How it works

Claude talks to your inbox. In three steps.

Once you've added Wassenger as a custom MCP connector in Claude (a five-minute setup in Customize → Connectors), Claude can read your WhatsApp inbox, find contacts, draft and send replies, and trigger your automations — all from a normal conversation. No code. You stay in control: Claude asks before sending anything.

1

You connect Claude once

Open Claude Desktop → Customize → Connectors → Create custom MCP. Paste your Wassenger MCP URL and API key, then connect. Five minutes, one time. The same flow works with ChatGPT, Cursor and other AI assistants.

2

You ask Claude in plain English

“Show me unread WhatsApp leads from this morning.” “Draft a reply for Alex.” “Summarise yesterday's support tickets.” Whatever you can describe, Claude can do.

3

Claude does the work, you approve

Claude shows you what it's about to do — and waits for your OK. Nothing happens on your WhatsApp without your green light. Full transparency, zero surprises.

4 skills

What Claude can do, once connected.

Four simple skills cover most day-to-day inbox work. You ask in plain English — Claude picks the right one.

Read your unread chats

Claude can list the latest unread conversations — who sent them, the last message and when — filtered by label, agent or channel.

Send a reply

Claude drafts and sends messages — text, media, buttons or pre-approved templates. You can require a confirmation before anything goes out.

Find a contact

Look up anyone by name, phone, label or custom field. Claude pulls the profile and recent chat history, perfect for "find the customer who…" questions.

Trigger an automation

Run a Flow you already built — welcome sequences, lead qualification, handoffs, reminders. Claude can fire them on demand or on a schedule.

Setup

Live in 5 minutes.

Three clicks to read your first WhatsApp message from Claude. No installs, no code, no technical setup.

Talk to your inbox

Once the custom MCP is connected, open any Claude conversation and ask: "show my unread WhatsApp leads", "reply to Maria with the proposal" or "schedule a follow-up tomorrow." Claude asks before sending anything.
