Core Tools

Core tools have installation logic built into mise. They do not require a separately installed plugin. Their language guides explain platform support, compilation options, virtual environments, and other runtime-specific behavior.

List the current core entries with:

mise registry -b core

Selecting another implementation

Installing an external plugin with the same name can override a core tool. Use that only when you need behavior provided by the plugin; it also changes the installation and trust requirements. See plugins and backend selection for how mise chooses an implementation.

To select the built-in implementation explicitly, use the core: prefix, for example mise use core:python@3.14. The registry covers tools beyond the core set.
