Impossible_Bit_2676 · reddit · 2026-10-14

A free, MIT-licensed MCP service for Australian business identity checks separates deterministic validateabn (checksum) from verifyabn (live Australian Business Register lookup returning status, entity details, and GST registration), plus validateacn — so agents don't mistake a passing checksum for a verified, active business. Deployed as a remote Streamable HTTP MCP and listed in the official MCP Registry.
