The Firebase MCP server is built into the Firebase CLI and lets Claude set up projects, work with Firestore and Auth, and deploy apps using the same login as the CLI. Its tools are grouped by product, from Crashlytics and Remote Config to Cloud Messaging, and you can load only the groups you need.

Who it is for

App builders who use Firebase as a backend
Mobile and web developers
Makers shipping prototypes with Claude Code

Prompts to try

Once it is connected, ask in plain words. Claude decides when to use the server and asks before it changes anything important.

Prompt 1

Set up Firebase Hosting and Firestore for this project, then deploy it.

Prompt 2

Show me the top Crashlytics crashes in my Android app from the last seven days.

Prompt 3

Find the Firestore documents in the orders collection where status is pending.

How to connect it

In Claude Code

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

In the Claude desktop app

Add this to claude_desktop_config.json, then restart the app:

json

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

Good to know

Sign in with firebase login (or use Application Default Credentials) first; the --only flag limits which tool groups load.
