Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

gladius-mcp

MCP browser-use server: a native Rust binary driving the owned pinned Chromium (chrome-headless-shell) over CDP, served over stdio. This package is a dependency-free Node launcher plus a pinned browser/runtime manifest — it contains no browser bytes and no server bytes.

Run

npx gladius-mcp@latest

Or pin it in an MCP client as a stdio server with command npx and args ["gladius-mcp@latest"].

First run provisions two things, both sha256-verified before and after extraction: the pinned server runtime from the tagged GitHub Release into %LOCALAPPDATA%\gladius\engine\<serverVersion>-<bundleSha8>\, and the pinned browser from Google's Chrome-for-Testing endpoint (~118 MB download) into %LOCALAPPDATA%\gladius\chromium\<version>-<zipSha8>\. Both are reused on later runs (re-verified each time); any mismatch refuses and writes nothing. An explicit GLADIUS_CHROMIUM binary wins instead: on that path no browser is provisioned at all. All launcher chatter goes to stderr; stdout belongs to the MCP channel.

Diagnostics (no network)

npx gladius-mcp@latest --doctor

Prints the pinned manifest and the resolved cache paths, exits 0, performs no fetch. --print-manifest is an alias.

Overrides

Use npx gladius-mcp@latest; a pinned version is only installable while its GitHub release exists; the one-release policy deletes older releases.

Requirements

  • Windows x86_64. Any other platform refuses at startup (override for diagnostics only: GLADIUS_MCP_ALLOW_NON_WINDOWS=1).
  • Node.js >= 22.14.0 (global fetch plus crypto/zlib builtins only; zero dependencies).

Browser provenance

The browser is Chrome-for-Testing chrome-headless-shell 155.0.8059.84 (headless-only), fetched at provision time from https://storage.googleapis.com/chrome-for-testing-public/155.0.8059.84/win64/chrome-headless-shell-win64.zip. It is NEVER redistributed in our release assets or this package: our own manifest is the integrity root (CfT publishes no hashes), and the in-package manifest pins the archive hash, the extracted tree's file count + total size, and every per-file sha256. The runtime bundle carries the Chromium licence attribution copy (THIRD-PARTY-LICENSES/LICENSE.headless_shell).
