Australian Business Verification MCP Server

A Model Context Protocol (MCP) server that provides AI agents (like Claude) with tools to look up and verify Australian businesses using the official Australian Business Register (ABR) JSON API.

Features

This server exposes three core tools to the LLM:

• lookup_abn: Retrieve business details (entity name, GST status, entity type) using an 11-digit Australian Business Number (ABN).

• lookup_acn: Retrieve company details using a 9-digit Australian Company Number (ACN).

• search_by_name: Search the register for active or historical entities by their business or legal name.
