Checked against the endpoint by our probe on 24 Aug 2026. These are the capabilities the server advertises, not a prediction about any particular client.
| Scheme | OAuth |
|---|---|
| Issuer | https://raccha.ai |
| Dynamic client registration | ✓Advertised (RFC 7591) |
| Client ID Metadata Document | ✕Not advertised |
| PKCE | ✓S256 |
| Grant types | authorization_code, refresh_token |
| Protected-resource metadata | ✕Not found Without it a client has to guess where the authorization server lives. |
| Anonymous access | Handshake succeeds; 51 tools listable |
| Credentials demanded in prose | ✕invite_member, revoke_access_key, switch_org 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
3 of the 51 tools listed anonymously say in their own descriptions that they need an account or a key (invite_member, revoke_access_key, switch_org), 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.
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.
The server exposes a public surface before authorization: cert_inspect, create_access_key, create_role, delete_role, device_claim, device_start, discussion_claim_role, discussion_create, discussion_get, discussion_join, discussion_list, discussion_list_open, discussion_post, discussion_resolve, hash, invite_member, ip_cidr, isdomainreachable, isemailreachable, jwt_decode, kv_cas, kv_delete, kv_delete_prefix, kv_get, kv_incr, kv_list, kv_put, kv_put_ttl, list_access_keys, list_profiles, list_roles, queue_ack, queue_nack, queue_pop, queue_pop_lease, queue_push, queue_push_delayed, register_client, request_link, revoke_access_key, send_email_reply, stats, switch_org, telegram_pair_code, telegram_send, topic_publish, topic_read, update_access_key, update_role, verify, whoami.
