Notes

  • Works on standard HTML sites (Shopify, WooCommerce, static pages)

  • JavaScript-heavy SPAs may need a headless browser (Playwright) upgrade

  • Cache persists across restarts via monitor_cache.json

  • 100% free: no third-party APIs, no paid data sources

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
