Asked
“Find Spanish companies named Telefónica in the BORME.”
Tool
search_companies{"country": "ES", "query": "telefonica"}Answer, as returned
10 of 251 companies matching 'telefonica' in ES (page 1), source: BORME — Boletín Oficial del Registro Mercantil (Sección A).

Use resolve_company for that." } }Why this matters Spanish companies can't be looked up by NIF, so search ranks names with a score and its reasons, and never decides for you.

Asked
“Look up Spanish NIF B12345678.”
Tool
lookup_company{"country": "ES", "identifier": "B12345678"}Answer, as returned
invalid_identifier: 'B12345678' has the format of a NIF/CIF but its check digits are wrong. Next step: Spanish tax-ID (NIF/CIF) lookup isn't supported. Search by company name instead: search_companies(country='ES', query='<company name>').
Why this matters A polite decline with the next step, not a made-up company.

“Who are the directors of Renault?”
Tool No tool returns people
Answer, as returned
There is no tool for that. The server states it in its own tool descriptions:

{ "tools": 17, "lookup_company": "Limits: 1 unit (also a valid ID not found); keyless 20/day. France: insolvency from BODACC since 2008. Spain: BORME acts since 2 January 2009. No person's name in any answer." }Why this matters Fuentio checks companies only: no person's name in any answer.
Recorded on 12 October 2026 from https://api.fuentio.com/mcp.
Why Fuentio
- France and Spain in one schema, through one REST API and one MCP server.
- Every fact carries its source, its link and its check date; a verification gives a proof code.
- When sources disagree you see both values, never a silent pick.
- Honest gaps: every answer says what could not be confirmed.
- Built for AI agents: works in Claude as a custom connector and in other MCP clients, and is listed on Smithery.
