-
01

}
}
}-
02
Save the file and restart Gemini CLI.

find_a_client 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 Rex Software MCP by usefulapi 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 11 November 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.
