approach is requiring you to have a home device where you keep your accounts open in a browser and observing the data from there. The same applies to Linkedin, Instagram, X etc. even reading my timeline to summarize what I need to know without me doomscrolling.

AI built me an Android gateway that can send/read text messages along with connectivity to my local AI over wireguard.

If a bot needs to text me it sends an API request or it can read whatever I allow with full visibility as I have the logs and limit the access.

The amount of effort was minimal. About 4 prompts to get it all working and zero SaaS, 3rd party, or purchases after the software was built.

I've experimented with some of these whatsapp-web-esque hacks (whatsappweb.js, whatsmeow, ...) and every now and then I'll get banned. It's quite inconvenient if you live in a country where WA is the universal contact channel for pretty much everything.

I've been using Baileys - but it's not ideal. (Periodically you have to go manually log the bot back in.) Is there no platform that's friendly to personal bots? Or is that what Telegram is for? Discord I suppose...

While I see the security concerns I would like to point out that this project is interesting and a great stepping stone for easier to make whatsapp AI support chat bots.

Much safer to just use Meta Business Agent, avoids bans.

Interesting approach, we did kaptionai.com/mcp with a slightly different approach, the MCP runs on your own WhatsApp Web or in our own app, it can run locally or through our own bridge (which is open source as well).

The big difference is that we support attachments and transcribe the audios, we've been in business for over 4 years.

Cloudflare already sniffs most of the internet traffic, why not also let them see our private messages?!

What does cloudflare contribute? free hosting or

throwaway27448 3 hours ago | |

Like, is clouflare just a saas for hosting memcached or does it provide some distinct sense of value that the rest of us don't see?
