We have been hard at work making sure that the Firebase MCP server works really well with not only the Gemini CLI, but all the places that you may want to use an MCP server. This includes Google’s newest release, the Antigravity IDE. Let’s take a look at how to add the Firebase MCP server to Antigravity and what Antigravity can do with our MCP server.

Adding Firebase MCP to Antigravity

To add the Firebase MCP server, open Antigravity and go to the drop-down menu in the Agent window. Select “MCP servers”, then choose Firebase from the list of available MCP servers. This will open a description of the MCP server, where you can click install to add our Firebase MCP server.

Link your current app to Firebase

To get started, tell the agent to initialize Firebase in your current project. The agent will then develop an implementation plan using the MCP server to link Firebase to your project. If the agent needs more information to complete a task, it will pause and ask for your input. Once the task is complete, Antigravity provides a walkthrough of the steps it took to link Firebase to your app.

Ask Antigravity to build your app

Using Antigravity we can then specify a series of steps that we want the agent to take in building our app. I prompted a racing game that incorporated sign in using email and password login from Firebase and Cloud Firestore for a leaderboard. Antigravity, using its suite of MCP tools from the Firebase MCP server, fetched the API keys for my web app, so I didn’t need to visit the Firebase console, and implemented both features without issue.

I then went to test out the game and it worked as I expected.

Deploy the app with Firebase Hosting

The Antigravity agent already has access to Firebase Hosting via the Firebase MCP server. The agent understands can consult with the Firebase MCP server to verify the steps to deploy to Firebase Hosting. The agent makes a deployment plan which includes compiling the code and then running the firebase deploy --only hosting command to get the app onto Firebase Hosting. We don’t need to run any commands ourselves other than asking the agent to deploy for us. Once this is done, we can share the game we built with our friends!

The Firebase MCP server also supports App Hosting, which is optimized for server-rendered Next.js and Angular web apps.

Conclusion

Accelerate your app development with Antigravity and the Firebase MCP server. Come tell us on X and LinkedIn how you are using Firebase with Antigravity, we cannot wait to see what you build next!
