before you install - you'll need

CML_URL

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add xorrkaz-cml-mcp -- uvx cml-mcp

Claude Desktop / Cursor / VS Code - add to config

  "mcpServers": {
    "xorrkaz-cml-mcp": {
      "command": "uvx",
      "args": [
        "cml-mcp"
      ]
    }
  }
}

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

Using another client? Same JSON, different key
