Code Assistant

Overview

Code Assistant is an MCP server that brings Gemini-powered code analysis into your AI workflows. It examines code for explanations, refactoring opportunities, and quality improvements, then exposes these capabilities as tools your AI assistant can invoke directly.

The server runs locally on your machine via the npm package @j0hanz/code-assistant, communicating over stdio with zero setup friction. No authentication is required. Version v2.0.0 is available now, with the source code maintained at j0hanz/code-assistant on GitHub.

Code Assistant is listed in the Development category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim your listing here to earn the Verified badge and keep the information up to date.
