October 8, 2025 — Google today announced the launch of Gemini CLI Extensions, a new framework that allows developers to customize and extend Gemini CLI, Google’s open-source, AI-powered command-line agent. The new feature enables developers to connect Gemini directly to their favorite tools and platforms, bringing a new level of intelligence and flexibility to terminal-based workflows.

In just three months since launch, over one million developers have adopted Gemini CLI. With the introduction of extensions, developers can now tailor the Gemini experience to their unique environments and daily workflows — without leaving the terminal.

A Smarter, More Personalized Command Line

Gemini CLI Extensions transform Gemini from a standalone AI assistant into a fully customizable ecosystem. Each extension functions as a power-up, connecting Gemini to external tools — from CI/CD pipelines and design systems to databases and payment APIs.

Every extension includes a built-in “playbook” that teaches the AI how to use the new tool effectively. This allows developers to get instant, meaningful results with no manual configuration.

Installing an extension is simple:

gemini extensions install <GitHub URL or local path>

The result is a smarter, more capable command-line environment that adapts to the developer — not the other way around.

An Open Ecosystem of Tools and Partners

At launch, Gemini CLI Extensions include integrations from Google and an array of leading technology partners and open-source contributors.

Early launch partners include:

• Dynatrace – Real-time application monitoring and root-cause insights.

• Elastic – Query and analyze Elasticsearch data in agentic workflows.

• Figma – Sync design assets and generate code directly from frames.

• Harness – Use AI to optimize CI/CD pipelines and detect issues.

• Postman – Manage APIs and collections with natural language commands.

• Shopify – Explore APIs, build serverless functions, and query documentation.

• Snyk – Embed security scanning into your development flow.

• Stripe – Connect Gemini to the Stripe API for payment automation and insights.

Developers can discover and install extensions through the new Gemini CLI Extensions Page, featuring Google, partner, and community-built integrations, ranked by GitHub popularity.

More Than Integration — Built-In Intelligence

Gemini CLI Extensions go beyond simple tool connectivity. They combine Google’s Model Context Protocol (MCP) with AI-driven reasoning, allowing Gemini to intelligently determine the right tool and command for any given task.

Each extension can include:

• MCP servers for connecting to APIs or services

• Context files such as GEMINI.md for tailored instructions

• Custom slash commands for quick execution

• Excluded tools or alternate implementations for deeper control

This design ensures that Gemini can reason across multiple contexts — from codebases and repositories to external systems — with precision and relevance.

Google-Built Extensions for Every Developer

Alongside partner integrations, Google engineers have created a suite of extensions designed to enhance cloud, app, and AI workflows:

For Cloud & DevOps:

• Cloud Run, GKE, gcloud, and Google Cloud Observability extensions streamline deployment, management, and monitoring.

For App Development:

• Code Review and Security extensions bring AI-powered analysis and vulnerability detection to your codebase.

• Flutter, Firebase, Chrome DevTools, and Genkit streamline app building and debugging.

For AI & Data:

• Looker, Data Cloud, and MCP Toolbox for Databases extensions make data exploration and visualization effortless.

• The Nano Banana ?? extension lets developers generate and edit images directly from the CLI — just for fun.

Building the Command Line of the Future

Gemini CLI Extensions are open by design, enabling any developer to build and publish custom integrations. This empowers teams to create toolchains that match their exact needs — from internal workflows to large-scale enterprise systems.

To make building extensions easy, Google has published templates and a step-by-step guide for creating and sharing new extensions with the community.

Availability

Gemini CLI Extensions are available today. Developers can explore available extensions and learn how to build their own at the Gemini CLI Extensions Page.
