What is the Npm Sentinel MCP Server?

Npm Sentinel MCP lets Claude, Cursor and other MCP clients work with Npm Sentinel MCP directly. NPM Sentinel MCP - 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.

What Npm Sentinel MCP does

A powerful Model Context Protocol (MCP v2) server built on @modelcontextprotocol/server and @modelcontextprotocol/core (v2) that revolutionizes NPM package analysis through AI. Built to integrate seamlessly with Claude, Anthropic AI, and any MCP v2 compatible client, it provides real-time intelligence on package security, dependencies, and performance.

Key capabilities

  • MCP v2 Native Protocol — Fully upgraded to MCP v2 with outputSchema Zod validation, dual structuredContent returning, and diagnostic context logging (ctx.mcpReq.log)
  • Self-Contained Vector Icons — Pre-configured SVG Data URIs (data:image/svg+xml) embedded across all 19 tools, resources, and prompts for enhanced client UI presentation
  • Advanced Security Scanning — Recursive dependency checks powered by Google's deps.dev and OSV.dev, ecosystem awareness, and accurate version resolution
  • Smart Alternatives Filtering (npmAlternatives) — Intelligent search based on functional domain keywords with strict ecosystem plugin/extension filtering (e.g., excludes express-rate-limit when searching for alternatives to express)
  • Dependency & Transitive Mapping — Complete dependency tree analysis mapping through deps.dev
  • Package Quality & Maintenance Metrics — Real-time scoring using OpenSSF Scorecard, GitHub repository metrics, and npms.io
  • Download Trends & Performance — Real-time download statistics and bundle size analysis
  • Smart SemVer Shorthand & Range Resolution — Transparently resolves major version shorthands, prefixes, and ranges (e.g., express@2, express@v4, zod@3.x, react@^18, lodash@~4.17) to the highest matching release without failing on missing exact version keys

Practical notes

  • Maintained by Nekzus, written in TypeScript.
