What is the best MCP servers and plugin for software architecture?

By tashan's measured score: Cocoindex Code, Codedna, Haytham, Archy, Excalidraw Skill. the score combines upkeep and freshness, gated by real adoption — every input is public and linked to its source.

How is the ranking calculated?

From public signal only: npm download volume and publish cadence, GitHub push/release recency, contributor count, registry status, and how often a capability appears in real public agent configs. Nobody can pay to change a score, rank, or listing.
