Website SDK — @4hum-ai/jawb-sdk

For website owners, not for automating jawb itself (see the Rust SDK for that). Lives in the separate jawb-sdk repo.

Currently ships one helper:

import { declareWebMcpTools } from "@4hum-ai/jawb-sdk";

const tag = declareWebMcpTools([
  { name: "book_service", description: "Book a service appointment" },
]);
// -> <script type="application/webmcp+json">{"tools":[...]}</script>

Inject the returned string into your page's <head>. The helper escapes script-unsafe characters, so a description containing </script> cannot end the tag early. Agents read your tool names and descriptions, so keep them accurate, and never put instructions aimed at the agent in them. jawb-core's tools crate discovers and parses this tag — see WebMCP.

The real scope of this SDK (merchant/commerce integration) is a later deliverable; this helper is the only piece implemented so far.
