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

1. 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 server is not running or unreachable
• Solution:
  • Verify Redis is running: redis-cli ping should return "PONG"
  • Check Redis service status: systemctl status redis (Linux) or brew services list (macOS)
  • Ensure correct port (default 6379) is not blocked by firewall
  • Verify Redis URL format: redis://hostname:port

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

Components

Tools

• set

  • Set a Redis key-value pair with optional expiration
  • Input:
    • key (string): Redis key
    • value (string): Value to store
    • expireSeconds (number, optional): Expiration time in seconds

• get

  • Get value by key from Redis
  • Input: key (string): Redis key to retrieve

• delete

  • Delete one or more keys from Redis
  • Input: key (string | string[]): Key or array of keys to delete

• list

  • List Redis keys matching a pattern
  • Input: pattern (string, optional): Pattern to match keys (default: *)

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"

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

NPX

{
  "mcpServers": {
    "redis": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-redis",
        "redis://localhost:6379"
      ]
