Gemini CLI Aetherya aetherya_compare_creatives

How to: Gemini CLI Aetherya aetherya_compare_creatives

client:Gemini CLI transport:streamable-http tool:aetherya_compare_creatives

Add Aetherya to Gemini CLI

  1. 01

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

{
  "mcpServers": {
    "mcp": {
      "httpUrl": "https://mcp.aetherya.ai/mcp"
    }
  }
}
  1. 02

    Save the file and restart Gemini CLI.

  2. 03

    Ask for something aetherya_compare_creatives does. Gemini CLI lists the server's tools on connect and calls aetherya_compare_creatives itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Aetherya's identifier in your config matches the one above exactly.

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

Aetherya will not start until these are set, so aetherya_compare_creatives never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
