Opinionated changes and enhancements to the default minibuffer completion UI of Emacs:

• Live completions to update the results as you type.

• Passlist and blocklist of commands or completion categories to control whether the *Completions* buffer shows up eagerly.

• Other relevant options to control when the *Completions* are displayed.

• Per command or completion category sorting methods.

• A cleaner *Completions* buffer, optionally without a mode line.

• Commands to cycle from the minibuffer to the *Completions* and vice versa.

In essence, MCT is (i) a layer of interactivity on top of the out-of-the-box completion experience, and (ii) glue code that combines built-in functionalities to make the default completion framework work like that of more featureful third-party options.
