Gemini API Docs MCP Extension for Gemini CLI

This is a Gemini CLI extension that integrates the Gemini API Documentation MCP, providing your AI agent with real-time access to the official Gemini API documentation, including best practices, code examples, and model capabilities.

The purpose of this extension is to facilitate installation of the Gemini API Documentation MCP server into Gemini CLI using the standard extension installation mechanism.

One-Line Installation

To install this extension into your Gemini CLI, run:

gemini extensions install https://github.com/derailed-dash/gemini-api-docs-mcp-ext

Once installed, simply start the Gemini CLI and run /mcp to verify the gemini-api-docs-mcp.dev tools are loaded.

What This Extension Does

By providing the agent with a direct line to the official documentation, this extension enables the Gemini CLI to:

• Retrieve the latest information on Gemini models (Flash, Pro, etc.)
• Understand Gemini API features like Context Caching, Function Calling, and Structured Outputs
• Get up-to-date SDK usage examples for Python, Node.js, Go, and more
• Stay informed about the latest documentation updates and coding standards

This makes the extension incredibly useful for developers building applications with Gemini, ensuring the AI agent providing help has the most accurate and current context available.

How It Works

This extension is a lightweight wrapper that configures the Gemini CLI to use the gemini-api-docs-mcp.dev server. It uses the Model Context Protocol (MCP) to allow Gemini to "search" and "read" official documentation as needed.
