Why GPL-2.0-only, and why the "only" is load-bearing
--------------------------------------------------------------------------------

This project imports piqtree, which declares GPL-2.0-only — without the "or any
later version" clause. A work combining GPL-2.0-only code cannot be relicensed
forward to GPL-3.0, so this project is GPL-2.0-only too. That is a consequence of
the dependency, not a preference: the sibling servers in this family are MIT and
GPL-3.0-or-later respectively, each set by what they link against.

Citation
--------------------------------------------------------------------------------

IQ-TREE 2 is academic software and expects to be cited when used in published
work. This server drives it; it does not replace that obligation. If results from
this tool appear in a publication, cite IQ-TREE 2 — and the substitution-model
selection or bootstrap method actually used — as directed at
http://www.iqtree.org/, not this wrapper.

Author and institution details are deliberately not restated here. They belong to
the upstream project, which publishes its own current citation; a hand-copied
byline is exactly the kind of thing that goes stale or attributes the wrong
people.

--------------------------------------------------------------------------------
Affiliation
--------------------------------------------------------------------------------

This project is an independent, UNOFFICIAL Model Context Protocol server. It is
not affiliated with, endorsed by, or sponsored by the IQ-TREE authors or the
cogent3 project. Package and project names are used only to identify the software
this server drives.
