vapi cli copy page overview the vapi cli is the official command line interface that brings world class developer experience to your terminal and ide build test and deploy voice ai applications without leaving your development environment in this guide you ll learn to install and authenticate with the vapi cli initialize vapi in existing projects manage assistants phone numbers and workflows from your terminal forward webhooks to your local development server turn your ide into a vapi expert with mcp integration installation install the vapi cli in seconds with our automated scripts macos linux windows docker curl ssl https vapi ai install sh bash quick start 1 authenticate connect your vapi account vapi login this opens your browser for secure oauth authentication 2 initialize your project add vapi to an existing project vapi init the cli auto detects your tech stack and sets up everything you need 3 create your first assistant build a voice assistant vapi assistant create follow the interactive prompts to configure your assistant key features project integration drop vapi into any existing codebase with intelligent auto detection vapi init detected next js application installed vapi ai web sdk generated components vapibutton tsx created pages api vapi webhook ts added environment template supports react vue next js python go flutter react native and dozens more frameworks mcp integration turn your ide into a vapi expert with model context protocol vapi mcp setup your ide s ai assistant cursor windsurf vscode gains complete accurate knowledge of vapi s apis and best practices no more hallucinated code or outdated examples local webhook testing forward webhooks to your local server for debugging terminal 1 create tunnel e g with ngrok ngrok http 4242 terminal 2 forward webhooks vapi listen forward to localhost 3000 webhook important vapi listen is a local forwarder only it does not provide a public url you need a separate tunneling service like ngrok to expose the cli s port to the internet update your webhook urls in vapi to use the tunnel s public url multi account management switch between organizations and environments seamlessly list all authenticated accounts vapi auth status switch between accounts vapi auth switch production add another account vapi auth login complete feature parity everything you can do in the dashboard now
