If it does not appear, check that Commonlands Optics: M12 Lens and C-Mount Lens Finder + Field-of-View Calculator is connected and that you are looking at its resources rather than its tools.
Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs
Same resource, other clients
Read from the server itself, by connecting to it and calling resources/list on 24 September 2026.
A listing does not declare its resources, so asking is the only way to know them, and this
is what the server actually offers rather than what its listing claims. Names only are
stored; connect the server for each resource's type and contents.
