# facture_facturx

QUAND une facture doit être conforme à la facturation électronique française (réforme e-facture, EN 16931) — le seul outil de ce serveur qui produise un vrai PDF ; tous les autres documents sortent en HTML. Facture Factur-X (PDF/A-3 + XML EN 16931). Attention à la forme du retour : un objet JSON {_mcp_pdf_base64, _mcp_mime}, donc le PDF arrive encodé en base64 DANS du texte — décodez-le avant de l'écrire, ne l'affichez pas tel quel. Rien n'est enregistré ni transmis à l'administration : le dépôt reste votre geste. seller{}, buyer{}, lines[] (description, quantity, unit_price HT, vat_rate). format=preview pour PDF sans XML.
