v0.1.0 — first release

First release of sketch/design: a hand-drawn whiteboard for system design mock interviews, with an MCP server that turns Claude or ChatGPT into your interviewer.

Install

Claude Desktop (one-click): download sysdesign-board-0.1.0.mcpb below and double-click it.

Other apps: the package isn't on npm yet. Clone the repo, run npm install && npm run build, and point your MCP client at node /path/to/sysdesign-board/server/dist/index.js. See the README for Claude Code, Codex CLI, ChatGPT and other clients.

Requires Node.js 18+.

What's in it

The board

• Pencil-style canvas with paper and chalkboard themes
• 27 system design components
• Arrows that stay attached to components, with labels, curved or elbow routes, and dashed lines for async flows
• Pen, text, sticky notes, zones and a laser pointer, plus undo/redo, keyboard shortcuts and PNG/JSON export

The interview

• A panel with the problem, timer, phase tracker and chat
• Voice input and spoken replies, using the browser's built-in speech

The interviewer's tools (13)

• Read the board as structured data, or look at it as an image
• Wait for you to speak or finish drawing, and talk back
• Pin comments on components, highlight them, and draw reference designs
• End with a feedback card of 1–5 scores

Running it

• Commands: serve, install (Claude Desktop on macOS, Windows and Linux) and token
• Security: the board only answers on localhost, and the HTTP /mcp endpoint for ChatGPT connectors needs a token

Everything runs on your machine, and the AI uses your existing Claude or ChatGPT subscription, with no API keys.
