## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Firebase MCP or direct API to discover projects, sign up users, sign in users, and refresh Secure Token sessions through natural language.

## Summary

Firebase is Google's app development platform for authentication, apps, and backend services.
It helps teams ship secure user sign-in and account flows without building auth from scratch.

## Categories

- developer tools & devops

## Toolkit Details

- Tools: 8

## Images

- Logo: https://logos.composio.dev/api/firebase

## Authentication

- **Api Key**
  - Type: `api_key`
  - Description: Api Key authentication for Firebase.
  - Setup:
    - Configure Api Key credentials for Firebase.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

- Sign up a new Firebase user
- Refresh an expired Firebase ID token
- Send password reset email to user

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `FIREBASE_DISCOVER_SIGN_IN_METHODS` | Discover Sign-In Methods | Look up sign-in methods previously used by a Firebase account email. Firebase anti-enumeration settings can suppress results, so empty lists or an absent registered value do not prove that the account does not exist. |
| `FIREBASE_GET_AUTH_PROJECT_CONFIG` | Get Auth Project Config | Get the public Firebase Authentication configuration associated with the connected Web API key, including the project ID and authorized domains. This does not authenticate a user or grant backend access. |
| `FIREBASE_REFRESH_ID_TOKEN` | Refresh ID Token | Exchange a Firebase refresh token for a fresh Firebase ID token and rotated refresh token using Google's Secure Token service. |
| `FIREBASE_SIGN_IN_WITH_CUSTOM_TOKEN` | Sign In With Custom Token | Exchange a trusted server-minted Firebase custom token for a Firebase ID token and refresh token. The exchange may create the Firebase user on their first sign-in. |
| `FIREBASE_SIGN_IN_WITH_EMAIL_LINK` | Sign In With Email Link | Complete Firebase email-link sign-in using an email address and the one-time OOB code from a previously delivered sign-in link. This may create the Firebase user on first sign-in; it does not send email. |
| `FIREBASE_SIGN_IN_WITH_IDP` | Sign In With Identity Provider | Sign in with one configured external identity provider using provider-specific OAuth or OIDC credential parameters. This sign-in-only tool may create the Firebase user on first sign-in and rejects Firebase idToken account-linking semantics. |
| `FIREBASE_SIGN_IN_WITH_PASSWORD` | Sign In With Password | Sign in an existing Firebase Authentication user with email and password and return fresh ID and refresh tokens. Requires the Email/Password provider to be enabled. |
| `FIREBASE_VERIFY_PASSWORD_RESET_CODE` | Verify Password Reset Code | Validate a Firebase password-reset OOB code and identify the associated email and request type without changing the password. |

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
    },
  },
});

const tools = await client.tools();
const { text } = await generateText({

## Why Use Composio?

### 1. AI Native Firebase Integration

- Supports both Firebase MCP and direct API based integrations
- Structured, LLM-friendly schemas for reliable Firebase Auth tool execution
- Rich coverage for project discovery, user sign-up, sign-in, out-of-band codes, and token refresh flows

### 2. Managed Auth

- Store Firebase Web API keys securely instead of hard-coding them into agent prompts or app code
- Central place to manage, scope, and revoke Firebase access across users and environments
- Per user and per environment credentials so your agents can act safely in the right Firebase project

### 3. Agent Optimized Design

- Firebase tools are designed so agents can understand the right auth flow to use, from sign-up to token refresh
- Tools are tuned using real error and success rates to improve reliability over time
- Comprehensive execution logs so you always know which Firebase action ran, when, and on whose behalf

### 4. Enterprise Grade Security

- Fine-grained RBAC so you control which agents and users can access Firebase tools
- Scoped, least privilege access to Firebase Authentication workflows
- Full audit trail of agent actions to support review, debugging, and compliance
