McGrath
McGrath is one of Australia's largest residential real estate brokerage networks, founded in Sydney in 1988 by John McGrath and operating a mixed company-owned and franchise network of roughly 118 offices across New South Wales, Queensland, the ACT, Victoria and Tasmania. Its business lines span residential sales, property management and rentals, projects and new-development marketing, rural and livestock, an Asia Desk for offshore buyers, and mortgage broking through Oxygen Home Loans. Listed on the ASX in 2015 as McGrath Limited (ASX:MEA), it was acquired in June 2024 by a consortium of Knight Frank Australia and New Zealand's Bayleys for A$95.5m and delisted from the ASX on 28 June 2024. McGrath sits on the demand side of the Australian property value chain: it is a brokerage that publishes listings into the REA Group (realestate.com.au) and Domain portal duopoly, settles transactions over the PEXA electronic conveyancing network, and consumes valuation data from PropTrack and CoreLogic rather than producing any of those rails itself. Its API posture is honestly nil. No developer portal exists — developer., developers., api., docs., feeds., data. and portal. subdomains of mcgrath.com.au all fail to resolve (NXDOMAIN), and /developers, /api, /docs, /api-docs, /openapi.json, /swagger.json, /$metadata and /.well-known/openid-configuration all return HTTP 404. RESO — the only genuinely mandated machine-readable real estate contract anywhere in this study — is a North American standard driven by NAR and MLS membership; it has no Australian counterpart and McGrath has no RESO Web API or Data Dictionary certification, no OData surface, and no Universal Property Identifier usage. The only interoperability standards McGrath demonstrably implements are robots.txt and twelve XML sitemaps; every /.well-known/ document probed — security.txt, openid-configuration, oauth-authorization-server, api-catalog, ai-plugin.json — and /llms.txt return 404. Its robots.txt enumerates twenty crawler groups including GPTBot, ChatGPT-User, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot and Bytespider, but under RFC 9309 group-matching rules those named AI agents are disallowed only from Google Maps JS/RPC paths — the /properties/ and /search/ disallow lands solely on User-agent: *, so the listing corpus is nominally open to the named AI crawlers and closed to generic ones, while the properties-buy/sold/rent/leased sitemaps advertise those same URLs. Reachability is the harder gate: www.mcgrath.com.au sits behind a Vercel Security Checkpoint that answers scripted clients with HTTP 429 and a browser challenge on every path, so no unattended agent can read the site regardless of robots.txt. The listing inventory is a marketing asset routed to portals under commercial agreements, not a developer surface.

- Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
- MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
- Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
- Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
- Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
- Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
- Contract Quality scores 0.0 — up to +25.0 composite points
- Developer Ergonomics scores 1.2 — up to +19.8 composite points
- Access Clarity scores 10.5 — up to +17.9 composite points
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Consumer Lending Licensing (UK, US, Canada credit licence registers) | undeclared | - | - | - |
| Australia AFS, Credit and ADI Registers (ASIC + APRA licensing) | undeclared | - | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
