I Built an AI Voice Receptionist with Vapi and n8n MCP (free template)

Tavsif:

I built a full AI voice receptionist using VAPI on the front‑end and n8n on the back‑end, powered by an n8n MCP server that connects to seven n8n workflows. In this video, I walk through the entire system from scratch and show how the agent gathers info, manages the CRM, books and updates appointments, transfers calls, answers questions, logs every call, and keeps an appointment history. Everything is built with no code and designed to be easy to customize for your own use case. By the end, you’ll understand the full setup and have everything you need to launch your own AI receptionist. 00:00 Live Demo 06:00 Voice AI Transparency 06:32 High Level Breakdown & Wireframe 10:33 Vapi Model Configuration 11:49 n8n MCP Tool 13:30 Client Lookup and New Client 15:30 Setting up Vapi to ‘Call’ n8n 18:00 Check Availability and Book Appointment 21:30 Update Appointment and Delete Appointment 23:30 Handoff and Transfer Call 25:33 Knowledge Base Files 27:22 Why n8n MCP? 28:50 Logging Call Summaries 32:13 Setting up Phone Numbers 32:57 Get the FREE Resources 33:35 Want to Master AI Automations?
