gr-scraper-mcp

MCP server that tracks live board game inventory on thegamerules.com. On each run it scrapes the full catalogue, diffs it against the last stored snapshot, and reports what was added and what was removed. Deployed on Render, backed by Upstash Redis, with a Telegram bot interface.

How it works

Puppeteer launches a headless Chromium browser and visits the product listing pages
Images, fonts, stylesheets, and tracking scripts are blocked to speed up rendering
The scraper waits for .name elements to appear, then collects all game titles
The live list is compared against the snapshot stored in Redis
Added and removed games are returned, and the snapshot is updated
