Uruguay DGI e-Factura (CFE): AI agents submit signed sobres to DGI e-invoicing, stateless forwarder.
Scored across 6 tools
Each tool has a distinct purpose: building unsigned envelopes, tax calculation, reference info, querying status, and submitting two different document types (sobre and reporte diario). No overlapping functionality.
All tool names follow a clear verb_noun pattern with underscores (build_cfe_envelope, calc_iva, get_dgi_info, query_envio_status, submit_reporte_diario, submit_sobre). Consistent and descriptive.
Six tools is well-scoped for a DGI SOAP relay server: it covers envelope building, tax calculation, reference info, querying, and two submission types. Not excessive nor insufficient.
Core workflow (build envelope, calculate taxes, submit, query) is covered. Lacks a tool for parsing DGI responses or for signing (intentionally external), but these are minor gaps given the server's relay focus.
