YAML Workflow

YAML Workflow runs locally from a Python package published to PyPI: yaml-workflow version 0.9.6. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Python; clients usually start it with uvx (from uv) or after pip install — the usual command is uvx yaml-workflow. Required arguments: --dir.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

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