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.

✕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 8 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.

Scheme	OAuth
Issuer	https://accounts.google.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	✓plain, S256
Grant types	authorization_code, refresh_token, urn:ietf:params:oauth:grant-type:device_code, urn:ietf:params:oauth:grant-type:jwt-bearer
Protected-resource metadata	✓Published (RFC 9728)
Anonymous access	Handshake succeeds; 15 tools listable
Credentials demanded in prose	✕execute_sql, execute_sql_readonly, create_user, update_user, import_data These tools are listed anonymously and their own descriptions ask for an account or key, but no challenge is issued — so a client has nothing to act on and the refusal arrives as a tool error.

What the probe found

warningTools needing credentials are listed without a challenge

5 of the 15 tools listed anonymously say in their own descriptions that they need an account or a key (execute_sql, execute_sql_readonly, create_user, update_user, import_data), but the endpoint issued no WWW-Authenticate challenge. The requirement is stated only in prose, so a call reaches the tool and comes back as a tool error instead of an authorization step.

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.

15 tools usable without signing in

The server exposes a public surface before authorization: list_instances, get_instance, create_instance, execute_sql, execute_sql_readonly, get_operation, create_user, update_user, clone_instance, update_instance, list_users, create_backup, restore_backup, import_data, postgres_upgrade_precheck.
