Install MCP Superset in mcp-client-cli

What you need first

• mcp-client-cli, installed.
• uv, which gives the uvx command the server starts with.
• Your own values for YOUR_SUPERSET_BASE_URL,YOUR_SUPERSET_USERNAME,YOUR_SUPERSET_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": {
    "mcp-superset": {
      "command": "uvx",
      "args": ["mcp-superset==0.2.3"],
      "env": { "SUPERSET_BASE_URL": "YOUR_SUPERSET_BASE_URL", "SUPERSET_USERNAME": "YOUR_SUPERSET_USERNAME", "SUPERSET_PASSWORD": "YOUR_SUPERSET_PASSWORD" }
    }
  }
}

3. Replace YOUR_SUPERSET_BASE_URL,YOUR_SUPERSET_USERNAME,YOUR_SUPERSET_PASSWORD with your own values.
4. Save the file and restart mcp-client-cli.

Check it worked

Ask mcp-client-cli: List the tools of mcp-superset.

If it does not start

spawn uvx ENOENT

uv is not on the PATH that mcp-client-cli sees. Install it, or write the full path of uvx in the config.

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.
