Redis MCP server for checking keys, TTLs, and basic cache health in Redis.

What it can do

• get-key — read a key, show its type, TTL, size, and a decoded preview.
• set-key — write a key with JSON or string data, plus an optional TTL, when you explicitly opt in to writes.
• inspect-server-info — read Redis INFO and break it into easy-to-scan fields.

Setup

You only need 1 env var:

• REDIS_URL — your Redis connection string. If you use Redis Cloud, open your database's Connect flow and copy the client connection details: https://redis.io/docs/latest/operate/rc/databases/connect/ . If you run Redis locally, redis://localhost:6379 usually works.

Cursor config

}

Quick example

"Check why session:user:42 keeps vanishing from Redis. Use get-key to inspect it, then run inspect-server-info and look for eviction or memory clues before you suggest any write."
