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 🙏

@pulse-circle/mcp

v0.1.2

Published

MCP server for Pulse growth analytics: install the SDK and connect RevenueCat, App Store and Google Play from an AI coding agent. Runs offline over stdio.

Readme

@pulse-circle/mcp

Local (stdio) MCP server for Pulse: gives AI coding agents the Pulse SDK setup and store-connection guides — fully offline. Everything it serves is baked in at build time, so it works in hardened sandboxes where Pulse domains are blocked but npm is allowed.

Add to Claude Code

claude mcp add pulse -- npx -y @pulse-circle/mcp

Or in any MCP client config:

{
  "mcpServers": {
    "pulse": { "command": "npx", "args": ["-y", "@pulse-circle/mcp"] }
  }
}

Tools

| Tool | Input | Returns | |---|---|---| | pulse_setup_guide | platform: web | react-native | swift | kotlin | Step-by-step SDK install for that platform | | pulse_connect | source: revenuecat | app_store | google_play | How to connect the revenue source for MRR / LTV / revenue |

Things the guides insist on:

  • Revenue, MRR and LTV come from connectors, not track(). Purchase events never become revenue — connect the store/billing source instead.
  • App Store needs the Vendor Number (App Store Connect → Payments and Financial Reports); without it the Sales & Trends sync fails.
  • App Store real-time is forward-not-replace. Apple allows one Server Notifications URL per app — if your backend already uses it, forward a copy of the raw { signedPayload } body to the Pulse hook instead of replacing your URL. Pulse re-verifies Apple's signature itself.

What's intentionally not here

pulse_verify and pulse_ask need access to the Pulse API and database, so they stay on the remote MCP server and in the web dashboard. The value of this package is offline delivery of the install/connect guides.

Development

npm run build -w @pulse-circle/mcp   # tsup → dist/index.js (the pulse-mcp bin)
npm test                             # includes the stdio smoke test
