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 — Packages with similar functionality + their sizes (for migration planning).
• history — Compare size across recent versions (fetches each version sequentially — slow for large lists).
• recent_searches — What other people have recently been measuring on bundlephobia.com.
