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 🙏

Build proven high converting product showrooms and websites from your existing ecommerce catalog

Readme

Mantis MCP Server

AI assistant tools for building high-converting immersive commerce showrooms from your existing e-commerce catalog. Built on Mantis's production immersive-commerce platform, used by Fortune 500 brands including New Balance, with deployments spanning the Paris 2024 Olympics, MLB, NHL, and the Premier League.

Part of Mantis's vision for agent-invoked immersive commerce infrastructure. Learn more at mantisxr.com.

Quick Start

npx mantis-mcp

Or install globally:

npm install -g mantis-mcp

Then configure in Claude Desktop, Cursor, or any MCP-compatible client (see Configuration below).

Status

The Mantis showroom platform this MCP connects to is live in production, used by Fortune 500 brands including New Balance, with deployments including the Paris 2024 Olympics, Chicago Cubs (MLB), St. Louis Blues (NHL), and Burnley FC and other Premier League clubs. This MCP server is how that platform gets exposed to AI agents, and it's actively in development. Some tools are fully wired to the real platform API today; others are simulated while backend endpoints are being built out. See the tool status below for exactly what's real versus in progress.

Setup

Environment Variables (Optional)

Configure these to connect to the real Mantis API:

MANTIS_API_URL=https://your-mantis-instance.com
MANTIS_AUTH_TOKEN=your_token_here

Mantis users receive their API URL and auth token during account setup. Without these, tools work with simulated data for code generation and planning.

Configuration

Claude Desktop:

  1. Open Settings → Developer → Edit Config
  2. Add:
{
  "mcpServers": {
    "mantis-mcp": {
      "command": "npx",
      "args": ["mantis-mcp"]
    }
  }
}

Cursor:

  1. Settings → MCP Servers → Add new server
  2. Configure with npx mantis-mcp

Other MCP clients: Use npx mantis-mcp or node /path/to/dist/index.js

Tools

✅ Fully Working (no API required)

installMantisSDK Generates installation commands and .npmrc setup for integrating Mantis SDK into React, Vue, Next.js, Shopify, or vanilla JavaScript projects.

createMantisIntegration Generates complete, framework-specific integration code with event handlers, cart integration, and analytics tracking.

generateEventHandler Creates event handler code for Mantis SDK events (cart-opened, model-click, variant-changed, etc.).

analyzeConsoleErrors Pattern-matches common errors (SDK not loaded, postMessage blocked, WebGL issues) and provides fixes with code examples.

checkBrowserCompatibility Checks browser compatibility for WebGL, postMessage, fullscreen, and other immersive features with polyfill recommendations.

🟡 Partially Working (uses real API when configured)

validateSetup Validates Mantis SDK installation. Calls real showrooms.getShowroom API if MANTIS_API_URL is configured, otherwise returns sample validation checks.

importCatalog Imports product catalogs from Shopify (real API), CSV, or manual input. Data parsed successfully; backend storage endpoints pending.

createStore Creates an immersive showroom. Attempts real showrooms.createShowroom API call if configured, falls back to mock response with guidance.

publishStore Publishes showroom live. Attempts real showrooms.updateShowroom API if configured, otherwise simulates status change to active.

🔴 Mocked (simulated data, backend endpoints pending)

debugPostMessage Simulates postMessage debugging scenarios with realistic message timelines, origin checks, and error patterns.

testMantisEvent Simulates SDK event testing (model-loaded, add-to-cart, etc.) with validation and performance timing.

simulateUserFlow Simulates multi-step user interaction flows (load → click → add-to-cart) with realistic delays and error scenarios.

getPerformanceMetrics Generates simulated performance data (FPS, load times, memory, GPU) based on requested metrics.

analyzeEventFlow Simulates event flow analysis with conversion funnels, dropoff points, and user behavior patterns.

What This MCP Does Not Do

Immersive Asset Generation: Mantis does not provide automated conversion of product photos into immersive-ready assets. Merchants must provide immersive-ready assets (.glb/.gltf files) when creating products. This is an intentional scope decision: automated asset generation is a commoditizing service layer that multiple companies have attempted without building sustainable businesses. Mantis's value is the immersive showroom platform, merchandising intelligence, and agent-invokable commerce infrastructure—not asset generation.
