OpenPencil

CLI and MCP server for .fig design files. Two modes of operation:

• App mode — connect to the running OpenPencil editor (omit the file argument)
• Headless mode — work with .fig files directly (pass a file path)

# App mode — operates on the document open in the editor
bun open-pencil tree

# Headless mode — operates on a .fig file
bun open-pencil tree design.fig

The app exposes an automation bridge on http://127.0.0.1:7600 when running. The CLI auto-connects to it when no file path is provided.
