# Greece Invoice MCP

> A remote MCP server that lets any AI agent issue Greece myDATA electronic invoices (τιμολόγιο / timologio) into the national AADE (ΑΑΔΕ) platform. It builds an AadeBookInvoiceType <InvoicesDoc> XML in the invoice namespace, transmits it under the merchant's own AADE credentials, and returns the official MARK (unique registration number), invoice UID and QR url. Stateless, bring-your-own credentials, never stores anything.

- MCP endpoint (Streamable HTTP): https://inv-gr.wishpool.app/mcp
- Credentials headers: x-aade-user-id (your myDATA user id, forwarded as aade-user-id), x-aade-subscription-key (your Ocp-Apim subscription key from the AADE myDATA portal, forwarded as ocp-apim-subscription-key), x-aade-mode: prod for the live rail (default = dev / test rail, no fiscal effect). Credentials stay with the merchant and travel per-request in headers.
- Flow: create_invoice -> MARK + invoice UID + QR url; query_invoice(mark) confirms AADE has the document registered (RequestTransmittedDocs).
- Amounts in EUR, VAT-exclusive per line. Greek VAT rates map to AADE vatCategory automatically: 24 standard (cat 1), 13 (cat 2), 6 (cat 3), 17 (cat 4), 9 (cat 5), 4 (cat 6), 0 exempt (cat 7, needs a vatExemptionCategory 1-31). invoiceType defaults to 1.1 (sales); 2.1 services; 5.1 credit note.
- No cancel at the API level: corrections are credit notes (invoiceType 5.1). Honest.

## Tools

- create_invoice: Build an AadeBookInvoiceType invoice from counterpart VAT + lines (net_value, vat_rate) and transmit it to AADE myDATA /SendInvoices. Returns the official MARK, invoice UID, QR url and computed VAT totals.
- query_invoice: Look up one of your own transmitted myDATA documents by its MARK via /RequestTransmittedDocs; found=true means AADE has it registered. Pass mark=0 to list from the start.
- Owner policy guardrails: x-agentpay-max-amount (hard cap on invoice gross total in EUR), x-agentpay-approval-above (returns an unsigned draft for human review), x-agentpay-allowed-tools (tool allow-list) — set by the human owner in the MCP client config; the agent cannot relax them.

## Safety

Stateless translation layer over the national AADE myDATA REST API. The merchant's user id + subscription key travel per-request in headers; this server never stores credentials, invoices, or customer data. Privacy policy: https://inv-gr.wishpool.app/privacy
