How It Works
WhatsApp (phone) <──Baileys──> MCP Server <──stdio──> Claude Code
- The MCP server connects to WhatsApp as a linked device using the Baileys library (same protocol as WhatsApp Web)
- Incoming messages are forwarded to your Claude Code session as channel notifications
- Claude responds using MCP tools (
reply, react, edit_message, download_attachment)
- Access control ensures only allowlisted contacts can interact
Messages sent by Claude appear as coming from your phone number. Use a dedicated number if you need a separate bot identity.
Use Cases
- Personal AI assistant — message Claude from anywhere via WhatsApp, get answers, run code, and manage tasks on the go
- Team support bot — add Claude to a WhatsApp group with custom personality and let it help your team
- Remote development — approve Claude's tool requests and monitor progress from WhatsApp when away from your desk
- Automated notifications — use cron tasks to send scheduled reports or reminders through WhatsApp
- Multi-account management — run separate personal and business WhatsApp accounts with different Claude behaviors
FAQ
Q: Do I need a WhatsApp Business API account?
A: No. This plugin connects as a linked device to your regular WhatsApp account—no Business API, no Meta developer account, no API keys needed.
Q: Can people tell it's AI responding?
A: No, messages come from your phone number. Recipients see no difference. Use a separate number if you want a distinct bot identity.
Q: Does it work when my phone is off?
A: Yes. WhatsApp linked devices work independently once paired. Your Claude Code session must stay open though.
Q: Is my data sent to third parties?
A: No. The MCP server runs locally on your machine. Messages go directly between WhatsApp and your local Claude Code session.
Q: What happens if Claude Code disconnects?
A: The WhatsApp session disconnects too. Just relaunch—no re-pairing needed, auth is saved locally.
