Claude Code

claude mcp add thebarmaeffect-glassbox -- npx -y @glassbox-framework/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "thebarmaeffect-glassbox": {
      "command": "npx",
      "args": [
        "-y",
        "@glassbox-framework/mcp"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

npm package @glassbox-framework/mcp - the @glassbox-framework scope differs from the repo owner (thebarmaeffect); confirm it's the project's official package
