🇬🇷 Greece Invoice MCP live

AI agents can now issue Greece myDATA electronic invoices (τιμολόγιο / timologio). This remote MCP server builds an AadeBookInvoiceType XML and transmits it to the national AADE myDATA platform under your own credentials — two tools: create_invoice, query_invoice.

        "x-aade-subscription-key": "<your Ocp-Apim subscription key>"
      }
    }
  }
}

You register your ERP once on the AADE myDATA portal and receive a user id + subscription key (the developer/test rail issues them instantly). Requests default to the AADE test rail; add x-aade-mode: prod for the live rail. Your credentials stay with you — this server never stores them.

Why it is safe

• Stateless: no database — credentials travel per-request in headers and are never stored.
• Credentials stay with you: we only translate MCP calls to the AADE myDATA REST API under your own user id + subscription key.
• Owner policy guardrails: x-agentpay-max-amount, x-agentpay-approval-above, x-agentpay-allowed-tools — set by the human owner in client config; the agent cannot relax them.

Weak-model friendly

Greek VAT rates enumerated (24 / 13 / 9 / 6 / 4 / 17 / 0) and mapped to AADE vatCategory codes automatically; invoiceType defaults to 1.1 (sales); every result embeds numbered next_steps and the official MARK; every error teaches the fix (VAT number format, VAT rate, exemption code, date format).

Honest limits

There is no cancel at the API level for a submitted invoice — corrections are issued as a credit note (invoice_type 5.1). Income classification (E3) is optional per line — supply income_classification_type / income_classification_category if your accounting requires it.
