Description
Hey HN. Here's a Mac app I'm working on for making diagrams. It comes with an MCP server so Claude can make and edit diagrams directly. Still in progress, but I'd love some feedback.

Yes A native macOS canvas app paired with a local MCP server that accepts JSON commands to render diagrams is well within the scope of modern AI-assisted Swift development.
