    <!-- Domain Coverage -->
    <h2>Domains Covered</h2>
    <p>26 domains with full coverage, 3 partial. Each would otherwise need a separate MCP server (npm process).</p>

    <h2>How to Use</h2>
    <p>Assay is a Lua scripting runtime, not an MCP server. Your AI agent writes scripts using Assay's stdlib modules. Use <code>assay context "&lt;query&gt;"</code> for LLM-ready docs.</p>
