Greece Invoices (AADE myDATA national API) MCP server

Issue a Greek electronic invoice (τιμολόγιο) into the national AADE myDATA platform. Builds an AadeBookInvoiceType <InvoicesDoc> XML and transmits it to /SendInvoices under your own AADE credentials, returning the official MARK (Μοναδικός Αριθμός Καταχώρησης / unique registration number), invoice UID and QR url. Bring your own credentials as headers: x-aade-user-id (your myDATA user id) and x-aade-subscription-key (your Ocp-Apim subscription key) — both issued by the AADE myDATA portal. Header x-aade-mode: prod switches to the live rail (default = dev / test rail, no fiscal effect). Amounts are in EUR, VAT-exclusive per line. Greek VAT rates map to AADE vatCategory codes automatically: 24 (mainland standard), 13 and 6 (reduced), 17 / 9 / 4 (island reduced), 0 (VAT-exempt, category 7). invoiceType defaults to 1.1 (sales invoice); use 2.1 for a services invoice or 5.1 for a credit note.

Look up one of your own transmitted myDATA documents by its MARK. Calls /RequestTransmittedDocs, which returns your transmitted docs with a MARK greater than the value you pass — so this tool requests from MARK-1 and reports whether the exact MARK you asked for was found (found=true means AADE has it registered). Pass mark=0 to list your transmitted documents from the beginning. Safe to call anytime (read-only).
