What you can do with the Firebase MCP server

Ask your agent in plain language. Each of these maps to a real tool on the server.

  • Use the manage cloud storage tool in Firebase
  • Use the lookup user tool in Firebase
  • Use the send push notification tool in Firebase
  • Use the list users tool in Firebase
  • Use the update remote config tool in Firebase
  • Use the manage firestore document tool in Firebase

How teams use Firebase with agents

Firebase runs the backend of many mobile and web apps. The integration lets an agent query Firestore, read and update Realtime Database paths, manage users, change Remote Config and send push notifications.

Support lookups

Look up a user by email and read their Firestore document to answer a support question.

Feature flags

Read Remote Config and change a parameter to roll a feature out to more users.

Push notifications

Send a notification to a device or a topic, such as a status update during an incident.

Data fixes

Query Firestore for broken records and update them with a reviewed change.

Tools to start with

  • Query Firestore: Filtered queries over a collection.
  • Update Remote Config: Changes flags without an app release.
  • Send Push Notification: Messages to devices or topics.

Sign-in and permissions

Firebase accepts Google OAuth or a service account key from the Firebase project settings. A service account key has admin access to the project, so keep it for trusted automations and give people OAuth instead.

Sign-in options on Metorial: Google OAuth, Service Account Key.

Supported Tools

manage_storage

Manage Cloud Storage

List, upload, get metadata, delete, or copy objects in Firebase Cloud Storage. Supports prefix-based listing for browsing folder-like structures, fetching download URLs, and copying objects between paths.

manage_user

Manage User

Create, update, delete, or retrieve a Firebase Authentication user. Supports managing user properties including email, password, display name, phone number, photo, email verification status, and account disabled state.

get_firebase_apps

Get Firebase Apps

List Firebase Android, iOS, and Web apps in a project, retrieve a specific app, or download its SDK configuration artifact. Use this to discover app IDs, package or bundle identifiers, web config, and native google-services files.

Connect Firebase to your AI client

Every client uses the same Magic MCP URL, and so does any other MCP client. Add it once and sign in with SSO.

  1. Enable Firebase in Metorial. In your Metorial portal, enable the Firebase MCP server and sign in with the account that owns the data. Access stays governed by your team policies.
  2. Add a custom connector. Open Customize, then Connectors. Select Add, then Custom, then Web.
  3. Paste your Metorial MCP URL. Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>) and continue.
  4. Sign in. Select Add and sign in to load Firebase tools.

Run Firebase through the Metorial gateway

One governed layer for every app your agents reach, not a separate connector per tool.

  • Give Firebase and every other app to your whole team through one MCP gateway, behind your SSO.
  • Scope which teams and agents can use Firebase tools with role-based access control, and trace every call.
  • Prefer to run it yourself? Metorial is open source and self-hostable.
