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 🙏

Caching and memoization tools for AI agents — MCP server #30

Readme

MCP Server #30 — Caching and memoization tools for AI agents.

Analyze, generate, simulate, and optimize caching strategies across HTTP, CDN, and browser layers.

Tools

1. analyze_cache_headers

Analyze HTTP cache headers (Cache-Control, ETag, Last-Modified, Expires, Vary). Grades the overall caching strategy A+ through F and provides actionable improvement suggestions with context-aware advice for static assets, API responses, HTML pages, and media.

2. generate_cache_key

Generate deterministic cache keys from various inputs:

  • URL mode — normalizes URL, sorts query params, filters include/exclude params
  • Body mode — hashes request body with JSON key sorting for consistency
  • Composite mode — combines multiple key parts into a single deterministic hash

Supports namespacing, versioning, TTL, and outputs ready-to-use Redis/Memcached commands.

3. simulate_cache

Simulate cache behavior for a sequence of requests. Compare eviction strategies side-by-side:

  • LRU — Least Recently Used
  • LFU — Least Frequently Used
  • FIFO — First In, First Out
  • TTL — Time-To-Live based expiration

Outputs hit rate, miss rate, eviction count, and step-by-step timeline.

4. check_cdn_headers

Detect which CDN is serving a resource from response headers. Identifies Cloudflare, Fastly, Akamai, CloudFront, Vercel, Netlify, Google Cloud CDN, Azure CDN, KeyCDN, and Bunny CDN. Reports cache status (HIT/MISS/STALE/BYPASS), edge server, and POP location.

5. analyze_browser_cache

Analyze what resources a page would cache in the browser. Determines cache type (strong, heuristic, conditional, none), duration, revalidation strategy, and estimates bandwidth/time savings on repeat visits. Groups results by resource type with optimization suggestions.

Setup

npm install
npm run build
