Packagephobia MCP — measures the size an npm package takes up on disk after install (publish-size + install-size including all transitive deps). Complements bundlephobia, which measures runtime bundle size. Keyless.

Tools

  • size(package, version?) — install + publish size for an npm package

Why bother?

Bundle size ≠ install size. A package can be tiny at runtime but pull in heavy dev/transitive deps that slow CI cache hydration. packagephobia measures the full node_modules footprint.
