Swiss Health Mcp

Swiss Health MCP Server

[npm version] [License: MIT]

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.

Quick Start

Add this to your Claude Desktop config (claude_desktop_config.json) or Cursor settings (.cursor/mcp.json):

{  "mcpServers": {    "swiss-health": {      "command": "npx",      "args": ["-y", "@prinz_esox/swiss-health-mcp"],      "env": {        "SUPABASE_URL": "https://your-project.supabase.co",        "SUPABASE_SERVICE_ROLE_KEY": "your-service-role-key"      }    }  }}

Or install globally:

npm install -g @prinz_esox/swiss-health-mcp

The server is also available on the Smithery registry and the MCP Registry.

Data

All data comes from BAG Priminfo, the official database of the Swiss Federal Office of Public Health.

Features

• Intelligent insurer name resolution -- fuzzy matching across 55+ insurers and their sub-brands. Ask for "Helsana" and the server resolves all associated insurer IDs automatically.
• Automatic disclaimer -- every response includes BAG Priminfo attribution and a notice that premiums are informational only.
• Read-only access -- no write operations, no personal data.
• Percentage change calculations -- price history includes year-over-year trends.

Example Prompts

"What are the cheapest health insurers in Zurich for 2026?"
