2Chat MCP

The 2Chat MCP server lets any AI assistant (Claude, Cursor or any other MCP-Compatible client) send messages to WhatsApp (using your connected number to 2Chat), manage your WhatsApp Business Templates, manage contacts, etc.

Authentication

All requests use your 2Chat API key as an HTTP header:
