Install codeDB Lens in TUUI

What you need first

• TUUI, installed.
• Docker, which gives the docker command the server starts with.
• Your own values for YOUR_ENGINE,YOUR_SERVER.

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": {
    "codedb-lens": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "ghcr.io/codedb-io/codedb-lens:0.9.1", "mcp", "--engine", "YOUR_ENGINE", "--server", "YOUR_SERVER"]
    }
  }
}

3. Replace YOUR_ENGINE,YOUR_SERVER with your own values.
4. Save the file and restart TUUI.

Check it worked

Ask TUUI: List the tools of codedb-lens.

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.
