It does not reliably know that MCP Apps moved from meta[\"openai/outputTemplate\"] to meta.ui.resourceUri , or that A2UI reached v1.0 candidate in June 2026. On fast-moving specs, every model's training is stale in a way it cannot detect — it answers confidently with last year's field names. That is what this server is for: dated, cited, extracted primary-source content that beats both a smaller model's guess and a frontier model's expensive live re-research. Features Core Capabilities - 🎯 Vector + Keyword Search - Supabase pgvector with pluggable embeddings (Cloudflare Workers AI bge-m3 , edge-native and free within the Workers plan; OpenAI optional), plus a Postgres full-text path that keeps working when embeddings are unavailable - 📚 395 Curated Entries - W3C standards, WCAG 2.2, ARIA practices, major design systems, and agent-interface protocols - 🚦 Relevance Floor - IDF-weighted scoring means an uncovered topic returns nothing rather than confident, adjacent content - 🚀 Edge-Optimized - C","default_branch":null,"files":null,"tree":[],"storefront":"/r/southleft","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/southleft/design-systems-mcp/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
