Overview

Description from the maker (original English)

Use passwords and API keys from your KeyZula vault without the assistant seeing them.

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: Other
  • You need to fill in: KEYZULA_SERVICE_TOKEN

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: KEYZULA_SERVICE_TOKEN, KEYZULA_MCP_ALLOW_REVEAL

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": {
    "keyzula": {
      "command": "npx",
      "args": [
        "-y",
        "@keyzula/cli",
        "mcp"
      ],
      "env": {
        "KEYZULA_SERVICE_TOKEN": "your-value",
        "KEYZULA_MCP_ALLOW_REVEAL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add keyzula --env KEYZULA_SERVICE_TOKEN=your-value --env KEYZULA_MCP_ALLOW_REVEAL=your-value -- npx -y @keyzula/cli 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": {
    "keyzula": {
      "command": "npx",
      "args": [
        "-y",
        "@keyzula/cli",
        "mcp"
      ],
      "env": {
        "KEYZULA_SERVICE_TOKEN": "your-value",
        "KEYZULA_MCP_ALLOW_REVEAL": "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": {
    "keyzula": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@keyzula/cli",
        "mcp"
      ],
      "env": {
        "KEYZULA_SERVICE_TOKEN": "your-value",
        "KEYZULA_MCP_ALLOW_REVEAL": "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

  • KEYZULA_SERVICE_TOKEN secret env
    Optional service account token (kzsa_1_…). Without it, the server uses your unlocked `keyzula ssh-agent`.
  • KEYZULA_MCP_ALLOW_REVEAL env
    Set to true to offer read_secret; every request still needs approval in a window on your computer.

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

What it can do

Common questions

Is KeyZula 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: KEYZULA_SERVICE_TOKEN

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 (1.2.4) reached the registry yesterday.

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?

KeyZula MCP server

Let GitHub Copilot, Claude, Cursor and other AI assistants use the passwords, API keys and tokens in your KeyZula vault without the values ever entering the conversation.

The assistant finds items by name, website or username and passes secrets to the programs it runs through kz:// references. Values go into the environment of a command (concealed in its output) or into a file only you can read. The assistant receives names and references, never the secrets themselves.

This repository holds the documentation and registry metadata for the server. The server is part of the KeyZula command-line tool, published on npm and Homebrew.

Tools

ToolWhat it doesWhat the assistant receives
search_itemsSearches your vault by name, username, website or folderNames, locations, usernames, websites and kz:// references, never values
run_commandRuns a command with secrets in its environment variablesExit code and output, with secret values concealed
inject_templateFills a {{ kz://… }} template and writes a file only you can readOnly the file path
generate_passwordGenerates a strong password or passphraseThe generated value (not saved)
vault_statusShows whether KeyZula is signed in and unlockedStatus
read_secretShows one value, such as a 2FA codeOff by default; when turned on, every request needs your approval in a window on your computer

Requirements

  1. A KeyZula account (free).
  2. The KeyZula command-line tool, signed in and unlocked once in a terminal:
npm i -g @keyzula/cli        # or: brew install keyzula/tap/keyzula

keyzula login keyzula ssh-agent --daemon

The MCP server reads only from this unlocked agent and never asks for your master password. It runs on macOS, Linux and Windows.

Configuration

VS Code and GitHub Copilot

Install from the MCP server gallery in VS Code, or add it to .vscode/mcp.json (or your user mcp.json):

{

"servers": { "keyzula": { "type": "stdio", "command": "npx", "args": ["-y", "@keyzula/cli", "mcp"] } } }

If you installed the CLI globally, you can use "command": "keyzula", "args": ["mcp"] instead. Desktop apps may not see your terminal's PATH; use the full path from which keyzula (Windows: where keyzula) if needed.

Claude, Cursor, Windsurf and other clients

Most clients use the mcpServers format:

{

"mcpServers": { "keyzula": { "command": "npx", "args": ["-y", "@keyzula/cli", "mcp"] } } }

Claude Code: claude mcp add keyzula -- npx -y @keyzula/cli mcp. For Claude Desktop, a one-click extension is available at keyzula.com/en/ai.

Options
SettingFlagEnvironment variable

Ask before every command or file that uses a secret--confirmKEYZULA_MCP_CONFIRM=true
Limit the assistant to an organization's service accountKEYZULA_SERVICE_TOKEN=kzsa_1_…

Usage

Ask in plain language; the assistant picks the right item and tool:

  • "Deploy with the Cloudflare API token from KeyZula."
  • "Run the database migrations using the staging Postgres password."
  • "Create a .env file for this project from my KeyZula items."
  • "Which KeyZula items do I have for AWS?"

For example, run_command can run wrangler deploy with CLOUDFLARE_API_TOKEN set to kz://~/Cloudflare/password (~ is your personal vault). The command gets the value; the assistant sees only the reference and the command's output, with the value concealed.

Privacy and control

  • Vault data is end-to-end encrypted; the server never sees it in plain text. The MCP server talks to the KeyZula agent on your computer over a private local socket.
  • Every use appears in your access log as "Used by an AI assistant" (item, action and time, never the value).
  • Lock the vault at any time with keyzula lock; the assistant then has no access until you unlock it.
  • Nothing is sent to the AI provider or any third party by the server itself.
