Gemini CLI spreadsheet builder Prompt/explore_sheet

How to: Gemini CLI spreadsheet builder explore_sheet

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

Add spreadsheet builder to Gemini CLI

  1. 01

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

{
  "mcpServers": {
    "spreadsheet-builder": {
      "httpUrl": "https://mcp.zovo.one/mcp/spreadsheet-builder"
    }
  }
}
  1. 02

    Save the file and restart Gemini CLI.

  2. 03

    explore_sheet 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.

  3. 04

    If it does not appear, check that spreadsheet builder 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

Set these first

spreadsheet builder will not start until these are set, so it never reaches Gemini CLI.

Same prompt, other clients

Read from the server itself, by connecting to it and calling prompts/list on 24 September 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.
