Overview

What is Code Summarizer?

A command-line and MCP server tool that recursively summarizes code files in a given directory using Google Gemini Flash 2.0. It integrates with LLM tools like Claude Desktop, Cursor AI, and Cline, and is designed for developers who want to quickly understand codebases without manual reading.

How to use Code Summarizer?

Install Node.js 18+, clone the repository, install dependencies, configure a GOOGLE_API_KEY environment variable, then use the CLI with npm start -- summarize [directory] or start the MCP server with npm start -- server. The server port (default 24312) can be changed via npm start -- config set --port 8080. Connect LLM tools by setting up a JSON config file or using SSE transport with an API key header.
