bag-health-mcp

Part of the Swiss Public Data MCP Portfolio — connecting AI models to Swiss public data sources.

🇩🇪 Deutsche Version

MCP server for Swiss public health data. Its core is the Swiss Federal Office of Public Health (BAG) Infectious Disease Dashboard (IDD) — epidemiological surveillance for 51 pathogens (influenza, COVID-19, measles, wastewater surveillance, and more) — extended with a multi-source health-indicator layer over the Swiss Health Observatory (Obsan), the Versorgungsatlas (health-care supply atlas, with cantonal series) and Sucht Schweiz (HBSC youth survey). All read-only, public Open Government Data.

🎯 Anchor demo query — «Wie hat sich der Alkoholkonsum bei 15-Jährigen im Kanton Zürich seit 2010 entwickelt, und wie steht der Kanton im Schweizer Vergleich da?» The HBSC youth series (via Obsan) answers the Switzerland-wide trend since 2010 with 95% confidence intervals. This particular indicator is national only, so the response includes a region_note saying so (HBSC is not cantonally representative). Most other Obsan indicators are published by canton — see the note on cuts below. These are aggregated population statistics — not individual advice. See docs/tool-design-health-indicators.md.

Tools

Infectious-disease surveillance (BAG IDD):

Health indicators — Obsan, Versorgungsatlas & Sucht Schweiz (multi-source):

⚠️ Aggregated population statistics only. The indicator tools serve population-level aggregates (prevalences/metrics by age/sex/region) — not individual advice, diagnosis or case assessment, and no personal data. This is stated in both tool descriptions and every response (aggregate_statistics_notice), and matters especially for suchtschweiz (HBSC), which touches prevention topics in a school context. Sources: Obsan ind.obsan.admin.ch (clean JSON API); Sucht Schweiz HBSC via the Obsan mirror (national); Versorgungsatlas returns a cantonal year/value series (26 cantons + a CH national total, with 95% CIs and a canton-vs-CH ratio) from the Tarifpool. See the per-source probe notes.

Obsan publishes an indicator in several cuts, not one series. Measured over 60 catalogue entries on 2026-08-08: 50 have a cantonal cut (kg), 49 one by age class (ag), 24 one by social position (sd) — and only 3 the plain national one (g). They are different measurements with different units, so get_indicator_series names the cut it returned in variant and lists the rest in variants_available, rather than presenting one as a stand-in for another. Eight of the 60 publish no series at all; that case fails with its reason instead of returning an empty result. The census is recorded and dated in tests/fixtures/obsan_variant_census.json.

Tool annotations

All tools carry MCP tool annotations so a host can reason about them without calling. Every tool is identical here — it only ever reads from the public, allow-listed data sources (BAG IDD, Obsan, Versorgungsatlas):

A host may therefore treat all calls as safe, cacheable reads. The values are declared once as READ_ONLY in server.py and applied to all 10 tools.

MCP Primitives

This server uses all three MCP primitives, each for what it is best at:

Tools (10) — live, parameterised actions that call the IDD API (above).

Resources — static, read-only reference data a host can fetch and cache, no arguments or upstream call needed:

Prompts — reusable, parameterised workflows a host can surface (e.g. as slash-commands):

Live surveillance data stays behind Tools (it is parameterised and changes weekly); fixed reference data is exposed as Resources; recommended multi-tool workflows are packaged as Prompts.

Relevance for Schools & City Administration

Schulamt / Kreisschulbehörden:

• Monitor influenza and ARI incidence in your canton
• Single measles case → alert for schools with low vaccination coverage
• Pertussis tracking → protect unvaccinated infants (siblings of school children)

Stadtverwaltung / KI-Fachgruppe:

• Public Health Reporting with structured weekly data
• Wastewater surveillance as 1-week lead indicator before clinical cases

Synergy with portfolio:

• bag-epl-mcp → "What treatments are listed?" (EPL medication database)
• bag-health-mcp → "What is currently spreading?" (surveillance data)

Datenquellen & Lizenzen / Data sources & licences

Required citation: Federal Office of Public Health FOPH — Infectious Disease Dashboard (IDD), open data via opendata.swiss. For the indicator tools, each response's provenance.source names the concrete upstream (e.g. «Sucht Schweiz — HBSC» via Obsan). Every tool response carries attribution in a provenance block (attribution + license fields) so downstream consumers can surface it automatically.
