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 🙏

dendro-react-mcp

v0.9.0

Published

React codebase semantics for AI agents — component contracts, blast radius, rerender risk, effect hygiene, navigation graphs, health audits — plus a VS Code visualizer you both share. Free, local-only.

Readme

dendro-react-mcp

The standalone MCP server from Dendro React — 36 free tools that give AI agents deep visibility into React and React Native codebases. Analysis runs locally; your code never leaves your machine.

  • Component trees, per-component complexity scores, prop flow, reverse dependency graphs
  • Re-render risk detection that understands React Compiler, Server Components, and React 19
  • Navigation graphs: React Navigation, Expo Router, Next.js App & Pages Router, Remix, React Router
  • Context maps, hook dependency analysis, circular dependency detection
  • Live runtime introspection via React DevTools (inspect and modify a running app's state)
  • AI-controlled visualization + guided workflow audits (requires the VS Code extension, also on Open VSX for Cursor/Windsurf)

Setup

Add to your MCP client config (Claude Code, Cursor, etc.):

{
  "mcpServers": {
    "dendro-react": {
      "command": "npx",
      "args": ["-y", "dendro-react-mcp"]
    }
  }
}

The server treats its working directory as the workspace root. To point it elsewhere (or to restrict file access explicitly), set the DENDRO_WORKSPACE_ROOT environment variable.

First call to make: get_usage_guide — returns the full tool index, sequencing rules, and the running build's version stamp.

Notes

  • The visualization (open_visualizer, visualize_*) and sidebar features light up when the Dendro React VS Code extension is installed and running; every analysis tool works standalone.
  • All 36 tools are free. No account, no license key.
