It’s buried in my dotfiles and not easily extracted. But the idea isn’t a hard one to implement, except the coding engineers are woefully unaware of themselves. Codex is easier because it’s open source. Claude you kind of have to futz with it for a while. Once you have the intermediate form working and outputting config for the two I’m sure you can coerce it to any other agent that comes along with similar constructs (marketplaces, etc). Theres some nuance for some MCPs particular those that download binaries like rust MCPs but its very complex I found and probably better to avoid unless you really need it.
