For a QR pointing to https://google.com just pass data: 'https://google.com'.\n  \u2022 Barcode 'ecLevel' (L|M|Q|H) applies ONLY to format='qr' and is ignored elsewhere. Use 'H' for printed media.\n  \u2022 EAN-13 'data' must be exactly 12 or 13 digits (the 13th check digit is auto-computed if you pass 12).\n  \u2022 sign_pdf accepts ONLY DER-encoded inputs in base64. Convert from PEM with: openssl pkey -in key.pem -outform DER | base64 -w0  (and openssl x509 -in cert.pem -outform DER | base64 -w0 for the cert).\n  \u2022 sign_pdf RSA key must be PKCS#1 DER (field 'rsaKeyPkcs1DerBase64'). ECDSA key may be SEC1 or PKCS#8 DER (field 'ecPrivateKeyDerBase64') or the raw 32-byte scalar as 64 hex chars (field 'ecPrivateScalarHex').\n  \u2022 sign_pdf auto-injects a placeholder when missing \u2014 call it directly on ANY PDF unless you specifically need to customize the placeholder.\n  \u2022 For Factur-X / ZUGFeRD invoices, use add_attachment (PDF/A-3) \u2014 generate_basic_pdf cannot embed files.\n  \u2022 PDF/A: pass pdfA='pdfa2b' for the widest reader compatibility. PDF/A-3 is required when you have attachments.\n  \u2022 outputMode='file' is only available when the host sets PDFNATIVE_MCP_OUTPUT_DIR; otherwise PDFs are returned as base64.\n\nEvery tool ships JSON-Schema-typed inputs/outputs, _meta.apiVersion = '1.0.0', and worked-example _meta.examples.
