Install Last.fm in TUUI

What you need first

• TUUI, installed.
• Docker, which gives the docker command the server starts with.
• Your own value for YOUR_LASTFM_API_KEY.

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": {
    "lastfm-mcp": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "LASTFM_API_KEY", "ghcr.io/ndyakov/lastfm-mcp:0.2.0"],
      "env": { "LASTFM_API_KEY": "YOUR_LASTFM_API_KEY" }
    }
  }
}

3. Replace YOUR_LASTFM_API_KEY with your own value.
4. Save the file and restart TUUI.

Check it worked

Ask TUUI: List the tools of lastfm-mcp.

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.
