🚀 WhatsApp Desktop MCP & Headless AI CRM Companion

An all-in-one local desktop companion that connects your WhatsApp Web directly to Google Gemini, Claude, Cursor, and other AI tools over the Model Context Protocol (MCP). Features an invisible local AI CRM with automated pipeline tracking and a human-in-the-loop "Draft & Approve" workflow.

✨ Features

• 📱 Zero API Key Setup: Uses an embedded PyWebView browser wrapper to log in to WhatsApp Web directly. No Meta Cloud API setup or paid developer keys required!

• 🤖 Headless AI CRM: Automatically tracks contacts, tags, and deal stages (Lead -> Negotiating -> Won) in a local, private JSON database (crm.json).

• ✍️ Draft & Approve Workflow: AI can draft intelligent responses directly inside your WhatsApp Web chat input box without hitting send. You retain 100% control to review and approve with one click.

• ⚡ High Context Density: The read_chats tool automatically attaches CRM tags, notes, and pipeline stages in one single request—minimizing tool calling overhead.

• 🌐 Remote Tunnel Integration: Built-in ngrok tunneling for connecting external AI models securely via HTTPS / Server-Sent Events (SSE).

• 🔒 100% Local & Private: All session cookies, message logs, and CRM data remain strictly on your local computer (.wa_session/).
