概覽

AI 產生的概覽

遠端 MCP 伺服器，用來驗證澳洲 ABN 與 ACN 的格式與檢查碼，並即時向澳洲商業登記處查核 ABN。

可以做什麼
  • 驗證 ABN 的格式與檢查碼，回傳正規化、格式化及整體驗證結果
  • 向澳洲商業登記處查核 ABN，回傳登記比對狀態、實體名稱與類型、ABN 狀態、GST 登記狀態、州與郵遞區號、商號及登記更新資訊
  • 驗證 ACN 的格式與檢查碼，回傳正規化與格式化結果
適用情境
適合助理在表單填寫、客戶建檔、開立發票或盡職調查類問題中核對澳洲商業號與公司號，並區分僅檢查碼有效與確實能在登記處查到的 ABN。
執行需求
需要遠端 streamable HTTP 端點；公開測試版工具目前不需 API 金鑰。未宣告本機執行環境、帳號或環境變數。
安裝前請注意
此服務會記錄工具名稱、成功狀態與登記查詢結果等營運使用中繼資料，但不會刻意在應用程式使用日誌中儲存 ABN 與 ACN 輸入值。檢查碼有效不等於已註冊或處於有效狀態，應以登記處查核結果為準。此端點被描述為公開測試版，可能有所變動。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 AU Business Identity，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.creatorhub121%2Fau-business-identity/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

AU Business Identity

Australian business identifier validation and live ABN registry verification for AI agents and applications.

Part of AU Agent Utilities.

What it does

AU Business Identity provides three MCP tools for working with Australian business identifiers:

  • Validate ABNs using official format and checksum rules
  • Verify ABNs live against the Australian Business Register
  • Validate ACNs using official format and checksum rules

Use validate_abn when you only need deterministic local validation.

Use verify_abn when you need to know whether an ABN can be found in the Australian Business Register and retrieve available registry information.

MCP tools

validate_abn

Validates the format and checksum of an Australian Business Number without performing a registry lookup.

Example:

text
51 824 753 556

Returns structured information including:

  • Normalised ABN
  • Formatted ABN
  • Format validity
  • Checksum validity
  • Overall validation result

verify_abn

Verifies an Australian Business Number against the Australian Business Register.

Example:

text
51 824 753 556

Returns structured information that may include:

  • Normalised and formatted ABN
  • Checksum validity
  • Registry match status
  • Entity name
  • Entity type
  • ABN status
  • GST registration status
  • State and postcode
  • Business names when available
  • Registry update information

A checksum-valid ABN and a registry-verified ABN are not treated as the same thing.

validate_acn

Validates the format and checksum of an Australian Company Number.

Example:

text
004 085 616

Returns structured information including:

  • Normalised ACN
  • Formatted ACN
  • Format validity
  • Checksum validity
  • Overall validation result

Example agent requests

text
Is 51 824 753 556 a valid ABN?
text
Verify ABN 51 824 753 556 against the Australian Business Register.
text
Is this ABN active and registered for GST?
text
Validate ACN 004 085 616.

MCP endpoint

No API key is currently required for the public beta tools.

Quick MCP examples

Validate an ABN:

json
{  "name": "validate_abn",  "arguments": {    "abn": "51 824 753 556"  }}

Verify an ABN against the Australian Business Register:

json
{  "name": "verify_abn",  "arguments": {    "abn": "51 824 753 556"  }}

Validate an ACN:

json
{  "name": "validate_acn",  "arguments": {    "acn": "004 085 616"  }}

HTTP endpoints

Checksum validation is also available over HTTP:

text
/validate-abn?abn=51824753556
text
/validate-acn?acn=004085616

Live ABR verification is currently exposed through the MCP tool verify_abn.

Planned capabilities

Potential future additions include:

  • Business-name search
  • ABN and business-name matching
  • Expanded Australian entity verification
  • Additional business identity checks based on real usage demand

Privacy

The service records operational usage metadata such as tool name, success status and registry outcome to help measure reliability and adoption.

ABN and ACN input values are not intentionally stored in application usage logs.

Development

Install dependencies:

bash
npm install

Run tests:

bash
npx vitest run
