Fuentio: France & Spain company data from official registries

Official company checks for France and Spain, for AI agents.

Fuentio is a remote MCP server (and REST API) that looks up, searches and verifies companies in France and Spain from official registries: INSEE Sirene and the national company register for France, BORME (Registro Mercantil acts since 2009) for Spain, and GLEIF for LEIs and company group links. Every answer cites its source and check date. No setup, free tier.

Ask your agent "Is this supplier still active?", "Which company is behind this SIREN?" or "¿Sigue activa esta sociedad según el BORME?" and get an answer you can trust and prove.
