The first fiscal MCP server for Spain: IAE/CNAE 2025, AEAT modelos, IRPF/IVA, RETA quota.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 14 October 2026. No other catalogue keeps this.
Today is the operative word: we check Conversor IAE-CNAE every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 13 min ago.
