Reuse Before Generate MCP Server

When you ask an AI coding assistant to build an app or module, it overenthusiastically starts scaffolding thousands of lines of code from scratch - even when battle-tested open-source libraries or maintained tools already exist. It runs locally over stdio via the published package.

People who work with code reuse and developer tools and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

01 · Install Reuse Before Generate

before you install - you'll need

GITHUB_TOKEN

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add aradar46-reuse-before-generate -- npx -y reuse-before-generate

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "aradar46-reuse-before-generate": {
      "command": "npx",
      "args": [
        "-y",
        "reuse-before-generate"
      ]
    }
  }
}

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

Using another client? Same JSON, different key
