What is Zefix Search?

Zefix Search is an unofficial MCP server for zefix.ch – the Switzerland Central Business Name Index.

How to use Zefix Search?

Install the .mcpb file on Claude Desktop or add the npx command to your MCP host config. Once configured, invoke the get_companies tool with parameters such as name_or_uid, cantons, legalForms, exactSearch, and phoneticSearch. The server runs over stdio and requires no authentication.

FAQ from Zefix Search

What is Zefix Search and how does it differ from the official zefix.ch website?

Zefix Search is an unofficial MCP server that provides the same search and detail functionality as the Zefix GUI but exposes it as a tool callable by AI assistants. It is not affiliated with or endorsed by the Federal Office of Justice.

Does the server require any API keys or authentication?

No. The server queries the public Zefix REST API at https://www.zefix.ch/ZefixREST/api/v1/ with no authentication required.

What runtime or host applications are required?

A host application that supports MCP and an LLM with tool-calling capabilities (e.g., Claude, GPT-4.1+, Gemini, Llama 3.1+). Node.js 24+ is optional and only needed for local development or running from source.

What transport protocol does Zefix Search use?

The server communicates over stdio using the standard MCP transport. It does not print anything to the terminal when run directly.

Where does the data come from and are there any usage limits?

All data comes from the public Zefix REST API. The server sends a custom User-Agent: zefix-mcp-unofficial header for transparency. Results are capped at 100 items per query.
