Overview

Description from the maker (original English)

Inspect and operate Next.js Redis caches: health, tag state, SWR simulation, safe invalidation.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Clinics & health
  • You need to fill in: REDIS_URL

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: REDIS_URL, DEPLOYMENT_VERSION, HASH_TAG

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "nextjs-cache-handler": {
      "command": "npx",
      "args": [
        "-y",
        "@leejpsd/nextjs-cache-handler-mcp"
      ],
      "env": {
        "REDIS_URL": "your-value",
        "DEPLOYMENT_VERSION": "your-value",
        "HASH_TAG": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add nextjs-cache-handler --env REDIS_URL=your-value --env DEPLOYMENT_VERSION=your-value --env HASH_TAG=your-value -- npx -y @leejpsd/nextjs-cache-handler-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "nextjs-cache-handler": {
      "command": "npx",
      "args": [
        "-y",
        "@leejpsd/nextjs-cache-handler-mcp"
      ],
      "env": {
        "REDIS_URL": "your-value",
        "DEPLOYMENT_VERSION": "your-value",
        "HASH_TAG": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "nextjs-cache-handler": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@leejpsd/nextjs-cache-handler-mcp"
      ],
      "env": {
        "REDIS_URL": "your-value",
        "DEPLOYMENT_VERSION": "your-value",
        "HASH_TAG": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • REDIS_URL secret required env
    Redis connection string the cache handler uses
  • DEPLOYMENT_VERSION env
    Deploy namespace (recommended)
  • HASH_TAG env
    Set 'true' when handlers use hashTag: true (Redis Cluster)

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Nextjs Cache Handler MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: REDIS_URL

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@leejpsd/nextjs-cache-handler-mcp

MCP (Model Context Protocol) server for @leejpsd/nextjs-cache-handler Redis caches. Lets AI agents (Claude Code, Cursor, …) inspect and operate a running deployment's Next.js cache: *"why isn't this page updating?"* becomes a tag_state call instead of guesswork.

Setup

Project .mcp.json (Claude Code picks this up automatically):

{

"mcpServers": { "nextjs-cache": { "command": "npx", "args": ["-y", "@leejpsd/nextjs-cache-handler-mcp"], "env": { "REDIS_URL": "redis://127.0.0.1:6379", "DEPLOYMENT_VERSION": "your-deploy-id" } } } }

Runs locally over stdio and connects to YOUR Redis — nothing is hosted.

AWS/ElastiCache note: ElastiCache is VPC-internal, so a locally

running MCP server needs an SSH tunnel/bastion (point REDIS_URL at the

tunnel). Agents running inside the VPC (CI, in-cluster) connect directly.

Pair with the AWS agent skills/MCP: they handle the infrastructure, this

server handles cache semantics.

Tools

ToolWhat it answersWrites?
cache_healthIs Redis up? What's cached, per layer/kind?no
cache_searchWhich keys match this pattern?no
cache_inspectDecode one entry: kind, age, tags, TTL, compression, sizesno
tag_stateIs this tag invalidated right now, on BOTH cache layers?no
explain_keyParse a raw Redis key into layer/kind/namespace/keyno
simulate_swrWould this entry be fresh / stale / expired, and what happens on read?no
invalidate_tagSoft (SWR) or hard invalidation — dry-run unless `confirm: true`gated

Env: REDIS_URL (required), DEPLOYMENT_VERSION (recommended — scopes namespace-aware tools), CACHE_KEY_PREFIX / ISR_KEY_PREFIX (only when the handlers use custom prefixes).
