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.

How to authenticate

Checked against the endpoint by our probe on 20 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.

Scheme	OAuth

Client ID Metadata Document	✕Not advertised
PKCE	✓S256, plain
Grant types	authorization_code, refresh_token
Scopes	openid, profile, email, phone, offline_access
Protected-resource metadata	✓Published (RFC 9728)
Anonymous access	Handshake succeeds; 5 tools listable
Credentials demanded in prose	✕eini_create_meal_plan 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

1 of the 5 tools listed anonymously say in their own descriptions that they need an account or a key (eini_create_meal_plan), 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.

5 tools usable without signing in

The server exposes a public surface before authorization: eini_search_deals, eini_compare_health_insurance, eini_my_meal_plan, eini_my_shopping_list, eini_create_meal_plan.
