Built a local design canvas for agents to draw on via MCP, enabling Figma-like capabilities
_IruaDev · reddit · 2026-08-21
The author built a local Mac app with a localhost MCP server, allowing AI agents to draw directly on a local design canvas. It supports layers, editable text, auto layout, and undo, storing files as local JSON with export options for PNG/JPG/SVG. The local deployment avoids metered tool call costs. This bridges the gap where Figma AI cannot access local repos or assets. The author also discusses the granularity of agent tools: whether to use a few large tools (create a card) or many small ones (createrectangle).
