@pipeworx/packagephobia
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.
Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.
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.
Data source
https://packagephobia.com/v2/api.json?p=<pkg>[@version]
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"packagephobia": {
"url": "https://gateway.pipeworx.io/packagephobia/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 1394+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Packagephobia data" })
The gateway picks the right tool and fills the arguments automatically.
