# Build on a real WhatsApp account

One workspace, two ways in. Both use the same accounts, the same plan and the same API keys — pick the one that fits the caller.

[

## 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 36 tools — send and read messages, contacts, groups, channels, calls and webhooks.

## REST API

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.
