Custom TCA validations in TYPO3

How do I create a custom validation for a TCA field? We want to check the input of a textfield with an AJAX-request. So it should be done with JS. If I check the FormEngineValidation.js it seems there is no option for using custom validators.

Is that right? Or did I miss something?

The 'eval' api of FormEngine is still rather ugly.

ext:styleguide brings an example for input_21 that adds some JS magic using returnFieldJS(), this may or may not be enough for your use case.
