# Connect your AI client to WhatsApp

WhatsMCP is a hosted Model Context Protocol server. Point any MCP-capable client at one endpoint, sign in once, and your agent can send, read and manage a real WhatsApp number — Personal or Business (official). Pick your client below for step-by-step setup.

One endpoint: `https://api.whatsmcp.com/mcp`

How it works

## One remote server, every client.

Every guide ends at the same place: a remote Streamable-HTTP MCP server at `https://api.whatsmcp.com/mcp` . The api. host and the `/mcp` path both matter — the bare domain is the most common mistake.

-   OAuth by default — the client reads the server metadata, registers itself and sends you to the console to approve. Nothing is pasted or stored.
-   API key fallback — a `wamcp_live_…` key over `Authorization: Bearer` , or `x-api-key` where a client reserves Authorization, for CLIs and CI.
-   Connect a number once — pair a Personal number by QR, or connect a [Business (official)](https://whatsmcp.com/whatsapp-business-api) Cloud API number from the console. One connector serves both.

## Give your agent a number.
