Implementation Reference

• src/modules/web.ts:43-52 (handler)

  The implementation of the 'web_ssl_check' tool handler using fetch to check HTTPS status and security headers.

  server.tool("web_ssl_check", "Check SSL certificate details for a domain", {
    domain: z.string().describe("Domain name (e.g. github.com)")
  }, async ({ domain }) => {
    try {
      const res = await fetch(`https://${domain}`, { method: "HEAD" });
      return { content: [{ type: "text", text: `**SSL Check:** ${domain}\nHTTPS: ${res.ok ? "VALID" : "ERROR"}\nStatus: ${res.status}\nHeaders: ${[...res.headers.entries()].filter(([k]) => k.includes("strict") || k.includes("security")).map(([k, v]) => `${k}: ${v}`).join("\n") || "No security headers"}` }] };
    } catch (e: any) {
      return { content: [{ type: "text", text: `**SSL Check:** ${domain}\nError: ${e.message}` }] };
    }
  });
