Interact with Redis key-value stores

Redis

A Model Context Protocol server that provides access to Redis databases. This server enables LLMs to interact with Redis key-value stores through a set of standardized tools.

Prerequisites

Redis server must be installed and running
- Download Redis
- For Windows users: Use Windows Subsystem for Linux (WSL) or Memurai (Redis-compatible Windows server)
- Default port: 6379

Common Issues & Solutions

Connection Errors

ECONNREFUSED

Cause: Redis/Memurai server is not running or unreachable
Solution:
- Verify server is running:
  - Redis:
```
redis-cli ping
```
    should return "PONG"
  - Memurai (Windows):
```
memurai-cli ping
```
    should return "PONG"
- Check service status:
  - Linux:
```
systemctl status redis
```
  - macOS:
```
brew services list
```
  - Windows: Check Memurai in Services (services.msc)
- Ensure correct port (default 6379) is not blocked by firewall
- Verify Redis URL format:
```
redis://hostname:port
```
- If
```
redis://localhost:6379
```
  fails with ECONNREFUSED, try using the explicit IP:
```
redis://127.0.0.1:6379
```

Server Behavior

The server implements exponential backoff with a maximum of 5 retries
Initial retry delay: 1 second, maximum delay: 30 seconds
Server will exit after max retries to prevent infinite reconnection loops

Usage with Claude Desktop

To use this server with the Claude Desktop app, add the following configuration to the "mcpServers" section of your

claude_desktop_config.json

Docker

when running docker on macos, use host.docker.internal if the server is running on the host network (eg localhost)
Redis URL can be specified as an argument, defaults to "redis://localhost:6379" (use "redis://127.0.0.1:6379" if localhost fails)

{
  "mcpServers": {
    "redis": {
      "command": "docker",
      "args": [
        "run", 
        "-i", 
        "--rm", 
        "mcp/redis", 
        "redis://host.docker.internal:6379"]
    }
  }
}
