client
Atlantis
A macOS-only client, long-lived and long in beta. Its scripting is documented as no longer working, which is the one honest "no" in this section.
Capabilities
4 of 10 established from the project's own documentation
Read off each project's own documentation, not measured by us — a client has no handshake for us to observe. "unknown" means we looked and did not establish it. It never means no.

Atlantis is a native macOS client that has been around since Mac OS X 10.3 and was updated for 64-bit in the Catalina era. It handles RFC 2066 character-set negotiation and Unicode, which is better than its age would suggest, and it does MCCP and SSL.
The one "no" in this section
Its scripting was Perl, through the CamelBones bridge, and the project's own home page says it no longer works — Apple's handling of Perl changed and the library's author died some years ago. That is a sourced absence, which is a different thing from an unknown, and it is the only cell in the whole client section that carries one. Everywhere else the honest answer was that we could not establish it.
Everything we could not establish
The version history is complete and public and mentions MCCP, SSL and charset negotiation — and never mentions GMCP, MSDP, ATCP or MSP. MXP appears once, as something intended for a version after 1.0.0, which has not arrived.
There is a Perl Atlantis::Speak() call in the scripting API, and it would be easy to read that as
screen-reader support. It is not: it is a scripted text-to-speech call in a scripting system the
project says does not work. VoiceOver, "accessible" and "screen reader" appear on none of the home
page, the downloads page, the full version history, or the archived user guide.
The current download is 0.9.9.8, still nominally a beta, with no release date published anywhere on the site.
