Fuentio: France & Spain company data

Fuentio：專為AI代理打造的法國與西班牙官方公司資料。 問「這家供應商還在營業嗎？」、「這個SIREN背後是哪家公司？」或「¿Sigue activa esta sociedad según el BORME?」，即可獲得可信且可驗證的答案。 您將獲得：法國（SIREN、SIRET、名稱）與西班牙（公司名稱、自2009年1月以來的BORME公告）的公司查詢與搜尋。 每家真實公司對應一筆記錄，跨註冊機構與GLEIF比對，並附上每次比對的理由。 公司集團連結（向GLEIF申報的母公司與子公司）。 公司歷史：變更內容與時間。 用於入職審查（KYB）的verify_company檢查：狀態、地址、識別碼與證據一次取得，並附證明碼。 法國破產公告（BODACC，自2008年以來）。 代理選擇它的原因：僅使用官方來源，絕無爬蟲猜測。 每個答案都包含來源、連結與查詢日期。 當來源不一致時，您會看到兩個值，絕不默默選一個。 錯誤訊息會明確指出重試方式。 限制說明：僅限法國與西班牙。 無西班牙NIF/CIF查詢、無完整財務報表、無個人資料。 定價：免金鑰免費層（每日20單位）或免費金鑰（每月100單位），詳見fuentio.com。 付費方案每月49歐元起，詳見fuentio.com/pricing。

文件

Official company records your agent can use, and cite.

Fuentio runs an MCP server, so Claude, Cursor and any MCP client can verify a French or Spanish company in the middle of a task. Every answer starts with one plain sentence and ends with its source.

Built for AI agents: one MCP server and one REST API, with honest gaps: what isn't covered is said, never guessed.

Every country, covered or not →

Connect it to your agent

  1. Claude Code One command, no key needed to start. 
    claude mcp add --transport http fuentio https://api.fuentio.com/mcp
    With a key 
    claude mcp add --transport http fuentio https://api.fuentio.com/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"
  2. Claude Desktop and claude.ai
    1. Settings → Connectors → Add custom connector. 2. Name: Fuentio. URL: the address below. Then Add. 3. In a chat, turn on Fuentio from the tools menu and ask, for example, “Is SIREN 441639465 still active?” Custom connectors can't send a key, so they use the keyless trial.

  3. Cursor In ~/.cursor/mcp.json, or.cursor/mcp.json in a project. 
    {
  "mcpServers": {
    "fuentio": {
      "url": "https://api.fuentio.com/mcp"
    }
  }
}

      }
    }
  }
}
  4. VS Code (GitHub Copilot agent mode) In.vscode/mcp.json. With a key, VS Code asks for it once and stores it securely.

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

  5. ChatGPT (developer mode)
    1. Settings → Apps & Connectors → Advanced settings: turn on Developer mode. 2. Create a connector: name Fuentio, MCP server URL: the address below, authentication: No authentication. 3. In a chat, pick the connector from the tools menu and ask your question. Menu names change often; ChatGPT's help pages have the current path. ChatGPT connectors use the keyless trial.

The tools Live

  • list_coverage () Free Which countries and identifier formats are covered, and how fresh the data is. Call it first when unsure.
  • lookup_company (country, identifier, id_scheme?, format?) 1 unit Verify a company before onboarding, paying or contacting it. France: SIREN, SIRET or VAT number. Spain: Registro Mercantil sheet.
  • search_companies (country, query, postal_code?, locality?, status?, page?, format?) 2 units Find a company by name when you don't know its number.
  • get_company_history (country, identifier, page?) 1 unit See what changed at a company (status, address, name, legal form) and when, with the official source of each change. Spain also gets its BORME acts as dated events.
  • verify_company (country, identifier, id_scheme?, reference?) 5 units A KYB check for onboarding, or before paying or signing: an outcome (verified, partial or unverified), the reasons and a proof code. Use lookup_company for a quick read, and search_companies first when you only have a name.
  • resolve_company (country, name?, identifier?, postal_code?, locality?) 2 units Is this the same company? Match a supplier or customer record (an official ID, or a name with a postcode or town) to the official registers: candidates, each with a decision and the reasons. Only an official ID links; a name is never proof.
  • explain_match (left, right) 1 unit Why two register records are, or are not, the same company: the decision, the reason codes and the evidence.
  • watch_company (entity_id, callback_url) 1 unit Watch a company: when its official records change, Fuentio sends the changes, signed, to your https endpoint. Needs an API key.

lookup_company and search_companies, and the REST lookup and search, take an optional format. Same units, except a search file with more than 25 rows: 2 units per started 25 rows.

What your agent sees

A real record from our snapshot, as the lookup tool returns it:

The tool call

lookup_company({"country": "FR", "identifier": "441639465"})

The first line your agent reads

RENAULT (FR, SIREN 441639465) is active as of 2025-12-06, source: Annuaire des Entreprises (API Recherche d'entreprises).

Then the full record as JSON, with its source, licence and check time.

Prefer plain REST?

The same data over HTTPS. Try it without a key, then create a free key in one call.

A free trial without a key (20 units a day), and free keys with 100 units a month.
