What the code does

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

    const child = spawn(process.execPath, [playwrightCli(), 'install', 'chromium'], {

        const buf = await fs.readFile(path.join(outputDir, rel));

This one needs environment variables set before it will start: ALLCHEMY_API_KEY (Beta API key from https://beta.allchemylabs.ai (optional: without it the scanner runs fully offline with template fixes)). The author declared them in the registry entry; get the values from the project itself.
