# Wati — how to use (mcp.ai)

Connect your Wati account and use 5 tools for marketing automation straight from your AI agent. Connect with your own API key. Wati is a WhatsApp Business API platform that automates marketing, sales, service, and support.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_wati?ms=1787295900000`
Add it as a custom/remote MCP connector in your client (Claude, Cursor, VS Code…), then authenticate when prompted. Once connected, ask the agent to use the server's tools (e.g. `wati_add_contact`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/wati`
Auth: `Authorization: Bearer sk_live_…` — create a workspace API key at https://mcp.ai/settings/api-keys
