Overview

AI-generated overview

Local MCP server that lets an assistant look up npm package bundle sizes from Bundlephobia, with no API key required.

What you can do
  • Look up npm package bundle sizes from Bundlephobia.
  • The manifest lists no individual tools, so the exact operations are not documented; expect size and dependency-related lookups for npm packages.
  • No authentication is declared, so queries need no key.
When to use it
Useful when you are choosing between npm dependencies and want an assistant to check how large a package is before adding it, or to compare the footprint of a few candidate libraries.
Requirements
Runs as a local process over stdio, installed from the npm package @mrfentmen/bundlephobia-mcp, so Node.js and npm are needed. No environment variables, headers or accounts are declared. Network access to Bundlephobia is implied by the service it queries.
Before you install
The README and tool list are not available, so the exact commands and data sent per query cannot be verified. Package names you ask about are sent to the third-party Bundlephobia service. Desktop-only; it cannot be used from a web client.

Installation

In SourceWeft

  1. Open Bundlephobia Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
