Australia Company Register MCP

Connect your AI assistant to about 3.9 million Australian private and public companies from the Australian Business Register through The Company Atlas and the Model Context Protocol.

Search:

  • Companies by registered name, as a substring or a prefix
  • ABN (Australian Business Number) and ACN (Australian Company Number) lookups
  • Company type (private or public), ABN status (active or cancelled, about 1.8 million cancelled), state or territory, and postcode
  • Trading, business and former names recorded against the ABN, and the date the ABN status last changed

Street addresses, incorporation dates, directors and shareholders are not included.

The MCP connection is provided by The Company Atlas. This repository does not run a separate server.
