Close/disable cluster after amount of use

Hello,
To protect my own work and definition, I always set password to clusters.
I would know if there’s a way to allow a difined quantity of cluster use and then disable it after
the limit is passed

Thx

There isn’t without scripting some hack

And understand that any scripting hack will be easily cracked if it’s important enough.

Thank you both, it is always a fear to be stolen a definition I have worked on for months/year…
