Install veto in Gemini CLI

What you need first

  • Gemini CLI, installed.
  • Docker, which gives the docker command the server starts with.
  • Your own value for YOUR_CONFIG.

Steps

  1. Open ~/.gemini/settings.json, or create it. For one project only, use .gemini/settings.json in that project.
  2. Add this block. If the file already has mcpServers, add only the entry inside it.
{
  "mcpServers": {
    "veto": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "ghcr.io/aiveto/veto:0.1.13", "serve", "--config", "YOUR_CONFIG"]
    }
  }
}
  1. Replace YOUR_CONFIG with your own value.
  2. Save the file and restart Gemini CLI.

Check it worked

Ask Gemini CLI: List the tools of veto.

If it does not start

Cannot connect to the Docker daemon
Docker is not running. Start it, then restart Gemini CLI.
The server starts, but its tools fail
A YOUR_… placeholder is still in the config, or its value is wrong.
Nothing changes after a restart
The file is not valid JSON any more. Look for a missing comma where the block was added.
