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": {
    "npm-plus": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-npm-plus"
      ]
    }
  }
}

Run this in your terminal

claude mcp add npm-plus -- npx -y mcp-server-npm-plus

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "npm-plus": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-npm-plus"
      ]

Common questions

Is Npm Plus 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 (1.0.1) reached the registry 8 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?

mcp-server-npm-plus

npm package research from your AI assistant. Search packages, check bundle sizes, scan for vulnerabilities, compare download counts, and inspect dependency trees. No API keys needed.

npx mcp-server-npm-plus

Works with Claude Desktop, Cursor, VS Code Copilot, and any MCP client. Uses public npm registry APIs.

Demo built with remotion-readme-kit

Why

Choosing between npm packages usually means opening a bunch of browser tabs: npm for package info, Bundlephobia for size, Snyk for vulnerabilities, npm trends for download comparisons. This server puts all of that in one place, accessible through your AI assistant. Ask "compare zustand vs jotai vs valtio" and get download numbers, bundle sizes, and dependency counts side by side. Ask "are there any known vulnerabilities in express?" and get the answer without leaving your editor. It uses only public npm APIs, so there's nothing to sign up for.

Tools

Tool	Description
`search`	Search npm packages by query
`package_info`	Get detailed info: description, license, repo, dependencies

`download_trends`	Daily breakdown with sparkline

Quick Start

Cursor

Add to .cursor/mcp.json:

"mcpServers": { "npm-plus": { "command": "npx", "args": ["mcp-server-npm-plus"] } } }
