Swiss Health MCP Server

An MCP server that gives AI assistants structured access to 1.6 million Swiss health insurance premium records -- 55 insurers, 26 cantons, 11 years of official government data.

Built on the Model Context Protocol. Data sourced from BAG Priminfo (Swiss Federal Office of Public Health, 2016--2026). This is the MCP companion to the KrankenkassenGPT REST API.
