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

Scheme	OAuth
Issuer	https://volunteerreminder.com
Dynamic client registration	✓Advertised (RFC 7591)
Client ID Metadata Document	✕Not advertised
PKCE	✓S256
Grant types	authorization_code, refresh_token
Scopes	read, schedules:write, contacts:write, reminders:write
Protected-resource metadata	✓Published (RFC 9728)
Anonymous access	Handshake succeeds; 23 tools listable
Credentials demanded in prose	✕list_schedules, list_contacts, add_contacts, assign_contacts_to_schedule, import_volunteer_schedule, get_open_days, get_reminder_settings, set_reminder_rule, remove_reminder_rule, send_test_reminder, get_pricing, start_checkout 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.
