The first fiscal MCP server for Spain. Autónomos and gestorías lose hours mapping IAE ↔ CNAE 2025 codes and guessing which AEAT forms (036/130/303/347…) apply — and general AI agents confidently hallucinate tax facts. This server gives any MCP client a direct line to the real data: 1,187 IAE codes (AEAT), 1,060 CNAE 2025 codes (INE), the IAE↔CNAE crosswalk, IRPF/IVA módulos, AEAT obligations and the 2026 RETA brackets — answering from official sources instead of guessing. 6 of the 10 tools are free (no key, no signup); 4 premium tools (obligations, módulos, bulk lookup, RETA quota) target gestorías and fintech, from €29/mo. Spain-only, by design. Every tool carries the `readOnlyHint` annotation.
