## What it does

This server provides development assistants with direct access to your Firebase projects using standard I/O. It queries documents in Cloud Firestore and Realtime Database. It also updates user records in Firebase Authentication. Setup stays minimal.

The tool executes commands using credentials from your local Firebase CLI configuration. If your CLI environment is not authenticated, tool calls fail immediately. You will need Node.js with npm on your machine.

## Requirements
- Needs: Node.js (commands run via npx)
