Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
Chess data via chess.ceo — 11.7M+ games and 1.5M FIDE player profiles. 8 tools: player search, per-player opening preparation (opening tree with frequency + win rate), position statistics from the full game database, head-to-head records, and live tournament broadcasts. No API key. Remote server at https://mcp.chess.ceo/mcp or local via npx -y @chessceo/mcp.
WHOOP recovery, sleep, strain, and workouts with server-side analysis: trends, lag-aware correlations, training load, and full-history export. Demo mode needs no WHOOP account; one-command setup for Claude, Cursor, and VS Code.
