Whatsapp MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 68 installs a week from npm. Last commit 15 Jun 2026.
WhatsApp MCP Server - Human-in-the-loop for AI agents via WhatsApp
Today is the operative word: we check Whatsapp MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
claude mcp add whatsapp-mcp -- npx -y @mhrj/whatsapp-mcp
{
"mcpServers": {
"whatsapp-mcp": {
"args": [
"-y",
"@mhrj/whatsapp-mcp"
],
"command": "npx"
}
}
}
[mcp_servers.whatsapp-mcp]
command = "npx"
args = ["-y", "@mhrj/whatsapp-mcp"]
{
"mcpServers": {
"whatsapp-mcp": {
