About Firebase MCP

Google's local Firebase CLI MCP server lets AI development clients inspect and manage Firebase projects and app configuration, with additional product-specific tools, prompts, and resources.

What you can use it for

  • Inspect Firebase project configuration and SDK settings
  • Work with Firestore, Authentication, Storage, and other enabled Firebase products
  • Generate or validate security rules and investigate Crashlytics issues
Connection and setup
Hosting
Local; some tools proxy to Firebase-hosted backends
Transport
stdio
Endpoint
Local process; no hosted endpoint documented
Authentication
Sign in through Firebase CLI with firebase login; tools require authenticated access, and some operations require a selected Firebase project. Google Cloud/Firebase permissions still apply.

Requirements

  • Node.js and npm for npx setup
  • Firebase CLI authentication
  • A Firebase/Google Cloud project for project-specific operations
  • Appropriate IAM/project permissions

Setup steps

  1. Add command npx with arguments -y, firebase-tools@latest, mcp.
  2. Sign in with firebase login (Firebase Studio documents firebase login --no-localhost for its terminal flow).
  3. Select or initialize the intended project; review the active project before requesting changes.
  4. Inspect tool list and permissions. Start with a read-only request such as firebase_get_environment or firebase_list_projects. Obtain explicit confirmation before initialization, security-rule changes, or deployment.

This server’s available tools can vary by account, permissions, or configuration. The list shown is not its full runtime catalog.

Limitations and notes
  • The server has tools capable of creating projects, modifying users/configuration, initializing services, and deploying; review exact effects and obtain user approval for external changes.
  • Some Firebase product tools proxy requests to remote services even though the MCP process runs locally.
  • Tool availability depends on CLI version, Firebase products, authentication, and project permissions.
