Overview

AI-generated overview

Lets an assistant search about 3.9 million Australian companies by name, ABN, ACN, status, state and postcode, and look up trading names.

What it does
Provides two tools over a remote MCP endpoint. Australia_search_companies searches registered company names by substring or prefix and filters by entity type (private or public), ABN status (active or cancelled), state or territory, and exact postcode, with pagination up to 50 results per page. Australia_get_company retrieves one company by 11-digit ABN or 9-digit ACN and adds trading, business and former names plus the date the ABN status last changed. Results include an id built from the ABN and an id2 holding the ACN.
When to use it
Useful when an assistant needs to verify or research Australian business entities: checking whether a company is active or cancelled, finding companies by name or location, resolving an ABN or ACN, or listing trading names recorded against a number. It is a lookup service, not a source of full corporate records.
Requirements
A remote Streamable HTTP endpoint at the provider's MCP URL, added as a custom connector in an MCP-compatible client. Sign-in with Google OAuth is required when prompted. No local runtime, package, environment variable or header is declared.
Before you install
Access is tied to a Google sign-in, so the provider sees the account used. Queries are sent to a third-party service. The data covers registered names, ABN status, entity type, state, postcode and trading names only; street addresses, incorporation dates, directors and shareholders are not included, so it should not be relied on for ownership or due-diligence conclusions.
