Gemini CLI just got even more incredible with this massive new upgrade from Google.
Now with Extensions, you can connect Gemini CLI straight to your favorite tools— Nano Banana, BigQuery, Genkit, anything —and use them without ever leaving the terminal.
Just look how we easily wrote several Postman tests for our APIs right from Gemini CLI -- nothing but a single prompt:
[demo: automating API tests with the Gemini CLI Postman extension]
They were all there for us to run at any time:

Extensions are like plugins for Gemini CLI -- built with MCP servers.
With Gemini CLI Extensions you can install integrations with a single command and manage them easily -- and even build your own.
They teach the AI how to work with specific tools, APIs, or services, so it can generate code, run commands, and answer questions with context.
And there are boatloads to choose from -- with many more on the way — both official and from the community.
For example you could install a BigQuery extension that lets Gemini write SQL for your datasets, or a Genkit extension that scaffolds app logic and helps debug workflows.
Installing an extension is easy:
gemini extensions install https://github.com/gemini-cli-extensions/securityYou can also list, enable, or disable extensions like this:
gemini extensions list
gemini extensions disable security
gemini extensions enable securityEach extension includes a simple manifest file (gemini-extension.json) that tells Gemini how to use the tools it exposes. If something’s wrong with the manifest, Gemini CLI will flag the issue immediately so you can fix it.
