Show HN: Free WhatsApp MCP (+UI) – Give Your AI Agents Access to WhatsApp

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.
