🇨🇭 Part of the Swiss Public Data MCP Portfolio

🏛️ swiss-cultural-heritage-mcp

MCP Server for Swiss cultural heritage — SIK-ISEA artists, Nationalmuseum collections, and the Nationalbibliothek bibliography

🇩🇪 Deutsche Version

Overview

swiss-cultural-heritage-mcp provides AI-native access to Swiss cultural heritage data sources, all without authentication:

This server completes the humanistic dimension of the Swiss public data portfolio — history, literature, and art — alongside existing servers for law (fedlex-mcp), transport, statistics, and more.

The memory-institution facade (Memobase + Dodis) is exposed through three federated tools — search_heritage, get_heritage_item, list_heritage_collections — rather than one tool-family per source. Every result carries source, permalink and licence, and the licence is reported separately for metadata and for the digitised object (they diverge: metadata is open Linked Open Data, but a digitised object may be In Copyright). Only metadata and links are returned — copyright-protected full texts (e.g. Dodis transcriptions) are never reproduced.

Anchor demo query (art): "Find works by Zurich-based painters from the 19th century in the Nationalmuseum, and cross-reference with their biography in the SIK-ISEA artist database."

Anchor demo query (memory institutions): "Which sources on the development of the Zurich Volksschule in the 19th century can be found in the Swiss memory institutions?" → search_heritage(query="Volksschule Zürich", collection="all", date_from="1800", date_to="1899").

Features

• 🏛️ 11 tools, 2 resources, 2 prompts across five data sources

• 🔍 heritage_cross_search — parallel search across SIK-ISEA + SNM + NB in a single call

• 🏛️ search_heritage — federated facade over Memobase + Dodis with per-result source, permalink and split metadata/digitised-object licence

• 🌐 Bilingual output (Markdown / JSON)

• 🔓 No API key required — all data under open licenses

• ☁️ Dual transport — stdio (Claude Desktop) + Streamable HTTP (cloud)

• 📚 Prompt templates for art research and finding educational materials

Project phase: Phase 1 — read-only. Every tool is annotated readOnlyHint: true; there are no write or destructive operations. Moving to Phase 2 (write-capable) requires the prerequisites in docs/roadmap.md.

Prerequisites

• Python 3.11+

• uv (recommended) or pip

Installation

# Clone the repository
git clone https://github.com/malkreide/swiss-cultural-heritage-mcp.git
cd swiss-cultural-heritage-mcp

# Install
pip install -e .
# or with uv:
uv pip install -e .

Or with uvx (no permanent installation):

uvx swiss-cultural-heritage-mcp

Quickstart

# stdio (for Claude Desktop)
python -m swiss_cultural_heritage_mcp.server

# Streamable HTTP (port 8000)
python -m swiss_cultural_heritage_mcp.server --http --port 8000

Try it immediately in Claude Desktop:

"Who is Ferdinand Hodler?" "What coins does the Nationalmuseum have from Zurich?" "Find publications about Volksschule in the Swiss national bibliography"

Configuration

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "swiss-cultural-heritage": {
      "command": "python",
      "args": ["-m", "swiss_cultural_heritage_mcp.server"]
    }
  }
}

Or with uvx:

{
  "mcpServers": {
    "swiss-cultural-heritage": {
      "command": "uvx",
      "args": ["swiss-cultural-heritage-mcp"]
    }
  }
}

Config file locations:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Windows: %APPDATA%\Claude\claude_desktop_config.json

Cloud Deployment (SSE for browser access)

For use via claude.ai in the browser (e.g. on managed workstations without local software):

Render.com (recommended):

1. Push/fork the repository to GitHub

2. On render.com: New Web Service → connect GitHub repo

3. Select region Frankfurt (EU) — required for Swiss public-sector use under revDSG / EDÖB. See docs/data-residency.md.

4. Set start command: python -m swiss_cultural_heritage_mcp.server --http --port 8000

5. In claude.ai under Settings → MCP Servers, add: https://your-app.onrender.com/sse

💡 "stdio for the developer laptop, SSE for the browser."

For container deployments (Docker / Kubernetes / Cloud Run): the repository ships a hardened Dockerfile (non-root UID 10001). See docs/security.md for recommended SecurityContext and docs/network-egress.md for egress policy. The service runs single-instance by default; before scaling horizontally, see docs/scaling.md for the session-affinity prerequisites.

Data Source Characteristics

Architecture decision — memory-institution facade

Verified by a live probe on 2026-07-19 (methodology: mcp-data-source-probe). Four memory institutions were evaluated; only two expose a clean, no-auth, standardised interface and are connected:

Consequences: three federated tools instead of four tool-families; every result carries source + permalink + a split metadata/digitised-object licence; no copyright-protected full text is reproduced (metadata + links only); bar and landesmuseum are documented as gated via list_heritage_collections, not scraped.

Single-file server: the 11 tools live in one server.py rather than a tools/ package. At this size a single, linear module is easier to read and review than a split; if the tool count grows materially, the SIK-ISEA / SNM / NB / cross-search blocks are the natural split points.

Safety & Limits

• Read-only: All tools perform HTTP GET requests only — no data is written, modified, or deleted.

• No personal data: The APIs return institutional records (artworks, publications, artists). No personally identifiable information (PII) is processed or stored by this server.

• Rate limits: The opendata.swiss and OAI-PMH endpoints are not rate-limit-documented; use limit parameters conservatively. The server enforces a 30s timeout per request.

• Data freshness: Records reflect the upstream source at query time. No caching is performed by this server.

• Terms of service: Data is subject to the ToS of each source — SIK-ISEA, opendata.swiss, Nationalbibliothek OAI-PMH. All data is published under open licenses (CC0 / CC BY).

• No guarantees: This server is a community project, not affiliated with SIK-ISEA, SNM, or NB. Availability depends on upstream APIs.

Known Limitations

• SIK-ISEA: Artist data is updated periodically; very recent acquisitions may not yet be reflected

• Nationalmuseum: Only datasets published on opendata.swiss are accessible; not all SNM collections are available

• Nationalbibliothek: OAI-PMH harvesting is rate-limited; large result sets require pagination

• Cross-search: Response time depends on the slowest of the three sources

Testing

# Unit tests (no API key required)
PYTHONPATH=src pytest tests/ -m "not live"

# Integration tests (live API calls)
pytest tests/ -m "live"

# Lint and format, as CI runs them
ruff check src/ tests/ scripts/
ruff format --check src/ tests/ scripts/

Ruff is pinned to an exact version in pyproject.toml ([project.optional-dependencies] dev), so pip install -e ".[dev]" gives you the version CI uses and the lint gates agree with it. Installing a newer ruff on top changes the rule set and the formatter, and reports differences on code nobody touched. See CONTRIBUTING.md.

MCP Protocol Version

This server does not override the negotiation — the official mcp SDK decides, and both eras are reachable over either transport (stdio and HTTP alike). Pin the SDK, not a hand-rolled version string, to control which protocol versions are spoken. The numbers above are the pinned SDK's own registry (mcp_types.version: HANDSHAKE_PROTOCOL_VERSIONS, MODERN_PROTOCOL_VERSIONS) — read them there rather than from this table if the pin has moved.

Installation

Run via uv's uvx — no clone or manual install needed. Add to your MCP client config (mcpServers for Claude Desktop, Cursor and Windsurf; use a top-level servers key for VS Code in .vscode/mcp.json):

  "mcpServers": {
    "swiss-cultural-heritage-mcp": {
      "command": "uvx",
      "args": [
        "swiss-cultural-heritage-mcp"
      ]
    }
