Connect

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) Cloud API number from the console. One connector serves both.

Give your agent a number.
