MCP Redis Server

The MCP Redis server lets a Claude-style client run Redis commands through MCP tools. Redis Inc. has published an official implementation under their open-source org that supports strings, hashes, streams, and Redis Stack vector search; several community servers also exist. Typical use: inspect cache keys, prune stale entries, or run a vector similarity search over embeddings stored in Redis.

Frequently asked questions

What is the MCP Redis server good for?

Cache inspection ('what keys match user:1234:*?'), debugging stale entries, and running similarity search when you use Redis Stack as a vector store for RAG.

Does it support Redis Cluster?

Yes, by pointing REDIS_URL at the cluster endpoint. Keep in mind that KEYS and some scan commands fan out across shards and may be slow on large clusters — prefer SCAN with MATCH.

How do I limit destructive commands?

Use Redis ACLs to forbid FLUSHDB, FLUSHALL, CONFIG, and DEBUG for the MCP user, and only expose read-oriented tools in your server build.
