How to authenticate
Checked against the endpoint by our probe on 8 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.
| Scheme | OAuth |
|---|---|
| Issuer | https://sgpropertydata.com |
| Dynamic client registration | ✕Not advertised A client that cannot register itself needs credentials issued out of band before it can begin the flow. |
| Client ID Metadata Document | ✕Not advertised |
| PKCE | ✕None advertised MCP requires S256; a client that implements only that has no method in common with this server. |
| Protected-resource metadata | ✓Published (RFC 9728) |
| Anonymous access | Handshake succeeds; no tools listable |
What the probe found
A cross-origin preflight came back without Access-Control-Allow-Origin, so the endpoint is reachable from native clients only — code running in a web page is stopped by the browser before a request is ever sent.
