Gemini CLI extensions

Gemini CLI extensions package prompts, MCP servers, custom commands, hooks, sub-agents, and agent skills into a familiar and user-friendly format. With extensions, you can expand the capabilities of Gemini CLI and share those capabilities with others. They are designed to be easily installable and shareable.

To see examples of extensions, you can browse a gallery of Gemini CLI extensions.

Managing extensions

You can verify your installed extensions and their status using the interactive command:

/extensions list

or in noninteractive mode:

gemini extensions list

Installation

To install a real extension, you can use the extensions install command with a GitHub repository URL in noninteractive mode. For example:

gemini extensions install https://github.com/gemini-cli-extensions/workspace
