Dev Lens MCP Server

Intelligent codebase visualizer. Turn any TypeScript, JavaScript, Python, Go, Rust, or Java repository into a living, queryable graph - every node carries a functional summary, a technical summary, and a security assessment. It runs locally over stdio via the published package.

People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

  "mcpServers": {
    "devlensio-devlensoss": {
      "command": "npx",
      "args": [
        "-y",
        "@devlensio/cli"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
