Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account firebase for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP server that gives an AI assistant Firebase project, database, auth, messaging, Crashlytics and deployment capabilities through the Firebase CLI.

What you can do: Create, list and inspect Firebase projects, apps and environment settings, and sign in or out of the CLI session. Read, query, write and delete Firestore documents, and read or write Realtime Database paths. Retrieve and update Auth users, and send Cloud Messaging push notifications to tokens or topics. Validate and fetch security rules, and build or execute Firebase SQL Connect schemas and queries. Inspect Crashlytics issues, events and reports, read Cloud Functions and App Hosting logs, and manage Remote Config templates.
When to use it: Useful when an assistant is working inside a Firebase-backed app and should inspect or change projects, data, auth users, rules or deployment state without switching to the console or CLI by hand.
Requirements: Node.js and npm; runs locally via npx firebase-tools. It uses the same user credentials that authorize the Firebase CLI in the environment where it runs, so a Firebase login with access to the target projects is needed. Desktop MCP clients only.

Before you install

Many tools write or delete: Firestore documents, Realtime Database data, Auth users and claims, Remote Config templates, Crashlytics notes and issue state, and push notifications. It acts with the CLI's logged-in credentials, so scope the account carefully. Some features use Gemini in Firebase, whose output may be inaccurate; the README warns against entering PII or user data and against using untested generated code in production.

Installation

In SourceWeft

Open Firebase Mcp in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

Firebase MCP Server

[License] [Install MCP Server]

The Firebase Model Context Protocol (MCP) Server gives AI-powered development tools the ability to work with your Firebase projects and your app's codebase. The Firebase MCP server works with any tool that can act as an MCP client, including: Firebase Studio, Gemini CLI, Claude Code, Cline, Cursor, VS Code Copilot, Windsurf, and more!

Features

An editor configured to use the Firebase MCP server can use its AI capabilities to help you:

Create and manage Firebase projects - Initialize new projects, list existing ones, and manage Firebase apps
Manage Firebase Authentication users - Retrieve, update, and manage user accounts
Work with Cloud Firestore and Firebase SQL Connect - Query, read, write, and manage database documents
Retrieve Firebase SQL Connect schemas - Generate schemas and operations with AI assistance
Understand security rules - Validate and retrieve security rules for Firestore, Cloud Storage, and Realtime Database
Send messages with Firebase Cloud Messaging - Send push notifications to devices and topics
Access Crashlytics data - Debug issues, view crash reports, and manage crash analytics
Deploy to App Hosting - Monitor backends and retrieve logs
Work with Realtime Database - Read and write data in real-time
Query Cloud Functions logs - Retrieve and analyze function execution logs
Manage Remote Config - Get and update remote configuration templates

Some tools use Gemini in Firebase to help you:

Generate Firebase SQL Connect schema and operations
Consult Gemini about Firebase products

Important: Gemini in Firebase can generate output that seems plausible but is factually incorrect. It may respond with inaccurate information that doesn't represent Google's views. Validate all output from Gemini before you use it and don't use untested generated code in production. Don't enter personally-identifiable information (PII) or user data into the chat.

Installation and Setup

Prerequisites

Make sure you have a working installation of Node.js and npm.

Basic Configuration

The Firebase MCP server can work with any MCP client that supports standard I/O (stdio) as the transport medium. When the Firebase MCP server makes tool calls, it uses the same user credentials that authorize the Firebase CLI in the environment where it's running.

Here are configuration instructions for popular AI-assistive tools:

Gemini CLI

Install the Firebase extension for Gemini CLI:

Claude Code

Option 1: Install via plugin (Recommended)

The easiest way to set up the Firebase MCP server in Claude Code is to install the official Firebase plugin:

Add the Firebase marketplace for Claude plugins:

Install the Claude plugin for Firebase:

Verify the installation:
bash
```
claude plugin
```
```
claude plugin
```

Option 2: Configure MCP server manually

Alternatively, you can manually configure the Firebase MCP server by running:

You can verify the installation by running:

It should show:

Cursor

Add to .cursorrules in your project directory or configure in Cursor settings:

json

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

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

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

json

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

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

Firebase Studio

To configure Firebase Studio to use the Firebase MCP server, edit or create the configuration file: .idx/mcp.json

json

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

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

Usage

Once configured, the MCP server will automatically provide Firebase capabilities to your AI assistant. You can:

Ask the AI to help set up Firebase services
Query your Firestore database
Manage authentication users
Deploy to Firebase Hosting
Debug Crashlytics issues
And much more!
