Swiss Cultural Heritage MCP Server

🇨🇭 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 three major 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.

Anchor demo query: "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."

Features

• 🏛️ 8 tools, 2 resources, 2 prompts across three data sources
• 🔍 heritage_cross_search — parallel search across all three sources in a single call
• 🌐 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"

→ More use cases by audience →

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.

Single-file server: the 8 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"

---

MCP Protocol Version

The official mcp SDK negotiates the protocol version during initialize; this server does not override it. Pin the SDK (not a hand-rolled version string) to control which protocol version is spoken.
