GLOBAL FLAGS:
  --port <n>      MCP HTTP port (default: 3100). When omitted, server-bound
                  commands auto-discover the live editor via
                  ~/.openpencil/.op-mcp-port (verified with a JSON-RPC ping)
  --pretty        pretty-print JSON replies
  --file <path>   `op start` document path; otherwise target .op file for
                  tools that accept filePath (omit for the live canvas)
  --page <id>     target page ID for tools that support pageId

The server must be running at:
  http://127.0.0.1:3100/mcp
