A powerful Model Context Protocol (MCP) server that revolutionizes NPM package analysis through AI. Built to integrate with Claude and Anthropic AI, it provides real-time intelligence on package security, dependencies, and performance. This MCP server delivers instant insights and smart analysis to safeguard and optimize your npm ecosystem, making package management decisions faster and safer for modern development workflows.

## Features

- **Version analysis and tracking**
- **Dependency analysis and mapping**
- **Advanced Security Scanning**: Recursive dependency checks, ecosystem awareness (e.g., React), and accurate version resolution.
- **Strict Input Validation**: Protection against Path Traversal, SSRF, and Command Injection via rigorous input sanitization.
- **Package quality metrics**
- **Download trends and statistics**
- **TypeScript support verification**
- **Package size analysis**
- **Maintenance metrics**
- **Real-time package comparisons**
- **Standardized error handling and MCP response formats**
- **Efficient caching for improved performance and API rate limit management**
- **Rigorous schema validation and type safety using Zod**

Note: The server provides AI-assisted analysis through MCP integration.

## Caching and Invalidation

To ensure data accuracy while maintaining performance, the server implements robust caching strategies:
- **Automatic Invalidation**: The cache is automatically invalidated whenever `pnpm-lock.yaml`, `package-lock.json`, or `yarn.lock` changes in your workspace. This ensures you always get fresh data after installing or updating dependencies.
- **Force Refresh**: All tools accept an optional `ignoreCache: true` parameter to bypass the cache and force a fresh lookup from the registry.

### Example Usage (JSON-RPC)

When calling a tool, simply include `ignoreCache: true` in the arguments:

```json
{
  "name": "npmVersions",
  "arguments": {
    "packages": ["react"],
    "ignoreCache": true
  }
}
```

## Installation

### Migration to HTTP Streamable

This MCP server now supports both STDIO and HTTP streamable transport. Your existing STDIO configuration will continue to work without changes.

**New capabilities:**
- HTTP streamable transport via Smithery.ai
- Enhanced scalability and performance
- Interactive testing playground

**Development commands:**
```bash
# Development server with playground
npm run dev

# Build for HTTP
npm run build:http

# Start HTTP server
npm run start:http
```
