Gemini CLI Multi Mail Prompt/needs_reply

How to: Gemini CLI Multi Mail needs_reply

client:Gemini CLI transport:streamable-http prompt:needs_reply

Add Multi Mail to Gemini CLI

01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "mail": {
      "httpUrl": "https://mail.lumman.co/mcp"
    }
  }
}

02
Save the file and restart Gemini CLI.
03
needs_reply 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 Multi Mail 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 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.
