Show HN: WhatsApp MCP Server

Hi HN – I built an open-source, self-hosted Model Context Protocol (MCP) server for WhatsApp: https://github.com/lharries/whatsapp-mcp

It connects to your personal WhatsApp account via the WhatsApp Web multi-device API (using whatsmeow from the Beeper team), and doesn't rely on third-party APIs. All messages are stored locally in SQLite. Nothing is sent to the cloud unless you explicitly allow your LLM to access the data via tools – so you maintain full control and privacy.

The MCP server can:

- Search your messages, contacts, and groups

- Send WhatsApp messages to individuals or groups

Why build this?

99% of your life is stored in WhatsApp, by connecting an LLM to WhatsApp you get all this context. And your AI agent can execute tasks on your behalf by sending messages.

This is incredibly cool, thank you

The why is because we can, but damn am I finding the tools being built with, or having tacked on, AI depressing. Is this a small glimpse of the future we're building for ourselves? Communication is valuable because thought and effort went into it, lowering the bar on producing content doesn't mean more choice, it means lower quality. Already I see a reaction against this amongst some peers when they find out something they were asked to review was AI generated, why should they put effort in if the other person didn't.

I think this is like the 7th or 8th WhatsApp MCP implementation.

I really have zero understanding why people think this is something crazy. It’s not. It’s importing the official MCP packages and wrapping basic API methods with an MCP tool decorator.

You can even ask Claude or ChatGPT to make your MCP tools for you and they will write this same code in 1 minute.

I can’t wait until the community realizes that MCP servers are literally just regular methods with a one line decorator and these posts just get downvoted for being incredibly low effort.

It’s basically the same as upvoting someone saying “hey guys, I wrote a method which connects to the WhatsApp API”, that’s it, really.

The way to absolute dominance of WhatsApp with the Normies has't been sufficiently analyzed, I reckon. Somehow, WhatsApp managed to become extremely popular and heavily used by people who have trouble switching on a desktop pc. Even senior citizens have no trouble using it.

Is it because they have a high motivation to use it? The UI / UX of WhatsApp surely isn't great, I'd even say it's quite bad. Where am I wrong? What am I not seeing?
