01 · Install Codeix

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add montanetech-codeix -- npx -y codeix

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "montanetech-codeix": {
      "command": "npx",
      "args": [
        "-y",
        "codeix"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
