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 18 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.
| Scheme | No auth |
|---|---|
| Protected-resource metadata | ✕Not found Without it a client has to guess where the authorization server lives. |
| Anonymous access | Handshake succeeds; 58 tools listable |
| Credentials demanded in prose | ✕generate_image, generate_video, animate_image, analyze_image, generate_text, generate_music, text_to_speech, transcribe_audio, transcribe_translate, translate_epub, generate_3d_model, extract_document, convert_file, send_email, clone_voice, edit_image, merge_pdfs, convert_html_to_pdf, render_card, translate_text, translate_rare_language, extract_receipt, e_signature, epub_to_audiobook, send_sms, place_call, send_fax, ai_call, open_voice_bridge, remove_background, upscale_image, restore_face, estimate_depth, detect_nsfw, detect_objects, remove_object, colorize_image, deblur_image 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
38 of the 58 tools listed anonymously say in their own descriptions that they need an account or a key (generate_image, generate_video, animate_image, analyze_image, generate_text, generate_music, text_to_speech, transcribe_audio, transcribe_translate, translate_epub, generate_3d_model, extract_document, convert_file, send_email, clone_voice, edit_image, merge_pdfs, convert_html_to_pdf, render_card, translate_text, translate_rare_language, extract_receipt, e_signature, epub_to_audiobook, send_sms, place_call, send_fax, ai_call, open_voice_bridge, remove_background, upscale_image, restore_face, estimate_depth, detect_nsfw, detect_objects, remove_object, colorize_image, deblur_image), 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.
