Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Redis MCP Server - 通过 MCP 协议操作 Redis 数据库

Readme

Redis MCP Server

简体中文 | English

让 AI 安全高效地操作 Redis。通过 MCP 协议提供18 个精心设计的工具,在仅消耗 ~1,600 tokens(GPT-4 上下文的 1.2%)的情况下,覆盖 90% 的 Redis 使用场景。

为什么选择这个工具?

| 痛点 | 传统方案 | Redis MCP Server | |------|----------|------------------| | 上下文占用 | 60+ 工具,~5,000+ tokens | 18 工具,~1,600 tokens ✅ | | 生产安全 | KEYS 命令阻塞服务器 | SCAN 实现,永不阻塞 ✅ | | 灵活性 | 新增命令需等待更新 | execute 万能工具,即查即用 ✅ | | 高可用 | 仅支持单机 | Cluster/Sentinel/SSL 全支持 ✅ |

一分钟上手

npm install && npm run build
# .env
REDIS_HOST=localhost
REDIS_PORT=6379
npm start

核心工具(18个)

数据类型操作(12个)

| 类型 | 工具 | 用途 | |------|------|------| | 字符串 | get / set / del | 缓存、Session | | 哈希 | hgetall / hmset | 用户信息、配置存储 | | 列表 | lrange / lpush / lpop | 消息队列、任务队列 | | 集合 | smembers / sadd | 标签、去重 | | 有序集合 | zrange / zadd | 排行榜、延时队列 |

管理与扩展(6个)

| 工具 | 亮点 | |------|------| | keys | SCAN 实现,大数据量不阻塞 | | expire / ttl | 过期时间管理 | | execute | 万能工具,执行任意 Redis 命令 | | batch_execute | Pipeline 批量,性能提升 10x+ | | info / select | 服务管理 |

使用示例

基础操作

// 缓存(带过期时间)
set({ key: "session:123", value: "user_data", ex: 3600 })

// 用户信息存储
hmset({ key: "user:1", fields: { name: "张三", age: "25" } })
hgetall({ key: "user:1" })

// 任务队列
lpush({ key: "queue:tasks", values: ["task1", "task2"] })
lpop({ key: "queue:tasks" })

// 排行榜
zadd({ key: "rank:daily", members: [{ member: "user1", score: 100 }] })
zrange({ key: "rank:daily", start: 0, stop: 9, withscores: true })

万能工具 - execute

当 18 个工具不够用时,使用 execute 执行任意命令:

// 原子递增
execute({ command: "hincrby", args: ["user:1", "views", 1] })

// 按分数范围查询
execute({ command: "zrangebyscore", args: ["rank", 100, 200] })

// 事务操作
execute({ command: "multi" })
execute({ command: "incr", args: ["counter"] })
execute({ command: "exec" })

批量操作(Pipeline)

// 一次往返执行多个命令,性能提升 10x+
batch_execute({
  commands: [
    { command: "get", args: ["key1"] },
    { command: "hgetall", args: ["hash1"] },
    { command: "zrange", args: ["rank", 0, 9] }
  ]
})

安全地查找键

// 使用 SCAN 实现,大数据量不会阻塞服务器
keys({ pattern: "user:*" })

生产环境配置

只读模式(安全)

REDIS_READONLY=true

禁止写入操作,只允许查询,适合生产数据分析。

Cluster 集群

REDIS_CLUSTER=true
REDIS_CLUSTER_NODES=node1:6379,node2:6379,node3:6379

Sentinel 高可用

REDIS_SENTINEL=true
REDIS_SENTINEL_MASTER_NAME=mymaster
REDIS_SENTINEL_NODES=s1:26379,s2:26379,s3:26379

SSL/TLS 加密

REDIS_TLS_CA=/path/to/ca.pem
REDIS_TLS_CERT=/path/to/client-cert.pem
REDIS_TLS_KEY=/path/to/client-key.pem

在 Claude 中使用

VS Code 配置

.vscode/settings.json 中添加:

{
  "mcpServers": {
    "redis": {
      "command": "npx",
      "args": ["-y", "@wenit/redis-mcp-server"],
      "env": {
        "REDIS_HOST": "localhost",
        "REDIS_PORT": "6379",
        "REDIS_PASSWORD": "",
        "REDIS_DB": "0"
      }
    }
  }
}

本地开发配置

{
  "mcpServers": {
    "redis": {
      "command": "node",
      "args": ["/path/to/redis-mcp-server/dist/index.js"],
      "env": {
        "REDIS_HOST": "localhost",
        "REDIS_PORT": "6379",
        "REDIS_PASSWORD": ""
      }
    }
  }
}

故障排查

// 测试连接
ping({})

// 查看服务器信息
info({ section: "server" })

// 查看内存使用
info({ section: "memory" })

// 查看慢查询
execute({ command: "slowlog", args: ["get", 10] })
