Firebase MCP Server

Firebase MCP Server

Connect Claude to your Firebase project through Firebase's official MCP Server.

The Firebase MCP Server enables Claude to interact with Firestore databases, Firebase Authentication, Cloud Functions, Hosting, Storage, and other Firebase services using natural language commands.

What Can Claude Do with the Firebase MCP Server?

The Firebase MCP Server exposes Firebase service functionality to Claude through the Model Context Protocol.

Core capabilities:

• Firestore and Data Connect Access — Read and write documents, query collections, and manage database data
• Authentication Management — Access user information, manage auth states, and query user records
• Cloud Functions — Interact with deployed functions and view function logs
• Hosting and Storage — Manage deployed sites and access Cloud Storage resources
• Security-Rule-Aware Assistance — Work with Firebase security rules and configurations
• Project Operations — View Firebase project configuration and service status

Access scope: Claude can access Firebase services based on your Firebase CLI authentication and project permissions. The integration respects Firebase security rules and IAM permissions.

How to Install the Firebase MCP Server

Firebase provides an official MCP Server through Firebase Tools.

For Claude Code (Recommended)

Option 1: Plugin Marketplace

claude plugin marketplace add firebase/firebase-tools
claude plugin install firebase@firebase

Option 2: Manual MCP Setup

claude mcp add firebase npx -- -y firebase-tools@latest mcp

Both methods connect Claude to the official Firebase MCP Server.

For Claude Desktop

Add the Firebase MCP Server to your claude_desktop_config.json file:

Configuration file locations:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Configuration structure:

{
  "mcpServers": {
    "firebase": {
      "command": "npx",
      "args": ["-y", "firebase-tools@latest", "mcp"]
    }
  }
}

Restart Claude Desktop after saving the configuration file.

Firebase MCP Authentication

The Firebase MCP Server uses the same credentials as your authorized Firebase CLI environment.

Authentication methods:

1. Firebase CLI Session (Default)

• Run firebase login in your terminal
• Your authenticated session is used by the MCP Server
• No additional credential setup required

1. Runtime Environment Credentials

• In CI/CD or server environments, Firebase CLI uses Application Default Credentials (ADC)
• Service accounts or other environment-specific auth can apply

1. Advanced: Service Account Configuration

• For specific deployment scenarios, service accounts can be configured
• This is an advanced option, not the default setup path

Typical setup:

Most users authenticate with firebase login before using the MCP Server. This provides access to all Firebase projects your account can access.

Firebase MCP Use Cases & Examples

Example workflows that become possible with the Firebase MCP Server.

Query Firestore Documents

Example prompt:

> "Show me all documents in the 'users' collection where status is 'active'."

Claude can query Firestore collections with filtering criteria.

Create Firestore Documents

Example prompt:

> "Add a new document to the 'posts' collection with title 'New Article', author 'John Doe', and published set to true."

Claude can create documents in Firestore collections.

Manage Authentication Users

Example prompt:

> "List all users who signed up in the last 7 days."

Claude can query Firebase Authentication user records.

View Cloud Functions

Example prompt:

> "Show me the status and recent logs for my deployed Cloud Functions."

Claude can access function deployment information and execution logs.

Check Security Rules

Example prompt:

> "What are the current Firestore security rules for the 'posts' collection?"

Claude can retrieve and display security rule configurations.

Note: These are example use cases. Actual capabilities depend on your Firebase project configuration, security rules, and the MCP server's exposed toolset.

Use Firebase MCP in Verdent

Verdent provides streamlined Firebase integration with simplified authentication. This is Verdent's platform-level integration flow, not the default setup path from Firebase's official documentation.

Connect your Firebase project once and access Firestore, Auth, and other services across all Verdent projects without manual CLI configuration.
