Lets LLM clients such as Claude, ChatGPT and Cursor search, fetch, issue and track Moldova SFS electronic invoices, check async post status, assign serials, and look up taxpayers in the registry. Each user authenticates with their own e-Factura credentials via OAuth 2.1 + PKCE, so invoices can be managed in natural language without touching SOAP or XML.
