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…

Hey Hacker News, I’m excited to share a tiny service that’s very close to my heart - Today Has Been. Here’s how it works: We have a phone number that has WhatsApp Business API enabled. Your messages sent to this number (after you activate your free trial) are added to your journal. It’s a super light weight journaling service - no app download or registration is required. We also send you a daily nudge asking “How did your day go?” and after you have a few posts we send you a random blast from the past. Why I built it: I was an active user and fan of Ohlife - only journalling app that could…

Hey HN, I'm Andres. I've been building Kapso as a solo founder, and just crossed 4,000 developers, all organic. WhatsApp has 3B+ users and 98% open rates. You'd expect developers to be building tons of stuff on it, especially when the US is the fastest-growing market in WhatsApp usage. But it’s not happening… And I'd bet it's because the DX is painful. Every team needs to build the same features again and again. Meta fires webhooks for everything. There's valuable data in there for debugging, but no way to make sense of it without building your own tooling. That’s why I built Kapso. What you…

Hey HN, I'm Pau. We've been building Zernio for the past 9 months and we just crossed $1M in ARR (bootstrapped). Zernio is a unified API for social platforms. One API for Instagram, TikTok, YouTube, LinkedIn, X, and 9 others. Today we're adding WhatsApp. We've spent 3 weeks just getting a test message to send. Meta requires a developer app, a WhatsApp Business Account inside Business Manager, business verification (2-14 days), phone number OTP, webhook configuration with a two-step subscription, and token management for tokens that die every 60 days. Miss one step and messages vanish with no…
