Implementation Reference
- src/index.ts:1203-1237 (handler)Handler function that executes the tool logic: lists ACM certificates using ListCertificatesCommand, describes each to check expiration date with DescribeCertificateCommand, filters those expiring within 'days' threshold (default 30), and returns a JSON list.if (name === "list_expiring_certificates") { const days = (args as any)?.days || 30; const thresholdDate = new Date(Date.now() + days * 24 * 60 * 60 * 1000); const listCmd = new ListCertificatesCommand({}); const listResp = await acmClient.send(listCmd); // Note: paginates 1000 by default const expiringCerts = []; // We need to describe to get 'NotAfter' for (const certSummary of listResp.CertificateSummaryList || []) { if (!certSummary.CertificateArn) continue; try { const descCmd = new DescribeCertificateCommand({ CertificateArn: certSummary.CertificateArn }); const descResp = await acmClient.send(descCmd); const cert = descResp.Certificate; if (cert && cert.NotAfter && cert.NotAfter < thresholdDate) { expiringCerts.push({ DomainName: cert.DomainName, CertificateArn: cert.CertificateArn, NotAfter: cert.NotAfter, Status: cert.Status, InUseBy: cert.InUseBy }); } } catch (err) { // Ignore } } return { content: [{ type: "text", text: JSON.stringify(expiringCerts, null, 2) }] }; }
