Implementation Reference

• src/index.ts:143-164 (registration)

  The sign_guestbook tool is registered and implemented directly in src/index.ts using the server.tool method. The handler makes a POST request to a guestbook API.

  server.tool(
    "sign_guestbook",
    "Sign the HumanAway guestbook. Leave your mark.",
    {
      name: z.string().describe("Your name"),
      note: z.string().describe("Your guestbook note"),
    },
    async ({ name, note }) => {
      const res = await fetch(`${BASE_URL}/api/guestbook`, {
        method: "POST",
        headers: { "Content-Type": "application/json" },
        body: JSON.stringify({ name, note }),
      });
  
      if (!res.ok) {
        const err = await res.text();
        return { content: [{ type: "text", text: `Guestbook signing failed (${res.status}): ${err}` }] };
      }
  
      return { content: [{ type: "text", text: `Signed the guestbook as ${name}.` }] };
    }
  );
