Firebase MCP

Overview

• Firestore: Document database operations

• Storage: File management with robust upload capabilities

• Authentication: User management and verification

Quick Start

Prerequisites

• Firebase project with service account credentials

• Node.js environment

1. Install MCP Server

• Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json

• Augment: ~/Library/Application Support/Code/User/settings.json

• Cursor: [project root]/.cursor/mcp.json

Configure for npx (recommended)

Configure for local installation

2. Test the Installation

Latest Features: Storage Upload (v1.3.3)

• `storage_upload`: Upload files from text, base64 content, or local file paths

• `storage_upload_from_url`: Import files directly from external URLs

Key Benefits

• Permanent Public URLs: All uploads generate non-expiring public URLs

• Content Type Detection: Automatic detection from file extensions and data

• Multiple Upload Methods: Flexible options for different use cases

• Rich Response Formatting: Clear, well-structured upload confirmations

Upload Methods

1. Local File Path (Recommended for all file types)

2. Base64 Data URL (For smaller files)

3. Plain Text (For text files)

4. External URL (Using storage_upload_from_url)

Important: For binary files like images and PDFs, always use the direct file path method for best reliability.

Setup & Configuration

1. Firebase Configuration

1. Go to Firebase Console Project Settings Service Accounts

2. Click "Generate new private key"

3. Save the JSON file securely

2. Environment Variables
