Overview

MCP server for TERMDAT, the terminology database of the Swiss Federal Administration, maintained by the Federal Chancellery. It gives an AI agent the officially validated designations of Swiss authorities, departments and legal acts across DE / FR / IT / EN — with source references and validation status.

Discovered through i14y-mcp, which catalogues TERMDAT as data service ff0c37eb-2f7c-4ff6-996e-d22b77bf52fc.

What this is — and what it is not. TERMDAT is not a subject dictionary. It is a certified name-plate archive: it will not tell you what «Sonderpädagogik» means, but it will tell you the official name of the authority responsible for it, and what that authority is called in French.

Measured coverage (live, 2026-07-19, German search over the Terminus field):

The thirteen «Bildung» hits are organisational names — Bildungsdirektion, Erziehungsdepartement, Departement für Volkswirtschaft und Bildung — not pedagogical concepts. Plan accordingly: this server is strong for authority naming, official titles and abbreviations, and largely silent on domain vocabulary.

Features

• Seven read-only tools over the official TERMDAT public v2 API.
• Official designations across DE / FR / IT / EN, with source reference and validation status on every response.
• Communication QA: check up to 25 terms in one call against validated designations.
• Vocabulary cache (24 h TTL) for the 140 collections and 23 classifications, with stale-serve fallback.
• Retry with exponential backoff (2/4/8 s); explicit MaxEntryCount to avoid silent truncation.
• Dual transport: stdio (local) and Streamable HTTP (cloud). Both serve MCP protocol revision 2026-07-28.
• No authentication required — public, unauthenticated API (No-Auth-First).
