01 · Install Workflows MCP Server

before you install - you'll need

Set MCP_TRANSPORT_TYPE, WORKFLOWS_DIR before connecting.

Claude Code

claude mcp add cyanheads-workflows-mcp-server -- npx -y @cyanheads/workflows-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "cyanheads-workflows-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "@cyanheads/workflows-mcp-server"
      ]
    }
  }
}

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

Using another client? Same JSON, different key
