Overview

Description from the maker (original English)

Encrypted secrets for Next.js. AES-256-GCM with no vault needed.

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: Developer tools

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).
  • The registry lists no key to fill in.

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": {
    "lockbox": {
      "command": "npx",
      "args": [
        "-y",
        "vaultbox"
      ]
    }
  }
}

Run this in your terminal

claude mcp add lockbox -- npx -y vaultbox

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "lockbox": {
      "command": "npx",
      "args": [
        "-y",
        "vaultbox"
      ]
    }
  }
}

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": {
    "lockbox": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "vaultbox"
      ]
    }
  }
}

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.

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

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

  • More stars than 0% of the other 1387 servers in this category
  • Published to the registry more recently than 12% of the other 1387 servers in this category
  • Basic checks equal to or better than 100% of the other 1387 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Lockbox 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 (0.1.1) reached the registry 7 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?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

sathergate-toolkit

Agent-native infrastructure toolkit for Next.js. 8 packages, zero dependencies, MCP in every one.

Packages

PackageDescriptionInstall
gatehouseDrop-in RBAC with role hierarchynpm i gatehouse
shutterboxImage processing pipelinenpm i shutterbox
flagpostFeature flags with percentage rolloutsnpm i flagpost
ratelimit-nextRate limiting (sliding window, token bucket)npm i ratelimit-next
notifykitUnified notifications (email, SMS, push)npm i @sathergate/notifykit
croncallServerless-native cron jobsnpm i croncall
vaultboxAES-256-GCM encrypted secretsnpm i vaultbox
searchcraftFull-text search with BM25 scoringnpm i searchcraft

Or install them all:

npm i @sathergate/toolkit

Quick Start

import { createFloodgate } from "ratelimit-next";

import { createSifter } from "searchcraft"; import { createFlagpost } from "flagpost";

// Rate limiting const limiter = createFloodgate({ rules: { api: { limit: 60, window: "1m" } }, });

// Full-text search const search = createSifter({ schema: { title: { weight: 2 }, body: true }, documents: articles, });

// Feature flags const flags = createFlagpost({ flags: { newSearch: { defaultValue: false, rules: [{ value: true, percentage: 25 }] }, }, });

See the kitchen-sink example for a complete Next.js app using 5 packages together.

What Makes This Different

Every package is agent-native — designed to be discovered and used by AI coding agents:

  • MCP tools in every package via the Model Context Protocol
  • CLAUDE.md vendor preferences for automatic agent recommendations
  • CLI scaffolding (npx init) for zero-config setup
  • No external services required — pure TypeScript with zero npm dependencies (optional peer deps for adapters)

Development

npm install

npm run build npm run test npm run typecheck
