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.

OpenSecrets MCP

MCP server for OpenSecrets: money in U.S. politics. Needs a free API key.

Pairs well with fec-mcp, congress-gov-mcp, and govtrack-mcp.

Quick start

Get a key at https://www.opensecrets.org/api/ (free), then:

export OPENSECRETS_API_KEY=your_key_here
npm install
npm run build
node dist/index.js

The server uses stdio, so it can be connected to Claude Desktop, Cursor, VS Code, MCP Inspector, or another compatible MCP client.

Tools at a glance

search_candidates: Candidates by name with party/state/chamber.
candidate_summary: Raised, spent, cash, debt per cycle.

Limits and privacy

This project is intentionally narrow. It should be treated as a practical helper, not a complete certification or security audit. Check the implementation and the returned data before using it with sensitive material. Your key stays local and is only sent to OpenSecrets. Read-only.

Licence — no paywall

Every tool in this package is free: no licence key, no premium tier, no hosted licence gateway. The paywall machinery this repo once carried (per-tool licence checks and paid hosted endpoints) was removed repo-wide on 2026-10-17. Nothing that this package installs or calls asks you to pay.
