Redis MCP server

This Redis MCP Server is a management and control protocol implementation for Redis operations built with Spring Boot and Spring AI. It provides a convenient way to interact with your Redis server through SSE-based MCP functionality, making Redis operations more accessible and manageable.

Installation

Prerequisites

• JDK 17 or higher
• Maven 3.6 or higher
• Redis server

Building from Source

mvn clean package

Running the Server

Start the server using the generated JAR file:

java -jar target/redis-mcp-server-{version}.jar

By default, the server connects to Redis at redis://localhost:6379. You can specify a different Redis server using the redis.url system property:

java -Dredis.url=redis://your-redis-host:6379 -jar target/redis-mcp-server-{version}.jar

Usage

Configuring in Cursor

To use this MCP server in Cursor, add the following configuration to your Cursor settings:

{
  "redis-mcp-server": {
    "url": "http://localhost:8080/sse",
    "enabled": true
  }
}

Available MCP Tools

The server provides the following Redis management tools:

Set a Key-Value Pair

Use the set tool to create or update Redis key-value pairs with optional expiration time.

Get a Value

Use the get tool to retrieve a value from Redis by its key.

Delete Keys

Use the delete tool to remove one or multiple keys from Redis.

List Keys

Use the list tool to find Redis keys matching a specific pattern.

API Endpoints

The server exposes MCP functionality through Server-Sent Events (SSE) at:

http://localhost:8080/sse

This endpoint handles all Redis operations through the MCP protocol.

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.
