Firebase MCP Server — Hosted Api Connectors Integration

mcp-firebase — Firebase MCP Server

Read and write Firestore documents, manage Auth users, and send push notifications.

Firebase is Google's app development platform powering millions of mobile and web apps. This MCP server covers three of its most-used services: Firestore (document database), Firebase Auth (user management), and FCM (push notifications) — letting your AI agents read live app data, manage user accounts, and push notifications directly without touching your app's backend code.

Live endpoint: https://mcp.aerostack.dev/s/aerostack/mcp-firebase

What You Can Do

• Query and update Firestore documents and collections — great for agents that need to read or modify your app's live data
• List, create, or disable Firebase Auth users to handle account management requests from support workflows
• Send targeted push notifications to individual devices or multicast to up to 500 tokens at once from automation pipelines
• Run complex Firestore queries with field filters to find documents matching specific criteria
