Use when comparing or auditing packages. license: MIT --- # npm Package Research via MCP Use this skill for in-depth npm package research: bundle sizes, vulnerability scanning, download comparisons, and dependency trees. No API keys needed. ## Available Tools | Tool | What it does | |------|-------------| | `search` | Search npm packages by query | | `package_info` | Detailed info: description, license, repo, dependencies | | `downloads` | Download stats for a package | | `compare_downloads` | Compare download counts across multiple packages | | `bundle_size` | Bundle size (minified + gzip) via Bundlephobia | | `vulnerabilities` | Known vulnerability info and advisory links | | `dependency_tree` | Show direct dependencies as a tree | | `download_trends` | Daily breakdown with sparkline visualization | ## Workflow 1. For "which library?" questions: `compare_downloads` + `bundle_size` for each candidate 2. For security audits: `vulnerabilities` on each dependency 3. For adoption analysis: `download_trends` to see growth patterns 4. For dependency footprint: `dependency_tree` before adding a new package ## Key Patterns - `bundle_size` calls Bundlephobia — some packages may not be analyzable (native modules, very large packages) - `compare_downloads` accepts multiple package names — ideal for "zustand vs jotai vs valtio" comparisons - `vulnerabilities` checks npm audit advisories — always run this before recommending a package - `download_trends` includes a text sparkline for quick visual trend assessment
