Install YouTrack (ymcp) in TUUI

What you need first

• TUUI, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_YOUTRACK_URL,YOUR_YOUTRACK_LOGIN,YOUR_YOUTRACK_PASSWORD.

Steps

1. Open ~/.codex/config.toml, or create it. The Codex CLI, its IDE extension and the ChatGPT desktop app share this file.
2. Add this table at the end of the file.

{
  "mcpServers": {
    "ymcp": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "YOUTRACK_URL", "-e", "YOUTRACK_LOGIN", "-e", "YOUTRACK_PASSWORD", "docker.io/xlsoftware/ymcp:0.27.0", "serve"],
      "env": { "YOUTRACK_URL": "YOUR_YOUTRACK_URL", "YOUTRACK_LOGIN": "YOUR_YOUTRACK_LOGIN", "YOUTRACK_PASSWORD": "YOUR_YOUTRACK_PASSWORD" }
    }
  }
}

3. Replace YOUR_YOUTRACK_URL,YOUR_YOUTRACK_LOGIN,YOUR_YOUTRACK_PASSWORD with your own values.
4. Save the file and restart TUUI.

Check it worked

Ask TUUI: List the tools of ymcp.

If it does not start

Cannot connect to the Docker daemon

Docker is not running. Start it, then restart TUUI.

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.
