Provides tools for querying live Firebase projects, including Firestore database management (listing collections, subcollections, and documents) and accessing Cloud Function logs with filtering capabilities.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Firebase Live MCP Servershow me the last 10 error logs for the 'sendEmail' function"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Firebase Live MCP Server
MCP server for querying live Firebase projects - Firestore and Cloud Function logs.
Setup
npm install
npm run buildRelated MCP server: FireMCP
Authentication
Uses Application Default Credentials. Run:
gcloud auth application-default loginProject Detection
The server auto-detects the Firebase project from .firebaserc in the current working directory.
Override with env var:
FIREBASE_PROJECT_ID=my-projectUsage with Claude Desktop
Add to claude_desktop_config.json:
{
"mcpServers": {
"firebase-live": {
"command": "node",
"args": ["/Users/nigelthorne/code/firebase_live_mcp_server/dist/index.js"],
"cwd": "/path/to/your/firebase/project",
"env": {
"FIREBASE_PROJECT_ID": "optional-override"
}
}
}
}The cwd should point to a directory with .firebaserc for auto-detection.
