Sketch - Collaborative SVG Canvas

Description

Opens a Fabric.js-based SVG editor in the browser for collaborative visual prototyping. Codex can write and read SVG through MCP tools while the user edits interactively. Changes sync in real-time via WebSocket.

Preflight

If the editor shows "disconnected" or WebSocket errors occur, stale server processes may be blocking. Run this before retrying:

pkill -f 'sketch-mcp-server/dist/index.js'

Then reconnect the MCP server (the next tool call will restart it). The server now auto-kills stale instances on startup, but orphaned processes from before this fix may still linger.
