Ask before you scrape: is a site open, may I fetch this URL, and how do I extract a page. No key.

Yes, most likely. Open source and no paid account or API key is mentioned in the listing. Check the provider for current pricing.

Remote. Hosted by the provider. You connect with a URL, nothing to install.

Run: claude mcp add --transport http rat-radar https://rat-radar.github-a18.workers.dev/mcp
