概覽

AI 產生的概覽

遠端 MCP 伺服器，可將公司解析為官方登記紀錄，並執行營業稅、制裁、IBAN 與錢包位址合規查核。

可以做什麼
  • 依名稱、網域或登記號碼將公司解析為官方登記紀錄，支援單筆與最多 25 筆批次
  • 驗證歐盟營業稅號（VIES），並依 OFAC、歐盟、聯合國與英國制裁名單篩選名稱
  • 一次呼叫完成供應商 KYB 查核，綜合登記資料、營業稅與制裁結果並給出結論
  • 驗證 IBAN 與收款人國家是否相符，並篩選加密錢包位址是否列於 OFAC 名單
適用情境
適合供應商上架、發票交易對象核驗、跨境 B2B 銷售反向課稅判斷，以及付款前核對銀行帳戶與錢包位址等情境。
執行需求
需要一個遠端 streamable HTTP 端點；免費額度不需註冊或 API 金鑰。每日 5 次免費呼叫之外需付費，可透過 x402（Base 上的 USDC）或信用卡購買預付額度，並以付款中繼資料或 API 金鑰方式提交。
安裝前請注意
超出每日免費額度後按次計費（每次 0.002 至 0.025 美元），可能要求提供付款憑證或錢包資金。公司、個人、營業稅號、IBAN 與錢包位址等查詢內容會傳送給第三方服務。結果雖為唯讀，但不能取代正式的合規意見。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Agentum Entity Resolver，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.Algiras%2Fagentum-entity-resolver/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

README

Agentum — Global Corporate Entity, VAT & Sanctions Resolver for AI Agents

Registry availability depends on the server configuration. UK Companies House is verified locally; hosted UK access is not yet confirmed. Australian ABR and New Zealand NZBN are disabled without credentials; Japan NTA is pending approval. GLEIF lookup can still return LEI holders in these countries. Check /v1/coverage for the connected server’s current registry coverage.

Zero-Signup Streamable HTTP MCP Server & REST API for deterministic corporate entity resolution across global national registries (UK Companies House, Swiss ZEFIX, Singapore ACRA, US SEC EDGAR, European Registries, and Worldwide GLEIF LEI), live EU Commission VIES VAT validation, and OFAC SDN + EU Financial Sanctions + UN Security Council screening (26,650+ live records).
