Redis MCP server

The Redis MCP server provides a standardized interface for Large Language Models (LLMs) to interact with Redis key-value databases. Through this server, models can perform essential Redis operations like setting values, retrieving data, deleting keys, and listing database contents.

Installation Options

Docker Installation

You can run the Redis MCP server using Docker with the following configuration in your claude_desktop_config.json file:

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

Important notes for Docker:

• When running Docker on macOS, use host.docker.internal if the Redis server is running on the host network
• The Redis URL can be specified as an argument (defaults to "redis://localhost:6379")

NPX Installation

Alternatively, you can run the server using NPX:

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

Available Tools

The Redis MCP server provides four primary operations:

Set Key-Value Pairs

Sets a Redis key-value pair with optional expiration time.

Input parameters:

• key (string): Redis key
• value (string): Value to store
• expireSeconds (number, optional): Expiration time in seconds

Get Values

Retrieves a value from Redis using its key.

Input parameter:

• key (string): Redis key to retrieve

Delete Keys

Deletes one or more keys from the Redis database.

Input parameter:

• key (string | string[]): A single key or array of keys to delete

List Keys

Lists Redis keys that match a specified pattern.

Input parameter:

• pattern (string, optional): Pattern to match keys (defaults to "*")

Usage with Claude Desktop

To use this server with the Claude Desktop application, simply add the configuration shown in the installation section to your claude_desktop_config.json file. Once configured, Claude will be able to interact with your Redis database through these standardized tools.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
