## Description
npm intelligence — search packages, check bundle sizes, scan vulnerabilities, compare downloads.

## Tools
Capabilities this server exposes over MCP:

- **search** — Search npm packages by query. Returns name, version, description, and keywords.
- **package_info** — Get detailed info about an npm package: description, license, repo, dependencies.
- **downloads** — Get download statistics for an npm package.
- **compare_downloads** — Compare download counts across multiple packages.
- **bundle_size** — Get bundle size (minified + gzip) for an npm package via Bundlephobia.
- **vulnerabilities** — Get vulnerability info for an npm package. Note: Full audit requires npm audit in project context.
- **dependency_tree** — Get dependency tree for an npm package (direct deps only).
- **download_trends** — Get download trends (daily breakdown + sparkline) for an npm package.

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

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

## Documentation

## What ofershap/mcp-server-npm-plus MCP server does

ofershap/mcp-server-npm-plus MCP server connects an MCP-compatible AI assistant to public npm registry APIs and Bundlephobia. It brings common package evaluation tasks into the assistant rather than requiring separate searches across npm, download-statistics pages, bundle-size services, and vulnerability sources.

The server supports package discovery and comparison. You can search npm by query, inspect a package’s description, license, repository, and dependencies, or compare download counts for multiple packages. It also exposes package-level download statistics and daily download trends with a sparkline.

## Tools and capabilities

Available MCP tools include:

- `search` for finding npm packages by query.
- `package_info` for package descriptions, licenses, repositories, and dependencies.
- `downloads` for download statistics for one package.
- `compare_downloads` for comparing counts across multiple packages.
- `bundle_size` for minified and gzip sizes through Bundlephobia.
- `vulnerabilities` for vulnerability information and advisory links.
- `dependency_tree` for displaying direct dependencies as a tree.
- `download_trends` for daily download data with a sparkline.

These tools support questions such as finding React state-management packages, checking lodash’s bundle size, comparing zustand with jotai and valtio, or reviewing known issues in express.

## Setup and configuration

Install and launch ofershap/mcp-server-npm-plus MCP server with npx:

```bash
npx mcp-server-npm-plus
```

For Cursor, add a server entry to `.cursor/mcp.json` with `npx` as the command and `mcp-server-npm-plus` as its argument. Claude Desktop uses the same command and argument in `claude_desktop_config.json`. In VS Code, configure the command through an MCP extension.

No API keys or sign-up are required according to the project documentation. The server uses public npm APIs, with Bundlephobia used for bundle-size results.

## Limitations and notes

The documented data sources are public npm APIs and Bundlephobia, so the server is intended for package research based on the information those services provide. The dependency-tree capability is described as showing direct dependencies, not a complete transitive dependency graph.

The repository identifies the project as MIT licensed and provides development commands for installing dependencies, type-checking, building, testing, linting, and formatting. Those commands are relevant for contributors; normal use is shown through the npx launch command.
