Green API WhatsApp MCP: WhatsApp messaging from your AI app

Send WhatsApp messages, look up contacts, manage groups and look after your Green API instance from an AI app. Green API WhatsApp's MCP gateway exposes all of that, and ContextGate sits in front of it: switch off sending so your AI app can't message anyone, or have a policy warn first, and every call is kept in Activity.
