NPM tool as agent requirement in build configuration

We have some required tools as part of our build chain that are supposed to be installed via NPM on the agent machine (namely, netlify for uploading builds to a test environment), I'm wondering what's the best way to define this dependency, and if there's any way to make an agent fetch that tool (basically run a npm install) if it doesn't have it yet in order to run a build, similar as what happens with Tools you can create manually and upload to TC.

Thanks!
