Catalyst integrates with the Modrinth API from the server detail page. The content browser chooses the right content type for the server platform.

4

Install

Catalyst chooses a compatible version, downloads required dependencies, verifies hashes when available, and writes the files to plugins/ or mods/.

​
Installed content

Catalyst tracks installed Modrinth projects in .catalyst/modrinth.json inside the server folder. The installed list can update or remove tracked projects.
Manual files placed in plugins/ or mods/ still work at the server level, but Catalyst only knows how to update or remove projects recorded in its Modrinth manifest.

​
Dependency handling

Catalyst resolves required Modrinth dependencies recursively. Optional dependencies are not forced. Downloads are written with safe filenames and kept inside the content directory.
Restart the server after installing, updating, or removing most plugins and mods. Hot-loading depends on the server software and the plugin or mod itself.
