The MIT-licensed CLI for testing, managing, and deploying Firebase projects, and the home of the official Firebase MCP Server. Run firebase init to scaffold a firebase.json, firebase deploy to ship Hosting, Functions, Firestore, and rules, and firebase emulators:start to run services locally without touching live data. It supports service-account and application-default credentials, making it fully compatible with CI and headless environments.
