Liffey Metals MCP server

A public, read-only Model Context Protocol server for AI assistants. It publishes the same prices and information as liffeymetals.com: the net price per gram Liffey Metals pays for gold, silver and platinum, and how selling by insured post from anywhere in Ireland works.

No account, no key, no personal data. The server stores nothing and holds no credentials; its only data source is the public price feed at https://liffeymetals.com/api/public/prices.
