DevLens

Overview

DevLens is a Model Context Protocol server that lets you query a precomputed code graph of TypeScript, JavaScript, React, Next.js, and Node.js repositories. It exposes nodes, edges, and summaries as tools that AI assistants can invoke, giving models deep insight into your codebase structure and relationships.

The server runs locally via the npm package @devlensio/cli, which communicates over stdio with your MCP client. No authentication is required — install and use it immediately. Version v0.5.5 is available under the AGPL-3.0 license, with source code at devlensio/devlensOSS on GitHub, where the project has earned 55 stars.

DevLens belongs in the Development category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain DevLens, claim this listing to verify ownership and keep the information current.
