HopGraph MCP Server

Verify Australian and New Zealand businesses against government registers via any MCP-compatible AI agent.

Returns registration status, directors, licences, trading names, and a three-tier risk assessment (CLEAR / ADVISORY / FLAGS_FOUND) that surfaces regulatory findings across jurisdictions — including bans, disqualifications, insolvencies, and disqualified directors that may not appear in any single register.

Each verification produces an immutable compliance record with a unique audit UID.

Compatible with Claude, ChatGPT, Cursor, and any MCP-compatible AI client.

Tools

verify_business

Verify any Australian or New Zealand business against government registers. Accepts ABN (11 digits), ACN (9 digits), NZBN (13 digits), or company name.

Returns registration status, directors, licences, trading names, and a three-tier risk assessment (CLEAR / ADVISORY / FLAGS_FOUND). For Australian entities, cross-references adviser registrations against banned persons registers across entity licence chains. For New Zealand entities, checks every director against the NZ Companies Office Disqualified Directors and Insolvency registers in real time, and screens them against Australian regulatory registers.

Each verification produces an immutable compliance record with a unique audit UID. Findings are labelled as "Exact name match" or "Partial name match" so you can apply the appropriate level of scrutiny.

| Parameter | Required | Description |
|-----------|----------|-------------|
| identifier | Yes | ABN, ACN, NZBN, or company name to verify |
| country | No | AU or NZ. Auto-detected from identifier format if omitted |

search_business

Search Australian and New Zealand business entities by name. Covers 2.3 million+ Australian companies, 3.2 million business names, and New Zealand NZBN-registered entities.

Use this to find the correct identifier before calling verify_business.

| Parameter | Required | Description |
|-----------|----------|-------------|
| query | Yes | Business name or partial name to search for |
| limit | No | Maximum results to return (default 20, max 50) |

expand_person_network

Discover all NZ company directorships and shareholdings held by a named person via the NZ Companies Office register. Returns every company where the person holds a role — company name, NZBN, status, role type, and appointment date — plus flags for companies already in the HopGraph database.

Use this to map a person's corporate network beyond what a single entity lookup reveals.

| Parameter | Required | Description |
|-----------|----------|-------------|
| person_name | Yes | Full name of the person to search for (e.g. "Stephen Mikkelsen") |
| role_type | No | Filter by role type: DIR (directors), SHR (shareholders), or ALL (default) |

get_verification

Retrieve a previously generated compliance verification record by its unique audit UID. Returns the immutable entity snapshot captured at verification time, data sources consulted with freshness timestamps, and the risk assessment result.

| Parameter | Required | Description |
|-----------|----------|-------------|
| verification_uid | Yes | The verification UID (UUID) returned by a previous verify_business call |

get_verification_history ^{Professional+}

Retrieve the verification history for a specific entity, showing all past compliance checks you have run against it. Returns verification dates, risk assessment results, and audit UIDs. Useful for tracking how an entity's compliance status has changed over time.

Requires a Professional or Business tier API key — upgrade at hopgraph.com/billing.

| Parameter | Required | Description |
|-----------|----------|-------------|
| identifier | Yes | ABN, ACN, NZBN, or company name used in previous verify_business calls |
