Build on a real WhatsApp account
One workspace, four ways to use it. The MCP server, REST API and SIP trunk share the same accounts, plan and API keys; AI agents run on your numbers straight from the console.
MCP server
https://api.whatsmcp.com/mcp
For AI agents: Claude, ChatGPT, Cursor and any client that speaks MCP. Sign in with OAuth or use an API key; all 46 tools — messages, templates, contacts, groups, channels, calls and webhooks, for Personal and Business (official) numbers.

https://api.whatsmcp.com/v1
For scripts, backends and CRMs: plain HTTP and JSON with an API key, an OpenAPI 3.1 spec and an interactive reference. Starts with accounts and messages; more endpoints are on the way.

sip.whatsmcp.com
For phone systems: take WhatsApp calls on your PBX or a hosted SIP line and dial WhatsApp numbers as your own. Two-way calling, G.722 or G.711, flat monthly per number — no per-minute fees.

console.whatsmcp.com
No code: build an AI agent in the console, bring your own LLM key, ground it in a knowledge base, and let it answer your WhatsApp chats — handing any conversation to a person when you step in.
