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.

https://api.fuentio.com/mcp

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.

What you get

• Company lookup and search for France (SIREN, SIRET, name) and Spain (company name, BORME acts since January 2009).
• One record per real company, matched across registers and GLEIF, with the reason for every match and every non-match.
• Company group links (parent and subsidiary companies reported to GLEIF).
• Company history: what changed and when.
• A verify_company check for onboarding (KYB): status, address, identifiers and evidence in one call.
• Insolvency notices (BODACC for France, BORME for Spain).
• Sanctions list screening with clear coverage notes.

• Change alerts with watch_company.

Why agents pick it

• Official sources only, never scraped guesses.
• Every answer includes the source, a link, the check date, an uncertainty label and a receipt id.
• When sources disagree, you see both values, never a silent pick.
• Short answers by default, errors that say exactly what to retry.

Install

Claude Code

claude mcp add --transport http fuentio https://api.fuentio.com/mcp

Claude Desktop / claude.ai: Settings → Connectors → Add custom connector → paste https://api.fuentio.com/mcp.

Cursor / VS Code / any client (JSON), as in this repository's mcp.json:

{ "mcpServers": { "fuentio": { "url": "https://api.fuentio.com/mcp" } } }

VS Code's own .vscode/mcp.json format:

{ "servers": { "fuentio": { "type": "http", "url": "https://api.fuentio.com/mcp" } } }

Gemini CLI: gemini extensions install <this repository's URL> (it reads gemini-extension.json).

Cline: ask Cline to install this server; it follows llms-install.md.

ChatGPT (developer mode): create a connector with the URL above, no authentication.

With a key (paid plans, or a free key for the tools marked "key" below):

{ "mcpServers": { "fuentio": { "url": "https://api.fuentio.com/mcp", "headers": { "Authorization": "Bearer YOUR_KEY" } } } }

A free key (100 units a month, one per person) takes under a minute: curl -X POST https://api.fuentio.com/v1/keys -H "Content-Type: application/json" -d '{"email":"you@example.com"}'. The key arrives by email.
