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

@dvcol/cdb-mcp

Node 24+ Model Context Protocol adapter for principal-scoped Chrome Debugger Bridge tools.

pnpm add @dvcol/cdb-mcp
import { createCdbToolSession } from '@dvcol/cdb-mcp';

Create one tool session per authenticated principal and dispose it with that principal. See the repository documentation for the authorization model.

Opt-in Node diagnostic channels keep execution details outside agent responses. cdb.mcp.action reports action phases, CDP command outcomes and dispatch boundaries. cdb.mcp.snapshot separates frame discovery, command round trips, artifact reads and formatting; command round trips include provider and transport time. cdb.mcp.hit-test reports element and ancestor-frame geometry and hit nodes for diagnosing coordinate mismatches. Treat hit-test records as private page diagnostics.

Page WebMCP

CDB exposes native main-document WebMCP through browser.list_webmcp_tools and browser.invoke_webmcp_tools. Discovery requires inspect access; invocation requires interact access and an exclusive lease. Extension hosts can configure discovery with defineProvider({ webMcp: { discovery: { include, exclude, enabled } }, ... }). Filters hide tools from discovery; they do not block direct invocation by name. See native page WebMCP for references, artifacts, cancellation, and configuration examples.
