Chess.com MCP — wraps the Chess.com public API (free, no auth)

This Redis MCP server, created by fahrankaz, provides a bridge between Model Context Protocol clients and Redis databases. It supports core Redis operations like GET, SET, SADD, SMEMBERS, ZADD, ZRANGE, ZRANGEBYSCORE, ZREM, HGET, HGETALL, HMSET, DEL, and SCAN. The implementation is designed as a lightweight CLI tool that starts a Node.js server, making it easy to integrate with existing MCP setups. It's particularly useful for scenarios requiring fast, in-memory data storage and retrieval within AI workflows, such as caching intermediate results or maintaining session state across multiple AI interactions.
