Registers this connector fills
Australian Business Register keeps 1 register current in Civil Memory. Each name is the record you ask for, not the system it came from - ask for it in Studio or from your own AI client.
| Register | What it holds | Fields from Australian Business Register |
|---|---|---|
Platform entity attrplatform_entity_attr | ABR registration details for a contractor ABN. | Fills all of 13 |
The full field list, requiredness and an example record for any register are on its published contract. Where more than one system fills a register, the register is the same shape either way.
Integration model
Section titled “Integration model”ABR is a lookup API: the adapter sends an ABN, ACN or name and returns the register’s entity record. Demiton maintains the API registration centrally, so there is no per-tenant authentication step.
Connection setup
Section titled “Connection setup”The ABR connector is platform-managed - no credentials required on your side. Demiton maintains the API registration centrally. Browse and pin ABR datasets from the Open Data Catalog (/hq-platform/catalog for platform administrators, or query the curated set from any account).
Example queries via MCP
Section titled “Example queries via MCP”Once connected through the MCP server, you can ask Claude:
- “Is [Supplier Name] GST-registered? What’s their entity type?”
- “Look up ABN 12 345 678 901 - what is this entity?”
- “Which of our vendors have cancelled ABNs?”
- “Verify the ACN for [company] against the register.”
Security
Section titled “Security”Access type: Read-only (public data)
The ABR exposes publicly available business registry data. All data retrieved is publicly accessible - no private or sensitive information is involved. No credentials are required or stored on your account.
