          const content = await fs.readFile(usagePath, 'utf-8');

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.

<!-- Custom JavaScript Select (requires basecoat.min.js + select.min.js, or all.min.js) -->

    const entries = await fs.readdir(path.join(__dirname, baseDir), { withFileTypes: true });
