SaglitzDesign
An expert design & marketing brain for your AI coding agent.
SaglitzDesign is an open-source MCP server. It gives Claude, Cursor and any MCP client prescriptive, sourced guidance on web, iOS, Android and macOS design, plus the UX, copywriting, SEO, GEO and marketing knowledge that makes a product convert. Runtime-independent, offline, no account.
Why
LLMs are confidently wrong about design: defaults, outdated specs, generic "make it clean and modern" advice. SaglitzDesign swaps that for a curated, sourced, prescriptive knowledge base your agent queries on demand, like a senior product designer, a conversion copywriter and a technical SEO at once.
Install
Node 18+. One line for Claude Code; a config snippet for Claude Desktop or Cursor.
