Will my client connect?

Decided from what the probe found at the endpoint, and from what each client's own documentation says it can complete. Every row carries the day that documentation was read.

✓Claude CodeConnects with setup

Neither RFC 7591 registration nor a Client ID Metadata Document is advertised, so register a client with the issuer yourself and give Claude Code the client ID.

✕ChatGPTNot supported

Registering a client by hand is not a flow ChatGPT documents, and this server advertises none that it does.

How to authenticate

Checked against the endpoint by our probe on 29 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.

Scheme	OAuth
Issuer	https://clerk.quantwright.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	✓S256
Grant types	authorization_code, refresh_token, urn:ietf:params:oauth:grant-type:device_code
Scopes	openid, profile, email, public_metadata, private_metadata, offline_access
Protected-resource metadata	✓Published (RFC 9728)
Anonymous access	Handshake succeeds; 6 tools listable

What the probe found

No CORS headers for browser-based clients

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.

6 tools usable without signing in

The server exposes a public surface before authorization: describe_data, create_study, run_backtest, get_result, run_held_out_test, compare_trades.

No server card

Neither the reserved <endpoint>/server-card location nor the domain's /.well-known/ai-catalog.json describes this endpoint (SEP-2127), so a client that discovers servers by domain will not find it.
