Show HN: Give your AI agents access to WhatsApp

read original more articles
Why This Matters

This Show HN highlights a growing trend of developers building lightweight middleware to connect AI agents to consumer messaging platforms like WhatsApp, which lack official easy-to-use APIs for automation. Tools like Chat-Man could lower the barrier for businesses to integrate WhatsApp into CRM and automation workflows, but they also raise questions about compliance with WhatsApp's terms of service and data protection laws like GDPR.

Key Takeaways

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
