How to: Gemini CLI Lumière PayCheck check_before_paying
Add Lumière PayCheck to Gemini CLI
-
01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.

"paycheck": {
"httpUrl": "https://lumierepaycheck.org/mcp?plans=1"
}
}
}-
02
Save the file and restart Gemini CLI.

check_before_paying is surfaced in the client's prompt or command menu. Unlike a tool, you invoke it deliberately — Gemini CLI will not call it for you.

04
If it does not appear, check that Lumière PayCheck is connected and that you are looking at its prompts 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 prompt, other clients
Read from the server itself, by connecting to it and calling prompts/list on 7 October 2026.
A listing does not declare its prompts, 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 prompt's arguments.
