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 🙏

claude-fetch-setup

v0.1.2

Published

A tool to automatically setup fetch MCP and configure global CLAUDE.md for Claude Code in enterprise environments

Readme

Claude Fetch Setup

Background

This tool was inspired by the discussion in Issue #1217 and provides an automated solution for users experiencing "Domain not allowed" errors.

Error Example:

⏺ Fetch(https://zod.dev/v4)…
⎿ Error: Domain zod.dev is not allowed to be fetched

Solution

This tool bypasses this limitation by automatically setting up fetch-mcp as a custom MCP server, providing stable network fetch functionality.

Quick Installation

One-click install (Recommended)

npx claude-fetch-setup

Global installation

npm install -g claude-fetch-setup
claude-fetch-setup

After installation

After installation, run the following command to verify that fetch-mcp has been successfully added to your MCP list:

claude mcp list
cat ~/.claude/CLAUDE.md

How it works

This tool automatically performs the following steps to solve the domain fetch problem:

  1. ✅ Check and create ~/.claude-custom-mcp/ directory
  2. 📦 Clone the fetch-mcp repository
  3. 📦 Run npm install and npm run build to build the MCP server
  4. ⚙️ Automatically configure Claude Code: claude mcp add fetch node ~/.claude-custom-mcp/fetch-mcp/dist/index.js --scope user
  5. 📝 Configure global CLAUDE.md file in ~/.claude/ directory to ensure fetch-mcp is used instead of built-in fetch tools
