How to authenticate

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	No auth
Protected-resource metadata	✓Published (RFC 9728)
Anonymous access	Handshake succeeds; 7 tools listable
Credentials demanded in prose	✕convert_file 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.
Documentation	https://changethisfile.com/docs/authentication

What the probe found

warningTools needing credentials are listed without a challenge

1 of the 7 tools listed anonymously say in their own descriptions that they need an account or a key (convert_file), 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.
