Install Phantom Secrets in Gemini CLI

~/.gemini/settings.json · windows: %USERPROFILE%\.gemini\settings.json 

{
  "mcpServers": {
    "phantom-secrets-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "phantom-secrets-mcp"
      ]
    }
  }
}

Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs
