Tools

Tool	Description
`size`	Return the publish size and full install size (including dependencies) in bytes for an npm package name and optional version via packagephobia.com.

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 965+ 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.
