Gemini CLI extension that adds Gemini API docs and MCP

Gemini API docs extension for Gemini CLI

This extension provides documentation support for building with the Gemini API on the Gemini CLI or other MCP-enabled tools.

Gemini CLI installation

You can clone the repository directly into the Gemini CLI extensions directory. Choose between a global installation (available to your user everywhere) or a local installation (for the current workspace).

Global Installation

mkdir -p ~/.gemini/extensions
git clone https://github.com/markmcd/gemini-docs-ext.git ~/.gemini/extensions/gemini-docs-ext

Workspace Installation

mkdir -p ./.gemini/extensions
git clone https://github.com/markmcd/gemini-docs-ext.git ./.gemini/extensions/gemini-docs-ext

Gemini CLI will automatically load the extension on startup.

Other tools

You can adapt this extension to provide context for other tools or APIs by following these steps:

1. Create a system .md file: Copy the contents of GEMINI.md to your tool's system instructions, e.g. CLAUDE.md or CONTEXT.md.

2. Add the MCP servers: gemini-extension.json contains a fairly standard MCP configuration. You may be able to copy the mcpServers block directly into your tool's MCP configuration.
