How we ranked Memory & Knowledge MCP servers
Ranked by the stored quality_score, then non-monorepo repository stars; shared monorepo stars are excluded from the star tie-break. Remaining ties use server slug order. Up to ten visible published or generated entries are shown. Missing scores sort below recorded scores. We do not reconstruct or invent a score.
Stars and last push prefer the latest GitHub stats row, with server fields as fallback. Shared repositories are explicitly labeled repo stars (monorepo), never per-server stars. Tools are documented snapshots, not live capability checks.
Re-ranked from request-time data. Indexing requires six editorially published servers, including three pushed within six months, plus explicit publication approval.
