Bundlephobia MCP — bundle-size analysis for npm packages. Reports minified + gzipped size, tree-shakeability, dependency count, build time estimates. Keyless.

Tools

• size(package, version?) — bundle size for package (or package@version)
• similar(package, version?) — packages with similar functionality + their sizes
• history(package, version?) — size history across versions (heuristic: queries each version)
• recent_searches() — what other people have been measuring

Notes

Bundlephobia is rate-limited and sometimes slow on first request (it builds + measures the package on demand). Subsequent requests for the same package@version are cached.

Tools

• size — Bundle size analysis — minified + gzipped, tree-shakeability, dependencies, esm/cjs detection.
• similar — Return npm packages with similar functionality to the given package, each with their minified + gzipped bundle sizes, to aid migration or replacement decisions.
• history — Fetch minified + gzipped bundle size for each of up to 5 specified versions of an npm package and return them side-by-side for size regression tracking.
• recent_searches — Return the list of npm packages most recently measured on bundlephobia.com, showing current community interest in bundle-size analysis.
