Code Lens

Overview

Code Lens is a Model Context Protocol server that brings Gemini-powered code analysis directly into your AI assistant. It handles code explanation, refactoring suggestions, code review, and more by integrating as callable tools rather than requiring manual back-and-forth between applications.

The server runs locally on your machine through the npm package @j0hanz/code-lens-mcp, communicating via stdio with no authentication required. Version v0.12.0 is the latest release, with full source code available at j0hanz/code-lens on GitHub.

Code Lens belongs in the Development category on mcp.site and works with any MCP-compatible client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed.
