01 · Install YAML Workflow

Claude Code

claude mcp add orieg-yaml-workflow -- uvx yaml-workflow

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "orieg-yaml-workflow": {
      "command": "uvx",
      "args": [
        "yaml-workflow"
      ]
    }
  }
}

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

Using another client? Same JSON, different key
