WhatsMCP puts a WhatsApp number to work: link a Personal number as a device, or connect a Business (official) number through Meta’s Cloud API. Give an AI agent the number’s chats over MCP, or bridge a Personal number’s calls to your PBX over SIP.
Both run on the same number and the same console, on that number's one plan: pick a plan with calls when you want them on SIP. A Business (official) number's plan includes a hosted line for its WhatsApp calls; it calls a customer once they allow it, and Meta bills those calls by the minute.
For AI agents
A hosted Model Context Protocol server. Claude, ChatGPT or your own agent connects to one URL and works the number like a person would.
For phone systems
Two-way calling between WhatsApp and SIP. WhatsApp calls ring your PBX or a hosted line, and your extensions call out as the same number.
For a Personal number: no Meta Business verification, no message templates, no new number. You link a WhatsApp account once, then choose what it does.
Running a business line? Connect a Business (official) number through Meta’s WhatsApp Cloud API instead — with message templates, and within Meta’s terms.
Scan a code with WhatsApp on your phone, the way you would link WhatsApp Web. The number joins as a linked device.
The phone stays the primary device and keeps its chats. Nothing to re-register, no new number to announce.
Through our network by default, or through a WireGuard tunnel or SOCKS5 proxy you run, set per number.
Messages and calls for each number, in the console and through the API, with webhooks for what is new.

A service that puts a WhatsApp number to work, Personal or Business (official), in two ways: an MCP server that lets AI agents read and send its messages, and a SIP trunk that bridges its calls to a phone system in both directions.
It can be either. A Personal number links as a linked device, the way WhatsApp Web does: no Meta Business verification and no message templates. A Business (official) number connects through Meta’s WhatsApp Cloud API with Connect with Facebook: official, with message templates, and Meta’s own per-message pricing. WhatsMCP is not affiliated with Meta.
For a Personal number, yes: the same number, the same console, one plan — pick a plan with calls when you want them on SIP. A Business (official) number’s plan includes the MCP Server and a hosted line for its WhatsApp calls, which calls a customer once they allow it.
With a Personal number, yes: the phone stays the primary device and keeps its chats, and WhatsMCP joins alongside it as a linked device. A Business (official) number runs on Meta’s Cloud API instead of the WhatsApp app.
There is a free plan and flat monthly paid plans, one per number; the plans with calls have no per-minute billing. Current prices are on the plans page.
WhatsMCP is not affiliated with or endorsed by Meta. A Personal number connects to WhatsApp directly, as a linked device, and that falls outside WhatsApp’s terms of service, so WhatsApp may restrict a number it sees as misused. We suggest starting with a number you can spare and keeping traffic personal — no bulk or unsolicited messages. A Business (official) number connects through Meta’s WhatsApp Cloud API instead: the officially supported route.
Link a number, pick a plan, connect an agent or a phone.
