Environment variables
  • REGISTRUM_API_KEYsecretOptional. Without it the server uses the keyless hosted endpoint https://registrum.co.uk/api/mcp, which has daily caps. A free key gives 60 days of full access (every endpoint, no monthly cap, no card), then stays free for light use. Get a free key at https://registrum.co.uk/?utm_source=mcp&utm_campaign=registry

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
