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

For "which library?" questions: compare_downloads + bundle_size for each candidate
For security audits: vulnerabilities on each dependency
For adoption analysis: download_trends to see growth patterns
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
