Gemini CLI Submitator Prompt/client_progress_update

How to: Gemini CLI Submitator client_progress_update

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

Add Submitator to Gemini CLI

  1. 01

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

{
  "mcpServers": {
    "mcp": {
      "httpUrl": "https://mcp.submitator.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Gemini CLI.

  2. 03

    client_progress_update 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 Submitator 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

Submitator 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 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.
